Hard Start, Overheat -Part 1 (Nissan Pathfinder)

[@annamariequigley6594]

Come on guys. Tell you're friends about Ivan's channel. He deserves way more subscribers than he has.

[@jeeprose4712]

I have been watching Eric O for a long time and knew about you, however I just started watching and I really enjoy your videos they are fantastic. I enjoy the way you are able to explain everything so logically and effectively. You keep the process going and don't get bogged down trying to over explain. I don't have a scan tool, however if I don't need to understand every detail as long as I understand where and why your getting there.

[@mikechiodetti6737]

2006 Pathfinder. I have a 2006 Frontier V6, 6 Speed Manual 4WD. HMMMM. Now you've got my attention. I replaced the coolant sensor AND ALL the coolant hoses last July when I replaced the timing chains, tensioners, guides, water pump and thermostat. Lota parts, lota work. Done with the tensioner problem. The hoses and sensors (oh ya, the two cam sensors also) are peace of mind! I wanna see part 2!

[@wyattoneable]

Wow, that hose was minutes from busting. Good thing you found it in the driveway. Good for us because it was a surprise and good for the owner so he didn't have it happen while on the road.

[@dm9030]

ivan, all your customers must admire the fact, that you're working so late, out in the snow. Seems you're a dedicated techician, who sees his job also as a hobby. PS. ignore all the haters, they're just jealus of what you're doing.

[@jomangeee]

Ivan you are a trooper! Love these videos with a cliffhanger, how about you give us options at the end of such videos to make it interactive for example: 1-ECT code will disappear and RPM normalize when coolant sensor is replaced 2-Throttle body will require cleaning 3-PCM failure 4-Throttle control motor replacement 5-throttle position sensor replacement 6-crusty wires 7-non of the above

[@PineHollowAutoDiagnostics]

That would be fun!

[@robertevans6481]

I know that I was not the only one that ducked when that hose popped...and smell coolant as well. They are in good hands..

[@2secondslater]

Glad you didn't get burnt, Ivan! Nissan Pathfinder and Navara heater hoses and pipes are so common for blowing or breaking. Great diag on the sensor.

[@davidraezer5937]

Good job Ivan! You inadvertently prevented severe engine damage for the customer. They would have had the hose fail and with a coolant gauge issue they would have kept driving it. Gotta love the hot coolant bath the the taste of glycol in the evening 😀

[@PineHollowAutoDiagnostics]

haha yeah it was sticky lol

[@petemedina8446]

That was very interesting I'll have to remember this if I run across this problem or know someone who this type of vehicle. Look forward to part 2

[@billneu9520]

As friends fixing our cars in the 60s, we would say every came out copasetic meaning perfect with no problems. After you diagnose the problem and repair.its copasetic thanks for your videos and time Bill N LINY

[@iduimovic]

Those Pathfinders from 2006-2011 are a beast off road 7 seat SUV. They are bullet proof and the 4WD system works awesome. I have one and take it to everywhere and it can take a beat. The only stuff that any Nissan owner with the VQ40 engine (V6 4.0L) automatic is to bypass the transmission coolant system. Removed the hoses from the OEM radiator and add an external transmission oil cooler and that's it. You will save your transmission from any catastrophic failure. The OEM radiators on those vehicles are well known of internal failure that it mixes the coolant with the transmission oil and push that coolant to the inside of the transmission and it destroy all the clutches, rubber seal and solenoids. And there is no way to know that happened until your transmission quit. Beside that easy and cheap fix if you do it before it happens you have a real reliable SUV that will last very long time with out any issues. Just like any other vehicle just make sure you do the proper preventive maintenance and keep the regular service done on time. Looking fwd to see the fix.

[@weldingjunkie]

I D I’ve never heard of this before is it prone to the 4.0? I’ve worked on many 100’s of VQ35 and 2.4 and never seen any issues with the coolant hoses it’s self. The 3.5 has an external filter.

[@iduimovic]

@@weldingjunkie it is specifically on the 4.0 vq40 engine. The problem it is inside the radiator not outside so you wo t see the issue until it is to late.

[@weldingjunkie]

I D thanks for the heads up I’ve not seem too many VQ40 they have less problems than the sedan motors and tranny the RE0F09A tranny are pos.

[@djentyman4002]

Said no one ever haha Nissans are absolute junk and have been for 15 years. Even worse now.

[@midnitemonty]

I have a 2007 pathfinder with 200k an I did the radiator replacement b4 it detonated my tranny..its never left us stranded, but has shit quality. The engine whines just like this one in video due to crappy plastic timing chain guides for well over 70k miles.. not replacing those..

