2004 Volkswagen Jetta car overheating

This is a 2004 Volkswagen Jetta overheating. The car was not really overheating but I did not figure that out until later on after I finally got home of thinking that the car was overheating. I left the car in the driveway and it is freezing out. When I got back home that night at 12 o'clock midnight I started the car the engine was frozen cold. In a matter of a minute it went straight up to normal 190°F which is normal temperature when the engine warms up. So I knew that was impossible that it got that that hot it never does that. Then in the last part of the video the This is a 2004 Volkswagen Jetta overheating.

Then in the last part of the video the coolant temp sensor was telling me that I was overheating in a matter of three or four minutes of running on a frozen engine and that was not even possible. From that I knew it was that coolant temp sensor that was sitting in the anti-freeze the electronic one was broken. I replaced it today and I took a drive on the highway and never overheated again and was at 190° the whole entire time I was driving. Problem fixed for $30 and about 10 minutes the sensor was telling me that I was overheating in a matter of three or four minutes of running on a frozen engine and that was not even possible.

Removing the coolant cap was a great tip. Saved me from coolant to the face.

[@andrewnewman8844]

thanks i fixed my audi 2.7tt wagon your a life saver

[@elcubanito954]

That part is called the coolant temp sensor, not the thermostat as it says in your description, just so people don't get confused. Otherwise, nice information :)

[@marcibm1]

thanks I must've missed worded it. Fix now thank you

[@victoralcantara9255]

Thanks you help me a lot man

[@snachez]

Thank you. Some other video was saying to drain the fluid and do all kinds of other stuff. But that didn't sound right to me.

[@marcibm1]

no problem glad i can help

[@JohnSmith-xd7zd]

I have a 2005 1.8T Jetta and the temp gauge is stuck on the gauge cluster? Any suggestions?

[@ironbloodedmyth1204]

Could a bad sensor cause a misfire and dead battery? Because I already changed all my plugs and coils on my VR6 and I still get a code for Cylinder 2 and P0118 for Coolant Temp Sensor

[@tcreech592]

that is not an electric thermostat. that is the temperature sending unit. its like 7.50 at a parts store. it takes temp of coolant and sends it to gauge on instrument cluster. then when it shorts out it gives false reading.

[@marcibm1]

Do not buy from a parts store. I did that and a week later was having the same problems. Went to Volkswagen and got OEM part and never have that problem again i have 75,000 miles now and did not have that problem again. Instead of paying $7.50 by OEM part $8.55 for a better part and that will last loonger and save you from doing the same job over.

[@eddiesan915]

Great video. I have a question does the clip that holds the temperature sensor goes all the way in? Or does it stay as it was shown on the video? Thanks for everything and God bless you.

[@eddiegarza6914]

there is a gap in the clip

[@marcibm1]

Okay then it is the water pump it's not pumping

[@marcibm1]

Vw Jetta have a plastic water pump. If it's still overheating then it is the water pump. Not the relay of the fans that would be the last thing I would check

[@marcibm1]

Yes the clip pushes in but not all the way it sticks out a little bit

[@karlos6628]

+marcibm1 - so your fan was not working ?

[@zzzysr]

2001 Audi TT 1.8t AWP. I recently changed my coolant temp sensor with a aftermarket BWD and now my fans don't work unless I turn the AC on. Note I got some coolant on the fan connector. Do you think the fans may not be turning on because I didn't buy OEM or because there is an interference with the connectors?

[@marcibm1]

The first one that I got was an aftermarket is failed after a week. I never get parts that are aftermarket I always have problems I always get OEM parts

[@wellheeled88]

There are aftermarket water pumps with a metal impeller. They cost about three bucks more IIRC. My take on the plastic impeller is that it sells alot of new cars. A new pump installed at the dealer is about $1700 and they normally fail around 100,000 miles. How many people trade the car rather than paying the huge repair?

[@snoopy5736]

They sure are a pain to replace the water pump. I replaced it in my 04 v6 2.8 passat, had to remove the timing belt

[@mikebeezyify]

i had a broken y flange that comes out of my reservoir for the coolant and i replaced it and now the car still overheats. but there is no leaks anymore and the fans kick on and everything but still overheats, any ideas? thanks

[@marcibm1]

No problem

[@onefunnyfatguy]

When you had this problem did your fans come on or no and did you have any heat cuz mine is doing the exact same thing I can't even drive more than 4 miles without it jumping all the way up into the red but when I try to turn the heat on the cool it down there was no heat it just blows cold air but there's no leaks on the heater core cuz I checked the floorboard and on the inside and outside

[@robertwhite9426]

I'm having the exact same problem, besides the cold air/heat part. Any luck getting it fixed? I'm stumped on what to do. I replaced my thermostat, water pump, thermoswitch, cooling fan control module. Still no luck.

[@onefunnyfatguy]

Its the water pump

[@bornintherain]

+kevin lakey my Jetta was overheating.had the water pump replaced. Cheap plastic fins on the pump. Cost me $320.00 to replace. Never will I buy a vw again.

[@marcibm1]

Yeah the only other reasons why that would happen is water pump or the thermostat is stuck close that sits in your coolant and opens up when the car gets to operating temperature maybe be stock closed and causing the car to overheat.

