Coolant System Service Nissan 350Z & Infiniti G35 (Replacing Thermostat and Hoses) | AnthonyJ350

Make sure the Engine is COLD! We service the cooling system in the Nissan 350Z. We wanted to upgrade the cooling lines, while doing that we might as well change out the the thermostat so we don't have to think about it for a while.
You will have to bleed your cooling several times on a VQ motor in order to get all the air out. *Do not drive the vehicle if it is overheating*.
Always consult your service manual before working on the vehicle.

I bought the OEM thermostat for my 10 G37 Coupe w/74,000k last week at Nissan dealer for $26. Same part # as Infiniti. Make sure you get the OEM gasket as it doesn’t come with thermostat. I paid $6.50 for that. Definitely remove parts he recommends This job is EASIER than replacing the cheap plastic heater hose connector which blew as a result of the bad thermostat.

[@AnthonyJ350]

Thanks for sharing your experience! Hope the car is running well.

[@supras7]

Haha i was about to do my coolant flush this week , thanks for the vid! Hopefully HR is the same

[@AnthonyJ350]

You'll have to add a step and run clean water or distilled water through the system before you refill

[@stealthg35infiniti94]

What I have done in the past, I did the bleeder valve to fill as shown with the heater on maximum... Then fill the over flow tank to the top of the cap...The system will burp through the radiator cap then suck coolant into the radiator once the engine cools down...After 5 heat cycles ,the coolant level will be exactly on the FULL mark....It almost appears as if the overflow tank was designed exactly for burping after coolant change.

[@AnthonyJ350]

Thanks for sharing!

[@jrock9687]

Exactly! Can't be done in one shot. Took me three heating/cooling cycles to get the system fully bled. With that Lisle funnel the level will keep going down every heat cycle. Just keep topping it off an the system will eventually burp itself w/out having to even touch the bleeder screw.

[@BoOmBaMan]

Sweet vid AJ. Mishimoto thermostats have a higher temp threshold versus OEM. Aisin are good too. Some VQ owners I seen don't use factory coolant and they wonder why the engine blows up along with not topping off the oil.

[@AnthonyJ350]

You mean the Mishimoto opens earlier right? I like the Aisin one cause it was made in Japan and my Dad's work sold a lot of that brand with little issue. Trying to keep within factory parameters.

[@AnthonyJ350]

Ya you can't go wrong with factory coolant. I think it's typically the best, especially because it's formulated for how they design the system.

[@BoOmBaMan]

@@AnthonyJ350 correct. Opens early and can withstand 10-12degrees hotter than OEM

[@BoOmBaMan]

@@AnthonyJ350 by design of other aftermarket thermosats that says oem spec are red flags. Spring tensioners are not the same as the ones made in Japan

[@AnthonyJ350]

Do you run Mishimoto right now? I'm unfamiliar how the VQ likes that thermostat setting.

[@billnumby1080]

Well done, AJ have you had any issues with the Aisin thermo? It looks identical to the Mahle(made in Japan down to the green tag) I'm fixin to put in. I have only seen one other, silverstone 2006.5 with lower miles than yours, mine with 40k.

[@AnthonyJ350]

Cooling system has been great since we made the video. I've also been driving the car more in the colder weather this month since my truck is in the shop getting the top end redone.

[@weedislegal4me2]

I drill 8 tiny holes in the outer ring of the thermostat ( steam holes ) It greatly reduces the bleed time, and those steam holes prevent air being trapped, and possibly burning a hole in the intake manifold from hot spots. I recommend doing that to all thermostats. One less possible fatal motor mistake.

[@AnthonyJ350]

Thanks for sharing!

[@OldSchoolNoe]

Ah there you go I commented on the "coolant bleeder replacement" video not knowing you already had a video showing the complete burping process. I still figure that you don't even have to open the bleeder, funnel takes care of everything. At least that's how it is with my Ford.

[@AnthonyJ350]

You'll want to crack it open when you refill it. These cars have a hard time bleeding.

[@arloc74]

I have an HR and want to do my thermostat as well, but my question is what made you go with an after market brand but same specs, wouldn't it be better just to get the oem from Nissan?? Awesome video man

[@AnthonyJ350]

Are you referring to the thermostat? I picked one that was made in Japan because I knew it would be good quality.

