My 2000 Jetta TDI blows cold air while driving. No fun this winter! I would expect a bad thermostat; but I understand if the thermostat is bad a warning light would be lit on the dash. Is that the case?


No, this is not your case. If the thermostat is bad any warning light would be lit on the dash.
First time you might check the thermostat operating.
Heed of antifreeze coolant temperature!!!

The thermostat location for 2000 VW Jetta 1.9 TDI, is on back of the alternator at the bottom side of the bracket.
IMPORTANT: It is NOT necessary to replace the alternator if you want to change the thermostat !!!
Thermostat checking:
1. Cold engine. Start up the engine and watch of the water temp indicator. After first value 60 Celsius Degree you still warm up the engine until the lifter (pointer) reach 80 C deg. (second mark after 60 C deg.). At this time you let engine running at idle speed and check with your hand the thermostat plastic housing and hose temperature in bottom left side of the engine. Heed of alternator driving belt and ventilator fan !!!
2. If the thermostat is good the hose must be cold until the water temp indicator reach almost 90 C deg.
3. The thermostat opening temperature is 87 C deg.
4. If the hose is already warm the thermostat is out of order.

Thermostat location, Part number: 044121113, in german - "Kuehlregle" (Price around $25):

I have a VW jetta mk3 1994 ive had problems with it sine the day ive gotten it 3months ago it ran prety well then one day it kept cutting out on me every time i taped the gas i thought it was a fuel pump...


There are several things that few people know about starting cars in cold weather. 1. Check your battery to make sure it is not rusted, leaking, and has a charge 2. Jump start your battery with another car, even if you believe the battery is good, this often times will still start your car. 3. If your engine is cold, and you have an older car, ensure to get your fuel lines to the engine flushed or have fuel injection service performed 4. The engine tends to warp the same way wood does during the extreme cold, do not be afraid to continue trying to warm up the engine by constant cranks with it is cold out. Your not going to hurt the car, the worse that could happen is too much fuel will enter the carborator and cause flooding in the system to occur. Wait 20 minutes if this happens and start to crank again 5. Bad spark plugs are a major reason why many cars take a very long time to start 6. Please have your spark plugs removed and exchanged for new ones. Over time, spark plugs become fowled and prevent the car from starting even thou you hear cranking!!!

Temp light flashing after starting.outside temp.-17


Extreme cold weather is causing coolant to contract and fluid level is reading low level ... After starting with the engine warm the temp light should go off due to expansion of the coolant ... Solution: Add a small amount of coolant to compensate for cold weather contraction. Good luck!
