Hi. It is a well known problem on VWs you need to let all the air out , your car should have a valve to do this but if you can not find it try leaving the antefrezze cap of and watch for bubles coming out the water ( with the engine runing ,, ) cold

Going up hill lack of power and smoke pulled over then started to go again didnt do it again on level ground what it might be


It will lack lots of power going up hill, especially if its a really steep one and you keep it in drive. Make sure you downshift to second, or fist if its really steep.

My 01 Pontiac Montana is trying to overheat at high power


If your vehicle doesn't actually overheat, just getting hot, I think that's the normal behaviour for these cars. My 03 AWD behaves the same way. When driving uphill, especialy when towing, the temperature rises close to the red marking, but I have never experienced it overheating. I think that the temperature has to rise much over the normal driving temperature to activate the two electric fans.

A motorhome with Hp of a nissan z24 engine, can it climb steep altitudes? i.e. Andes mountains or the weight of the motorhome would be too much for the engine?


A few ideas. 1) Try the motor home where you are now and see. Find some REALLY steep hills or something and try it out.
2) If it is an automatic transmission, you may need to purchase a "transmission cooler" kit to add on before you try mountain climbing.
3) If it is a stick shift, take along another clutch disc and pressure plate and throwout bearing in case you burn yours up.
4) And remember, cars and trucks that normally operate at sea level will not do well in high mountains. They need to have the timing and/or carburetor set for high altitudes.
5) Many countries outside the USA have different octane ratings on their gasoline, you will need to take along the stuff to set your engine to the octane rating of the gas you buy.

Overheating


Have you checked to see if the cooling fans are coming on? Is the coolant level low? Could also be a weak water pump. Does the temperature gauge appear to work normally or do you go from low temp to high temp and then back to low rather quickly? If so, it could be a bad thermostat.

When do you use the over drive?


leave it on all the time is better miles per gallon you can turn it off if you are going on a steep hill and you accelerate and down shifts and as soon as you let go a little it shifts back up you can turn it off to keep it at a lower transmission gear its really like down shifting when is off..

1986 Pontiac Trans Am Overheating


Its overheating when you go up long hills because the engine is not getting adaquete air in the system. The radiator is angled to get optimal air a certain way. It may overheat but you shouldn't start seeing smoke.

2009 Toyota Camry problems


All Toyota auto trans cars downshift when descending a hill when you tap the brake. This is called "Downhill Shift Logic"; what this is for is to eliminate the double shift when you come to the bottom of a hill and then accelerate. Normal condition. Usually happens above 38 MPH.
Also: The cruise will accelerate when going uphill. Normal condition.Plus: The cruise will not disengage back to the set MPH after you top the hill. Toyota recommends to disengage the cruise when encountering steep terrain.

Engine overheats on Pontiac 2002 GP


Check the catalytic converter. If it is clogged, it will reduce your your power and increase the temp of the car, especially on steep inclines.
