I did this job w/o removing anything. 1/4" ratchet 10mm w/ extensions got both bolts and a ziptie around the old thermostat to pull it out. Cleaned with paper towels and used a air compressor to blow out coolant from the bolt holes. In not a small dude either and could get my arm under the intake '02 Passat w/ AWM motor.

These vids even help me on this day. My 04' Passat GL Wagon with the AWM 1.8T and 5-Speed Manual just wants to keep running. Unfortunately tho the thermostat likes to stay open so time to replace. Appreciate the walk thru. Replaced the coolant temp sensor not long ago and refreshed all the coolant in it. Figures the thermostat now wants to throw a fit. All good tho. Always ordered an extra jug of Ravenol. Live in Central Wisconsin, where it gets just as cold as Germany. Knew where the thermostat was, but it always helps to watch over another person to remind yourself of what is ahead. Thank you.

Andrii Ostapchuk No sure what you mean by "poor coolant pressure to the heater core". If it doe not overheat while driving, then it is not a thermostat issue... check your cooling fans. Check for air getting into the cooling system. The heater cores on the Passat's & A4's can get clogged, so "no heat inside the car" can be misleading some times. Check for good flow into & out of the heater core. Thanks for watching & taking the time to comment!

***** Thanx for quick reply! What I meant by "low pressure to the heater" is that I don't see coolant coming to the heater inlet (right side when facing bay). When temperature gets to 5/8 on gauge Im getting coolant goes loco from the left house from engine which I have disconnected at moment to make sure coolant coming from core outlet. Core is cleaned 100% level is good. I even bled air from secondary bleeding point and it still won't get to core. Lower rad. hoes still cold no mater what. Upper hot as hell. Any clues?

I have a 2003 1.8 passat. The return hose fore the heater broke off, lost a ton of coolant. As a temporary fixed, we got the broken plastic piece out of of the hose from the connector on the engine side, slid the hose over the remaining plastic and tightened it down, no leaks. Now the car overheats only when driving, but not at idle. I refilled the, coolant, the heater is making heat without issue. Could this be an issue of not building pressure in the system first, or maybe a stuck thermostat?
@EXOVCDS9 жыл бұрын
Make sure that coolant flows back into the reservoir when the engine is running... Rev the engine to confirm flow. A stuck thermostat will cause overheating at idle as well... you might have air trapped in the system or a loose water pump impeller... but I can't tell from here. Doesn't this Passat have a large viscous fan that runs all the time? I wouldn't worry about the a/c stuff until the overheating is solved.

Eric Henry probably not the pump then... follow the procedures that you read about. On stubborn engines I use my vacuum / filling tool. The squeezing of the hose that I usually do starts a siphon effect that works great most of the time. Pull back the hose at the heater core fitting and squeeze the upper rad hose, then, cover the small hole in the hose and release the rad hose. Oh, clamp the return hose at the reservoir shut and leave the reservoir cap off. Bleed the heater core till you get fluid out consistently.

Air pocket in the system... unless the water pump is bad. If you have heat inside then the water pump "should" still be ok. Are you only relying on the temperature needle & the overheat warning light? Do you have a scan tool so you can confirm the temperature that the ECM "sees". A bad temperature sensor can cause inaccurate needle operation. Try bleeding / filling the cooling system from more than just the coolant reservoir. Remove both heater core hoses, fill coolant into both (coolant reservoir cap off). Fill through the top radiator hose (disconnected at the radiator and lifting the hose up).

+MrDjemal10 A stuck open thermostat will cause over-cooling... but the needle should still rise a bit. The leak inside is due to the heater core being broken (removal of dash is required to fix). If the needle does not move at all, you probably have a faulty temperature sensor... the heater core could have been stressed from an overheat incident. Replace the temperature sensor / get the gauge working again and check how hot the engine is running. The core will leak with age as well, so your engine might not be overheating... but needs to be checked / solved before installing a new heater core.

