Question about 2000 Volkswagen Jetta TDI

1 Answer

Temperature fluctuates In the summer the engine gets real hot. If I idle for more than 2 minutes it enters the red zone. As soon as I start driving, the temp falls back to 190. In the winter the engine never gets up to 190. If I turn on the heat, the temp falls lower. No warning lights have appeared on my dash. I do need to add a little antifreeze/coolant about every 2 weeks. I have never noticed a puddle below the car. In the summer I don't use AC because when I do periodically black smoke is forced out of the muffler.

Why does my temperature gauge keep going up and down


An accurate temperature gauge will always fluctuate because the temperature in the engine fluctuates.

Usually the only time this is really noticeable is when the engine has been working hard and suddenly has to wait at a junction or similar and the gauge can rise considerably.

You didn't mention by how much the gauge fluctuates?
As long as it remains approximately in the normal zone it is acceptable but if it climbs into the hot zone or falls into the cold zone it is not acceptable and the cause should be investigated as soon as possible.

Will not restart


Sounds like vapor lock. This is when the fuel turns into a vapor before reaching the engine (it needs to be in a liquid form). This is usually due to high temperature from the engine and environment. I would have someone check it out.

Mini Cooper temperature gauge goes to red zone when idle


check coolant level could be too low allowing air in the cooling system causing air pocket in engine around the engine coolant sensor.coolant sensor needs to be in hot coolant so it will cause the cooling fan to come on at a set temperature.make sure coolant correct level and the coolant level in the cooling overflow jug should be at full cold mark.the cooling overflow jug should never be empty,if you see empty cooling overflow jug air got in the cooling system so make sure when engine cold every time raise hood make sure cooling overflow jug coolant level at full cold mark.if jug stay empty you have cooling leak.so replace radiator cap,if coolant level all good,i would replace the engine coolant temperature and thermostat.when your car come to a long stop or driving along long line of slow moving traffic the engine coolant blower motor should running if not have vechicle code scan for faulty coolant fan motor control module.or ecm problems.

The temperature gauge fluctuates very close to hot, but only during city driving. While on the freeway, the temperature indicator reads normal. What is your opinion as to the cause and solution to this...


this is normal, the cooling fan of the engine doesn't come on until u are abouut 2/3 of the way to hot zone of gauge, about 225 degrees F. let me kniow if that is the case.

We have a 90 Quattro V8. Last summer I changed


Your V8 Audi has two necessary sensors that malfunction due to their placement in extreme heat on the lower left side of the engine just inside of the header/down pipe connection. They read the flywheel position for the engines computer ECU. The reference sensor is always suspect, but the speed sensor may need to be changed, as well. The wire connectors to the sensors that sit above the FL suspension can be tested, or just replace both sensors to get some quality time with your V8.

1999 Toyota Camry Idle Problems on Hot days


Clean the IAC. Disconnect throttle body air hose and you will see a hole on the bottom of the throttle body just before the butterfly valve. Spray throttle body cleaner down the IAC hole and then let it soak about 1/2 hour. Reconnect hose and run engine about a minute and then repeat this process 2 or more times. Toyota engines from 1997-2005 commonly have the IAC get cruded up with carbon as early as 35,000 miles. This is a sImple and cheap repair that many repair shops don't want you to know.