[@marcibm1]

The reason why they make plastic water pump is so when it breaks it doesn't cause internal damage to the Engine. I've never heard of a metal one breaking. But if a metal one break you can just imagine where all those pieces of metal will go into your engine and clause problems.

[@sarawutkositworawut7085]

hi I have the similar problem with you but I check on my sensor by using clamp meter its working. could it be anything eles the broken? thanks

[@marcibm1]

If the water pump is not circulating that could be a problem. Or the thermostat that sits in your coolant and opens up when the car gets to operating temperature maybe be close and causing the car to overheat.

[@4darin5]

Part number?

[@Taylordmakeup]

I’ve got a 2003 automatic jetta and I haven’t driven daily yet mostly bc i don’t have my license yet, but it has 82000 miles. could you let me know how i keep up with the maintenance ? because ik these cars have engine problems and i don’t really know what to do to keep it from having big problems. thank you

[@marcibm1]

I put synthetic oil in my car makes a big difference. Flush radiator fluid and replace. I had my timing belt done because it was dry rotted and the water pump. Water pump in these cars are made of plastic and they break from being in hot water all the time. When the guy took my apart he said not all of the fan blades were there. After I did that car ran smoother like when I got a new. Also had the transmission fluid drained and filter replace. Other than that I also had to replace the fuel pump because it went bad. Spark plugs more replaced as well as coiled because the Coil box was cracked. And if it cracks enough water can get inside when it rains or moisture and it will stop the car from starting. But otherwise the car is running great Drive like it's new now

[@Taylordmakeup]

marcibm1 thank you so much. my dad works on cars so i’ll definitely have him help me. i appreciate it man. do you go to a local shop or do you do the stuff yourself? if you do both which do you do on your own and which do you get done by a professional ?

[@austinhillegass1763]

my mk4 gti,makes this bucking thing when cold

[@eddiegarza6914]

did that cause your radiator fans not to come on as well?

[@marcibm1]

I did not hear them it was really cold and snow on the ground so it wasn't like I had my windows open to hear the fans going on. When I pulled over they we're off.

[@kwlm29]

electronic thermostat?

[@marc2116]

coolant temp sensor not thermostat

[@bemochop4356]

My dog 👍

[@diego6697]

sounds like Link is low on health

[@EvilSl0th]

my o2 jetta just started throwing the etc code. going to replace it. canadian tire charged me 67$ to scan the engine... then said it would be about 200$ to replace a sensor... plus tax. so we are looking about $300 total. i had them clear the code in case it was just random. came back on my trip home. plugged my own obd2 scanner in and connected my cell phone to check the code. same one. so ultimately, this should cost me just 30ish bucks to fix. from now on, i scan my own damn car!!!

[@snoopy5736]

Was the bad sensor giving you the epc light?

[@AGuysGarage]

looks like a coolant temp sensor.

[@marcibm1]

Rhage73 yes it is the coolant temp sensor

[@michoacan91davi]

we're you getting code p2181

[@marcibm1]

Using the scan tool that's where the code came up on

[@jeffhector1569]

Hi does your car overheat and high pressure with this issues pleasw

[@marc2116]

Never overheating never had high pressure. Had the what are pump replaced because it's made out of plastic, many years after when I had the time belt done.

[@marcibm1]

it will overheat if your water pump dos not have all its fins on it. when i had my water pump replaced there where only 4 fins left on it. my car wasn't over heating it was just the sensor that went bad. but if i did not get the water pump replaced about 10,000 miles after that I would have a problem later on with it actually overheating.

[@bmw-e30]

The sensor does not cause the problem---it reports that there is a problem in the system!

[@tengzturiagaiii3185]

My 1.8 t over heated you think that's the same problem? What about the thermostat,should i replace that too?

[@marcibm1]

What made me no it was the sensor was the way the fluctuation in temperature from normal to high and it would bounce back-and-forth sometimes very weird and I knew is that.

[@marcibm1]

Vw Jetta have a plastic water pump they fail close to 100,000 miles or before. If you are still getting your engine overheated more than likely the pump is not pumping.

[@tengzturiagaiii3185]

Mine failed at 63thau.

[@marcvonsalzen4239]

val turiaga not bad for a plastic water pump so dum that they do that

[@tengzturiagaiii3185]

Yeah and for a turbo too. Hehehe. Yeah i got my.1.8 fix. She's back on the streets. Worked on it myself.

[@YouraN1993R]

$30? That part costs $9 at orileys

[@mrfourtysevenman]

I've had one of these turds. EVERYTHINGS FUKKEN PLASTIC! fuel rail? plastic coolant lines? plastic hose fittings? plastic water pump? why the fuck is that plastic? WHY is it on the timing belt??

[@adrianbrown8555]

The thermosat or the housing is broken comon faults on all vw or audi come accross this nightmare four weeks later was back again faulty thermosat housing broken

[@integridad7]

Say Something!!!!!!!

[@joevillanueva6598]

That's not a thermostat bro

[@eddiegarza6914]

well i tried that and it didnt work next step is replace the fan relay undernieth the battery..

[@benjaminbutler2388]

Dude what's your fetish with this clip?