My 1999 Passat 1.8t aeb 5 speed is good in summer. Stays around 190°. But now in winter here, it stays pretty cold. Usually just above the 1/4 mark. But it does have descent heat. Not amazing. But I don't ever recall thinking I'm cold. I'm trying to determine if the thermostat is stuck open? Or leaking? But the car has been this way since I purchased it so I don't know how have these cars usually run in 25°F temps. Are they supposed to heat up to 190 and hold there or close still? I am also missing my belly pan if that can be taken into consideration for added cooling. The car has a APR tune, but I do not believe that would influence it any way.

Could be a thermostat issue. Can you get the temperature / needle up to 190F by holding the rpm at 2000 for a 5min (car not moving, heater off)? If yes, after it reaches 190F, take the car for a steady cruise. Needle should stay steady at 190F, if not, then the thermostat is bypassing too much coolant. Replace the thermostat.

If you don't have heat inside the car then the water pump is bad... not circulating the coolant. I assume that you have a 1.8t engine (because you are watching this video).

If it does, then the water pump is bad. If it does not move, place the thermostat into the block, place the o-ring on the thermostat and then put the thermostat cover on top.

Make sure that all the other functions work (air flow up to windshield, down to feet, dash / face outlets etc)... if none of that works either, look for what they all have in common, power / ground supply. You might also just want to check for flow through the heater box first (disconnect the hoses when the engine is cold. Attach a garden hose to one end and check for a strong (equal to going in) flow coming out.

As mentioned in the video.... if you do not get heat inside the vehicle, then it is a good idea to check for / bleed-out air at the heater core bleed hole 16:50 With high enough rpm, the air should be pushed out of the core from coolant flow alone (that has been my experience). When replacing a heater core, I fill the core first then attach the hoses and check for air at the bleed hole. When the coolant level no longer drops in the reservoir, you can put the cap back on. The system can then build pressure, which can help push air out of the bleed hole... should any be left. Always keep an eye on the temperature gauge... if the needle goes past the middle mark (90c / 190F), something is wrong / air in the system, thermostat, water pump etc.

James McCloud Do you have heat inside the car? If you have no heat, then the water pump might be bad.

Thomas EXOVCDS mmm cold air yes, heat only sometimes when the temperature outside its hot, but before the coolant was gone the car was working fine,no overheat none of that problem.but now i have that problem

James McCloud Did you lose coolant because it overheated or did you lose coolant and then it overheated? If the engine has an air pocket, that can cause the engine to overheat. Try bleeding the cooling system at various locations... to remove as much air as possible.

I’m havin over heating issue took thermostat out and it was stuck closed but when it over heated I had heat then when it heated up it went to cool like the air did so what could that be heater core or what ?
@EXOVCDS4 жыл бұрын
If it's a 1.8T passat... it could be that the water pump impeller is loose (causing no circulation of coolant through the heater core). The stuck thermostat (if it was stuck closed) could have stressed the water pump, causing the plastic impeller to come loose. You can check the water pump impeller by removing the thermostat cover and reaching into the block to try and turn / spin the water pump impeller. If the impeller spins, then the water pump is bad. The other possibility for no heat inside the car, is air in the system. If you did not bleed all the air out (after having removed the thermostat) try running the engine at 3000 rpm for 5 minutes. The higher rpm can help push air out of the engine & heater core, back into the coolant reservoir. Obviously keep an eye on the temperature gauge when you do this... needle should not move past the middle towards 3/4. If it does, something is wrong. Shut the engine off and allow to cool down.

How do I bleed out an air pocket
@EXOVCDS10 жыл бұрын
Dance Unlimited Make sure that the small return hose (that is attached to the reservoir) is free to flow fluid / not plugged (disconnect it and blow into it to check). Fill as much fluid as the reservoir will take. Squeeze the upper & lower radiator hoses to get the fluid sloshing which "should" cause the fluid level to drop. In some cases, you need to either remove a coolant temperature sensor from the system, so that air can get out. You can also remove a coolant hose (just remove it a little bit from the fitting that it attaches to) so that air can get out. Did you work on the system or are you having overheating issues all of a sudden?
