  3. 2.8L V6 Block Drain Plugged - Question About Possible Solution

    Volkswagen Passat B5 Discussion
    Bought a used 2005 Passat V6 with 78k miles on it. Very very poorly maintained and needs a paint job but I think it has a lot of life left in it. Really bad mechanics have been at this car based on the number of missing and broken screws just getting it into radiator service position. Anyway, I...
  4. Car not staying at temp, bad thermostat??

    B5 Garage
    My new to me B5 Passat 1.8t is having some issues. The first drive of the morning the car takes FOREVER to reach the 190° mark on the coolant temp gauge. After it reaches that point it’ll stay there for a few minutes and then start dropping back down. The heat also blows “warm” but not by any...

    Volkswagen Passat B5 Discussion
    The nozzle on top of the coolant tank broke off as I was moving the tank out of the way to disconnect some sensors. Attached is a stock picture of the tank with the area that broke circled in red. There's about a 1/4in piece left that's reinforced with plastic bars on the top and bottom and that...
  10. Broken Coolant Tank

    Volkswagen Passat B5 Discussion
    Hey guys! Just wanted to share this little bit of breakdown genius I had yesterday. We all know our cars are getting older and parts need replacing...especially those plastic parts that are subjected to extreme heat. Well, it's been hot in Florida the last few days...REALLY hot. Yesterday, I...
  11. What are the possible causes of loss of coolant?

    Volkswagen Passat B5 Discussion
    Since a few days I noticed coolant loss in front of the car (passenger side). Could this leak possibly be from the o-ring of the temp sensor in the lower radiator hose (per AndreasPassat)? If so, where/how exactly should I look for it? Or could it also be from the turbo coolant lines (per...
  12. Loss of coolant

    Volkswagen Passat B5 Discussion
    2005 Passat dumps coolant out when turned off after running on highway for about an hour and then driving around town for a bit. It appears to come from the passenger side. It does not leak at any other time.
  13. Dumping coolant out the back of motor

    Volkswagen Passat B5 Discussion
    04' V6 30v Yesterday I noticed steaming coolant leaking. Opened the hood and it was coming from the rear of the motor. Couldn't see from the top where it was coming from. Got underneath and it was dumping on the top of auto trans housing. Still couldn't see from where. I have researched it and...
  14. electrical connector to coolant recovery tank

    Volkswagen Passat B5 Discussion
    EDIT: If anyone is interested, ECS has 813 972 923, which looks like an updated, upgraded, or maybe just retrofit, version, $24. This one looks like you could insert the ends of the old wires and secure them into the new housing. EDIT: It gets better -- the 1996 A4 takes coolant tank...

    Volkswagen Passat B7 Discussion
    I'm new to VW, just got a CPO 2015 Passat, 1.8T, auto. It has 25k miles and had it for 2 weeks. I noticed from day one, when I shut off the car after driving, I notice a coolant smell coming from the front of the car. I never notice the smell inside the car with the heater on so that's kind of...
  16. How to "fool" the ECM while removing the coolant tank. B5 1.8T AWM engine

    B5 Garage
    It has a 3 pin connector and I would think that probably there is already cooked by someone in the forum to be able to stop the ECM from panic attacks when sees no coolant in the tank. Now working with the engine speed sensor and removing also the oil filter. The filter definitely will go back...
  17. Misfires after coolant flange replacement

    Volkswagen Passat B5 Discussion
    This weekend I had a coolant leak out of back of the head and fixed the coolant flange. I used some RTV sealant so I let the car sit overnight before refilling it here today. When I started it up it misfired a bit and had engine codes saying misfire in cylinder #2 and after a couple seconds it...
  18. Changed the turbocharger coolant hose (w/o taking out the turbocharger)

    Volkswagen Passat B5 Discussion
    Hi, My 2002 1,8T (AWM) Passat Wagon had developed a coolant leak which I finally tracked down to a disintegrating turbocharger coolant hose. Here a picture of the hose for reference: The location of this hose makes it very difficult to access it. I took out the airbox and hoses attached to...

    B5 Garage
    Hi all, 2001.5 Passat sedan 1.8t AWM, 174,800 miles. I've been working on the timing belt job from hell for the past two weeks. I first thought I had everything done, then I cranked it and the car wouldn't start (it would only crank). After realizing the belt was off 2 teeth I tore it apart...