[@JAKWEES]

Hey Anthony, my Z has 85,000km should I replace my thermostat as a preventive measure? Or do you think it’s fine for the time being unless it gives me an issue

[@AnthonyJ350]

I would change it the next time your change the coolant. A thermostat can either fail open or closed. You don't want it to fail closed in the summer.

[@austinbradley3411]

Hey so I'm just confused on the steps you took. So you filler her up went and held at 2500 rpms for 10 secs. Then went screwed off the pressure valve in the back them tightened it. The. Burped the upper hose. Filled with more coolant in the funnel. And repeated a bunch of times. Correct?

[@AnthonyJ350]

Correct, don't be surpised if this takes at least 45 mins to perform.

I'm curious on whether I can replace it without having to remove the alternator . I see where it connects on bottom but not on top . Any advice on what i should do is welcome

[@AnthonyJ350]

Not sure honestly. I plan to put a silicon one in from Z1 possibly this year and you can watch the video. If things are in the way, I would remove the alternator so you can access it better. You might also want to pick up a service manual and study it to give you a plan of attack to take on the task.

[@rafagas5150]

What if when after letting it cool down and you try opening the cap but the antifreeze Wants to come back out?does that mean there’s a lot of air that want to come back out?heater on gets hot when I’m revving it once I let go it stays warm.any help or suggestions would be greatly appreciated

[@Bonny_Kratos]

Hi, I have problem with my car. I was chnaging knock sensor harness, and i was dissconecting throttle body heating and some coolant spil out. After i changed the harness I assembly it again. Hit the road and after 5-10km (3-6mls) car started overheating and reservoir was overfilled. I heard something about that this engine is really hard to bleed. I tried it like 10 times and every time it overheated again. After air bubbles stops comming from the radiator what should i do? Let the car completly cool? for how long? after that top the radioator and close it? A really dont know what to do, every garage is telling me that it is blown headgasket but it is bullsh*t. The car runs fine before I disconected the hoses.... Thanks

[@AnthonyJ350]

Did you let the car warm up with the bleeder screw out near the firewall?

[@walkins1992]

Can someone tell me what specifically the long hose is called on Z1 for the DE. Mine is busted and just looking to replace that hose or should I just replace all of them and not just the one ?

[@AnthonyJ350]

I would replace all if you can as preventative maintenance.

[@DarkVividdream]

Question so I am new to doing the bleeding when doing the bleeding you hold the gas at 2500 rpms for 10 seconds and turn the ignition off or leave it on idle ? And how long do you wait until you step on the gas again and will the funnel automatically stop when the radiator fluid is filled to the top ?

[@AnthonyJ350]

I would do 2500 RPM off and on until the cooling fan turn on. Then I let it idle for like 20 seconds then shut it off. I then repeat the process till the bubbles stop.

[@DarkVividdream]

AnthonyJ350 awesome thank you so much !!

[@loslakers530]

Hey bro so the at the end the radiator is supposed to suck all of the coolant fluid back into the radiator as shown in the video?

Damn! I didnt know you had swapped out your oil pan! looks clean

[@AnthonyJ350]

Ya wanted the extra capacity cause of the oil burning thing. I'm going to add the Mishimoto oil cooler next. Saw your radiator video looks good. Do you think the thin fan setup from Mishimoto will solve the tight clearance with the AC compressor?

[@Z33Garage]

[@stopher1971]

I have a question I just noticed that when I first start my car cold, it builds up pressure, but not enough to push coolant into the reservoir, and when it reaches operating temperature, the pressure is normal coolant and the reservoir never gets above max and then settles to minimum when it’s cooled now with the radiator cap off and a spill free funnel. I start the car up and it pushes coolant out into the funnel, maybe about 6 ounces or 8 ounces and then stops and stays there cold and at operating temperature, does not overheat, cruising its at 178° to 183° and fluctuates in traffic as normal no air bubbles in the reservoir or the spill free funnel cold or operating temperature, everything is operating completely completely normal. I know this is a symptom of a leaking head gasket, but everything is operating perfectly as it should. Is there something else that causes pressure when it’s cold?….. it’s been doing this for nine months with no issues and I’m not losing coolant either and the heater works great.

