    I DON'T SMELL ANY EXHAUST IN THE COOLANT, ALL OF MY PROBLEMS SEEMED TO DOMINO AFTER I CHANGED MY THERMOSTAT, COULD IT BE FAULTY? MY BUG RAN LIKE A CHAMP UNTIL THE THERMOSTAT WAS CHANGED BUT I DID NOT KNOW ABOUT BLEEDING THE AIR HOW DO I DO THAT? I WILL TRY CHANGING THE FUSES BUT THE CHILTON FAN TEST PROVED THE FANS TO BE OK OTHER THEN THEY RAN WHEN I PULLED THAT 1 FUSE OUT WHICH CONFUSED ME.?

    REPLACED THE THERMOSTAT 1ST TIME BECAUSE OF OVERHEATING LIGHT COMING ON . WHEN THE VW KEPT OVERFLOWING FROM THE EXPANTION TANK REPLACED THE THERMOSTAT AGAIN BELIEVING IT WAS FAULTY BUT THE PROBLEM CONTINUES. I BELIEVE NOW THERE IS A BLOCKAGE AND AM GOING TO FLUSH IT TOMARROW. OIL DIP STICK CAN SMELL GASSY COULD THIS MEAN A VALVE? OR AM I BLEEDING THE SYSTEM WRONG?

In the fan circuit...You have a temp switch screwed on the radiator, a fuze and a relay in the fuze box plus a fan.  Swap the relay with another relay, replace the fuze.  The other fan should come on when the a/c is turned on.  If you fix the fans and it still overheats, you may have a BLOWN HEAD GASKET.  ALSO ARE YOU BLEEDING THE AIR FROM THE SYSTEM?  DO YOU SMELL EXHAUST IN THE COOLANT?

    could you have installed the thermostat backwards?  There should be a bleed screw on the thermostat housing.  Also why did you change the thermostat?

    it's a labor intensive repair, you need to remove the upper 1/2 of the engine.

I have 2002 vw jetta wagon and it keeps over heating. We have changed the thermostat fuses relays and the heater core connector. We think the water pump is working fine because it has pressure and...


Pressure is not a good indicator of water pump operation. Pressure in the cooling system comes from the heating of the water and its expansion. Jettas come from the factory with plastic impellers on their water pumps. These have a tendency to break and fail, causing overheating issues. Most aftermarket pumps have metal impellers to prevent this from happening. I would seriously consider having the water pump replaced, especially if it is original and you have more than say 60K miles on the car. It's due for a change anyway and may save you your engine. See what this guy had to say about his Jetta.....

My 2002 buick century overheats and has no heat


Possible trapped in system. Bleed system, should have two small screw bleeders, one in front of left valve cover on pipe behind water pump and the other on coolant pipe outlet as you follow upper rad. hose towards engine. Engine cool, remove rad cap, open both bleed screws and fill rad until coolant flows free out both bleed ports. close both bleed screws, rad cap off, start engine and let idle until upper hose is hot to touch , shut off, let it cool down for 20 minutes, top up rad and install cap. restart car ,drive and check.

2001 VW Beetle heater not heating.


If both your heater hoses are hot, the heater core is circulating fluid. If only one is hot, and one is cool-then the core is plugged or has an air block, or a valve in the heater line is closed if that applies.
If the engine stays at normal operating temperature, doesn't overheat at all, there should not be a problem with the water pump.

The problem may be with the doors in the heater case not operating properly.

Check to make sure that the rubber o-ring going into the heater core located under the hood on the passenger side does not need replaced. Also check the water pump, these are both very common problems with volkswagen.

you dont have to bleed the water it automatically takes out the air when it runs and the thermostat valve opens check the level again after a run of 5 miles or when the temp is in the middle

remember not to check when the engine is hot

Over heating


as stated, gotta be the thermostat... when the water reaches a certain temp this valve must open to allow coolant to flow thru the radiator or the water in the engine will get too hot and cause significant long term damage. It's good that you pull over immediately and let your engine cool off. A good emergency remedy to get the car to a safe place or a repair facility, is to run the heater at full blast. effectively using your heater core as a radiator. not ideal but will get a you a few more miles down the road.

04 civic heater blows cold air at idle


you should have hot water on all rad. hoses when the motor is running at a norm. temp. the water is not going through the heater core like it should. you have cutoff valve bad low water are a stopped heater.try a hoter thermostat if none of the above are true.
