94 Pontiac firebird only overheats when it sits for a long time?
Could any of several problems - Radiator beginning to plug - flush it. Water pump beginning to fail - replace it. Water pump belt loose - tighten it. Low cooland level - fill it.

If the water pump needs to be changed due to a leak in the cooland does it mean a gasket has blown as well?
If you're referring to the water pump gasket, and, if you're changing a faulty water pump, a gasket should come with it and also needs to be changed (Use the grey Permatex gasket sealant on the new gasket). If you're referring to the head gasket - not necessarily.

You repleace water pump termostat temperature sensor and your temperature gauge go from 210 to 260 almas hover heat is when the fas star working and two relay go hot mi car is 1997 Pontiac transport 3?
Pontiac Transprots are bad for having the intake gasket go... it can cause overheating. That's what was wrong with mine, but it was about 13 hours of work replacing it and I'm pretty familiar with minivans. It can also be the head gasket, if it is it will usually burn coolant, and or the oil will be milky coloured, and or the cooland will be oily, and or the compression will be bad and or the engine will idle poorly/ use too much gas. Good luck

What is wrong if cold air blows out when heater is on?
I assume your car heater is blowing cold air, when the heater is on. It seems that, you have air on your coolant. that air pockets blocks the cooland to travel through your heater. it may be a sign of a bigger problem such as blown head gasket in the old cars, such acura legend

Which coolant antifreeze do you use for jeep grand Cherokee?
Read Haynes 1993-2004 Antifreeze/cooland - general information: Warning 1: Use only "ethylene-glocol" (green/blue). Do NOT use propylene-glycol (yellow/red). From 2002 long-life-special-glycol (HOAT) are used, and can not be mixed with other types of antifreeze.

What to do when coolant light comes on?
If your asking this question its probably a good idea that you bring it into the shop to have the levels checked. DO NOT try to check your own coolant when the engine is still hot, this will send coolant bursting into the air. This is if you have any lol. Check your cars temperature gauge while your drive, if its starts getting warmer than normal then you need a cooland change.
How do you replace the cylinder head gasket on a 2000 vw jetta 1.8 turbo?
to replace the cylinder head you should get a chiltons book for your year make and model of your vehicle. If you have never replaced a head gasket before you should take care to make sure the timing on the camshaft and crankshaft are set to top dead center before removing the cylinder head because most volkswagons have an interferance engine which means the cam and crank must be timed properly or could cause cylinder valve damage. Take cylinder head to a machine shop and have them check the cylinder head for warpage with a straight edge after you have cleaned off the gasket and any material on the head. If cylinder head needs resurfacing, make sure the machine shop does this. Follow directions carefully to retorque the head down (if needed replace head bolts if they are torque to yield bolts). Make sure you repair the problem that caused the cylinder head gasket to leak. This problem could be anything from a leak to bad thermostat, or even a bad water pump. When i replace a head gasket I always replace the water pump and thermostat and flush the radiator, heater core and change the oil twice before driving. Most newer volkswagon vehicles have an air bleed procedure to get the air out of the cooland and to condition vehicle for proper coolant flow. check procedures and follow exaclty.