[@AnthonyJ350]

The plastic overflow tank or the radiator itself?

[@stopher1971]

@@AnthonyJ350 if you’re asking me which one is building pressure. Its the radiator because the overflow tank is vented.

[@Mindset4Excellence]

This is great! I'm planning to swap upper and lower radiator hoses this weekend and find this video to be one of the most helpful. From what I understand, my 2008 G35 with 3.5 L VQ35HR engine (vs VQ35"DE") doesn't have a bleeder screw, however, there's an Air Relief Plug "on radiator" (driver side) that should be opened on refilling and closed when coolant begins to flow out. I'm hoping using this procedure (w/ spill-free funnel) in combination of Air relief plug on radiator will work the same! At the very least I can follow the exact steps in service manual which doesn't involve using spill-free funnel, which means you must close radiator cap, and wait for car to cool each time. For anyone wondering, I got the manual from here: cardiagn.com/2008-infiniti-g35-engine-cooling-system/ P.S. The service manual does make mention of an Air Relief Plug on "heater hose" (i.e. bleeder); however, I've read differing comments of some saying it's there and it's not. Apparently, Infiniti started to phase them out post 2007 model. In fact, if you check the following link and select 2008 Infiniti, the OEM Coolant Bleeder Relief Valve shows as Not Compatible. conceptzperformance.com/nissan-infiniti-nissan-oem-coolant-bleeder-relief-valve-nissan-350z-infiniti-g35-92500-ar000_p_15693.php

[@Mindset4Excellence]

@@AnthonyJ350 I’m totally fine with time even if it takes 2hours. My main goal is to ensure it’s done right 🙂! Only question I have...as you were going through the cycle of topping off coolant and rev’ing engine and holding at 2500/3000 rpm...how long did you wait “in-between”those events? Meaning, you started by filling coolant, open bleeder until fluid comes out then close, start car and turn on heat, rev engine, as fluid decreased in funnel you topped off (and I’m assuming you slightly opened bleeder to bleed air then closed), then went back to rev engine... how long did you wait after topping off before you went back to rev engine, or how do you know when to? Is it when coolant stops moving(increase/decrease) and/or when you no longer see bubbles? Is that the point when you know to rev engine again?

What if you do this and then after you move it outside and when you rev you can hear the coolant sloshing around? More air in the system and need to do again?

[@nighthawk0077]

You want to use soft water instead of distilled. Distilled water is chemically unbalanced and will attracts electrons from metals.

[@AnthonyJ350]

Thanks for sharing!

[@skrtskrt3429]

That’s deionized water. Distilled is perfectly fine.

I did this as well as changed the coolant sensor and replaced the radiator cap for a new one rated 88kpa which is what the OEM said on the top. My car is overheating with ac on :/.

I would really avoid reusing factory clamps. Clamps are cheap peace of mind.

[@AnthonyJ350]

What's wrong with the tension clamps? They can't ever back off. But they are difficult to use some times.

[@Wrought_Iron_Wolf]

My factory tension clamps didn't fit onto the mishimoto front bypass hose. Had to get new clamps for this part unfortunately, but otherwise the hoses are great!

[@ahumm8280]

I have to disagree about those new hoses sweating. I have been dealing with silicon hoses for years working on cars and trucks and they do not sweat. If so, they are on the verge of leaking! Also I have the master set from Z1 for my G and while we're in the dead of summer I have yet to encounter or ever heard of coolant hoses sweating!

I hope so cause that would make my life easier.

Distilled water is better than any coolant

[@AnthonyJ350]

You still need coolant for anti-corrosion inhibitors, lubricant and it raises the boiling point. Also need it for colder climates.

[@AnthonyJ350]

But yes distilled water is better as a heat exchanger. If you put an oil cooler on even better.

@@barryhall7 Yes but they don't degrade like rubber hoses do either. In theory they last as long as the vehicle. So they're not worse, they have different properties so different issues. As a vacuum line they're perfect. I think you're assuming too much here without enough context.