[@AP9311]

I swear I had that exact same thing to me couple months back. I parked my blazer to gas station, came back with crank, no start condition. Kept on cranking until it started, but my idle was all messed up and driving was all weird! But I did notice my temp gage was not working. I did the wiggle test, everything was back to normal. A week later. It did the same thing. I checked the sensor, good ohms, etc, but the plug was messed up, like pried up etc. I got a another pigtail from junk yard, cut the old one of and splice into it. Problem went away, never came back ever. Hahaha!! No parts cannon required, except for the pigtail which cost me nothing lol

[@focus82grothm]

Wow glad you're okay. I believe you know it, but i remember my old 02 Ford focus cuts out fuel to couple of sylinders when it's overheats. It's a safety thing. I experienced that when i changed the coolant and i had trouble to bleed the system. The air got trapped and i had trouble to get it out, was forced to take a drive with it to try to free up the air bubble and then it got to hot. In the end i got the air out of the coolant system and no damage was done fortunately. Ironically it was the overheating that got the air out. Wish you good hunting.

[@Strikedown2k]

Ya know, my brother hates that I wiggle everything when I am fixing something unrelated to what I'm wiggling. This hose blowing is exactly why I do it. Best to find it when you aren't on the road.

[@ninjatechauto655]

Might want to recommend timing chain and guides. The whining is a sure giveaway they are worn causing the whine. But awesome job. Can't wait till part 2.

[@kellyrjohnson7693]

Awesome, another PHAD vid! Just finished watching the last one!

[@joe2mercs]

It would be interesting to monitor your engine cycle to see if jumps between ‘open’ and ‘closed’ when the coolant sensor drops on and out.

[@somerandomguy3868]

Prognosis is good, perhaps some fluid film after a couple of salvos from the parts cannon

[@2aminitials]

After watching video guessing dirty throttle body / needs closed position reset. Also needs new coolant hoses everywhere. Was the coolant green that blew out of the hose? My 2012 takes blue coolant, at least the OEM coolant is blue anyways. Maybe it's different for that model year.

[@PineHollowAutoDiagnostics]

I didn't get a chance to see the color of the coolant before it sprayed my face haha

[@tremblingone4269]

Pine Hollow Auto Diagnostics , Which highest output does your model have?

[@leebarnes655]

F150 had an odd overheat code stored in it and it wasn't in my $7 scanner booklet either. so I had to write it down, come home and look it up. Their strategy was to shift it into a 4 cylinder by inhibiting the injection of fuel every other round and alternate the dead set of cylinders. Well nobody complained of this so I assumed it was just a case of grounding of the temperature sender. Never came back either. But I would have never guessed that it would do such a thing in the first place.

[@willefixit]

touched it and it broke. hate when that happens.did it ever really overe heat ??to fry sensor?

[@danrascal4045]

Could it be the sensor cable? Bad cables malfunction in cold temperatures.

[@tomvleeuwen]

It doesn't matter if it is your fault that the coolant hose broke, or even if you could do anything about it. What matters is are you able to explain it to the customer, or is it easier to hide the price in the labor, since you were very quick with the diagnosis?

[@Pr0ph3cy-k5z]

If I was the customer, I'd want to see the video first. After watching the video, I'd be willing to pay for the part/labor. If I had to rely just on what the mechanic told me, I'd probably refuse to pay as well as leave a bad review. If I knew the mechanic real well, I'd take his word for it. After following Ivan long enough, I'd take his word for it.

[@publicmail2]

Sometimes we get so excited finding the problem we are not in a rush to fix it.

[@BigDog50001]

Well that’s one way to find a coolant leak.... ;)

[@arthurfricchione8119]

Ivan glad you didn't get burned or damage your scanner. Know you said your going to change the ECT but at the end of the video were you talking about P2119 ETC Actuator. Is that the Electronic throttle control. in the video, it sounded like you said ECT again. Anyway, good video and looking for the conclusion ❤️️Looks like 104 degrees is failsafe mode and looks like the throttle gets its opening signal from the ECT sensor. Anyway just looking at the wiring schematic to try and figure it out on my own. Am I close?

[@deyvidcardoso3318]

VERY GOOD MY FRIEND, I LIKE YOUR VIDEOS. GOIANIA BRAZIL

[@sinegra30]

11 Nissan Dealer technicians disliking this video so far... Thank you for this video, for some reason I also broke one of those Hoses by just slightly touch it, if I am not wrong that is a hose for the HVAC heating in the cabin, mine was on a Nissan Frontier truck with pretty much the same engine and HVAC System, looks like those type of hoses get all toasted with time and engine heat, is good you had it in tape for the customer in my case I had to argue a lot and lose a customer...

