Question about Cars & Trucks

1 Answer

My 2000 jetta is leaking coolant , it only does this when i turn it off after a 10-20 min drive(im guessing this leak is somewhere within the heating core, since i cant find where that water is going , all i see is the container draining), also after 10 mins driving it the car will start over heating i have to stop and let it cool down , . i also noticed cold/not hot enough air blows when having the air conditioner set on hot. i have too fill the coolant up everytime i turn off the car after a 10 min drive any ideas of what is going on?:(

SOURCE: 2000 jetta doesn't blow cool or cold air out,of the a/c.

yes, after 9 years it needs to be recharged. Have a shop with a good reputation do it. Dont go cheap. It should hooked up to a machine so you can see how much leaked out,and test for leaks. shouldnt be more than $100

SOURCE: 91 toyota 4x4 22re overheats on highway, but not at idle.

original issue sounded like thermostat but now that you have lost power i would have to say thermostat, blown head gasket, and warped head

to check thermostat find and remove place in pot of boiling water the see if it opens, then to ice water to check if closes.


the only way i know to check headgasket and head is to check oil and water. oil will have water in it, and water iw have oil in it

SOURCE: 2000 Xterra intermentantly overheats

sounds more like the thermostat may be failing. generally a water pump starts leaking out of the "weep" hole in the casting before it quits. just look at the front of the water pump for a greenish streak or an obvious leak.
if you also suspect you heater core may be getting plugged now would be a good time to back flush it to get rid of some of the gunk.

SOURCE: Air, no heat '98 Astro. No leaks, engine

It sounds to me that you may have 2 problems. 1). Air Lock in the Heater Core. 2). Inactive Heat Damper in the Plenum.

But since you state that the Heater Hoses do not get warm that is indicative of an Air Lock in the Heater Core. This is a relatively simple fix. It is best performed COLD but requires a method of pressurizing the Cooling System. All reputable Auto Parts stores Sell and/or Rent Pumps that temporarily replace the Radiator Pressure Cap for Leak tests and curing Air Lock. The Collant Level must be filled FULL then pressurized and then loosening the Highest Heater Hose at the Firewall so that Air and a Small Amount of Coolant escapes. Once all the Air has escaped tighten the Heater Hose Clamp, remove the Pressure Pump, Restore the Collant Level to FULL, re-install the Pressure Cap and Start the Engine. As it Warms up you should be able to feel coolant running through the Heater Hoses and they should become warm.

Jetta 4 2.3 v5 heater does not work,only blows cold air


Hi, if the temperature gauge read zero then the thermostat is gone.
If it's just no heat and the gauge on the dash is reading normal coolant temperature then it may be the Coolant Temperature Sensor. If the heater core was gone there should be a leak inside the car somewhere. Hope this helps

Leaking engine coolant. the coolant eventually all leaks out and car over heats.


Does the leak show up on the ground when you are parked with the engine running or stopped.
Determine where it's leaking from. Hose? near fire wall, near radiator. Water pump will leak when it's worn.
Can you smell it when you're inside the car? heater core.

my '01 Jetta had a similar problem. I could always smell coolant and the bottle was always low. I crawled under the car and there it was..a caked on mess of pink antifreeze. There is a plastic intersection 3 way valve where the coolant temp sensor resides. it has 2 bolts and a rubber o-ring. Because it is plastic, it cracks. it drips down onto areas which are really not visible from above and then sizzles and melts onto areas under the engine. The part was only about $25, took 30 min to install and my problem is now fixed. Air was getting into the system through the small crack in the valve further complicating the system operation.

Oil leak somewhere abouve the starter.


It could be transmission fluid. This can leak if not sealed off and they smell similar. If you can get some of that leak on the ground and a good amount, put water onto it. If it turns pink it's transmission fluid. If it stays black the oil line may run under there somewhere. Don't really know about them German cars.

I have a 89 jetta gas. Im losing coolant somewhere and it overheats. But i cant find any leaks (except a little oil). Please help


Are you getting a lot of steam/condensation from the tail pipe? Is it more visible when the engine is hot? If so you need to have the coolant tested for signs of exhaust gases as it may be the head gasket has failed.