[@georgebonney90]

Do u think air in the cooling system could be causing the idle surging?

not in this case.

At the intro, when you paused after the welcome, I thought you were going to say 'can you dig it?' and start laughing. LOL

[@arsinoeivlostprincess4228]

I guess it goes into "limp in" with reduced power and odd running. I've seen the temp gauge go up and down quickly only once on an old Escort. It was 0 degrees F out and the stat would let some water through quickly hit by very cold air hitting the rad. . The stat would snap shut and repeat with gyrations in the analog temp gauge. Old stat I guess. Stats used to be a "rubber" seal containing an expanding wax material. 170k is a long time. May be a contributor. Even with the wiggle test.

[@Google_Is_Evil]

I wouldn't start firing my parts cannon before I have visually verified that the short doesn't occur because of a frayed wire hitting the chassis when you wiggle. The sensor low and high errors together can not yet be explained nor were both recreated, unless you assume (dangerous) that they were set by a mechanic unplugging the sensor and then not resetting the codes after.

[@amadafaka]

05 Xterra plastic at the heater core are prone to failure just like all BMW plastic coolant parts.

[@VoltageDropDiagnostics]

Man, that hose blowing in your face could have turned out a lot worse. Glad it happened before it was at operating temperature, and glad you didn't get hurt.

[@johnaclark1]

Not too long ago I was simply changing the oil on a 2006 Mercedes CLS55 AMG. The filter cartridge is on top near a very small coolant line from the upper radiator hose to the overflow bottle. I just bumped it with my filter wrench and the tiny plastic fitting snapped off and shot hot coolant everywhere. Crap! I went to remove the tiny hose from the overflow bottle so I could replace it and the overflow bottle fitting area started to crumble and disintegrate while just pulling up the metal clip. Needless to say I was pretty frustrated having taken a car that was just in for an oil change to broken down until the next day when I could get parts from Mercedes. I did not eat that. Wasn't my fault. Stuff happens.

[@keithy4129]

If I brought my car in for an oil change and the tech busted a hose, I’m sorry but they are paying for the hose, not me. Not the customers fault you hit it with the wrench.

[@johnaclark1]

@@keithy4129 Didn't "hit" the hose. Just touched it with the filter wrench and it virtually fell right off. I feel the same as you but when the coolant bottle itself started to disintegrate it was obvious it wasn't my fault. Customer was just happy it happened here and not driving down the freeway. With 12 year old plastic, especially on Euro trash, anything can happen.

[@PineHollowAutoDiagnostics]

Actually customer should pay the mechanic EXTRA for breaking that crappy fitting, since that is saving them from being stranded down the road ;)

What can people do if they can't even rely on their dealer to know how to repair a vehicle? Something is wrong with the vehicle design and manufacturing process if it takes a rocket scientist to diagnose the problem!

[@Sagittarius-88]

There's a multitude of issues with the repair industry these days. The largest issue is it just isn't worth the time and effort to become an auto mechanic these days. I spent 25 years in the private repair sector before I finally got out of that side of the industry. Now, I work for a major auto auction company, on the wholesale side of things. I work less hours, have better health benefits, and make more money than I would in the private sector. Best part of all, the vehicles we work on get sold at the auction and go away forever, regardless of what kind of issues they have. I wouldn't recommend becoming an auto mechanic to anyone these days. No way in hell I'd ever return to the private repair sector. It simply isn't worth it. To be fair, there's nothing wrong with a little do it yourself know how, but the simple truth is, the automotive repair industry simply doesn't pay anywhere close to what it should. As far as dealerships, they'll pretty much hire any warm body that comes through the door, throw some training at them, and hope things work out. That's pretty much your state of affairs with the automotive repair industry these days. In a nutshell, it sucks. But hey, if your local grease monkey is ASE certified, he's got qualifications, right? Lmao..

[@BigMac2222]

I've worked at a dealership and they don't do anything special there. They're only as good as their brightest tech, which will never be anyone other than the ones that happen to apply for the job.

[@RicardoPCGamer]

My stepdad has a Frontier, the engine will be revved up for a couple minutes, before it goes down to idle. It idles high a lot longer when it is cold.

[@CPUTests]

When you touch the ECT and the FANs starts to work the PCM knows the engine is already at temperature and the RPM should be less than 1000 and this is not happening in this car so there is a problem. Every car IDLEs high when cold. That is obvious but not when it is hot. In fact after you start the engine after 5 to 7 minutes the RPM should be close to 850 RPM (depends on the engine) but never at 1000 RPM.
