check to see if the thermostat is hung open or your temperature sensor for your fan is out and causing your fan on your radiator to run continuously when key is on.
it's getting too cool, really
Dex-cool is recommended to be changed every 5 years.
whaT KIND OF COOLANT DO I PUT IN MY 2001 PONTIAC SUNFIRE Generally, the GM model vehicles, or is this case, the sunfire, use a specific kind of coolant called DEX-cool extended life engine coolant. It is orange-ish in color and most of the time GM specific. i have a 01 sunfire, 2.2 liter myself, and on my car frame, i have a sticker that says "Use only DEX-cool engine coolant....". Hope this helps!
On a 2002 Pontiac Sunfire with a 2.2-liter engine, the thermostat is located on the engine's cylinder head, at the end of the upper radiator hose. To access it, you typically need to remove the upper radiator hose and the thermostat housing. Once the housing is removed, you can replace the thermostat. Always ensure the engine is cool before attempting any repairs.
Old age and vibration, I'd guess. All of mine were out too. The PONTIAC on the trunk lid wouldn't light up. I replaced the bulbs and now it does. For what it's worth, it's Way Cool when the PONTIAC does light up!
The map sensor on a 2003 Pontiac Sunfire is located on the intake manifold, typically near the throttle body. It may be mounted directly on the manifold or attached to a nearby bracket. To access it, you may need to remove some engine covers or components for better visibility. Always ensure the engine is off and cool before attempting to locate or work on the sensor.
To adjust the timing chain on a Pontiac Sunfire 2.2, first ensure the engine is off and cool. Remove the timing chain cover to access the timing chain and gears. Align the timing marks on the crankshaft and camshaft sprockets to the specified positions, and if necessary, replace the tensioner or adjust it to ensure proper tension. Reassemble the cover and ensure all components are securely fastened before starting the engine.
To replace the radiator inlet tube on a 2000 Pontiac Sunfire, first, ensure the engine is cool and disconnect the negative battery terminal. Drain the coolant from the radiator, then remove any components obstructing access to the inlet tube, such as the air intake or hoses. Unscrew the old inlet tube and replace it with the new one, ensuring a tight fit, then reassemble any removed parts and refill the cooling system with coolant. Finally, reconnect the battery and check for leaks by running the engine.

To change the thermostat in a 1995 Pontiac Sunfire, begin by ensuring the engine is cool, then disconnect the negative battery cable. Drain the coolant from the radiator and remove the upper radiator hose connected to the thermostat housing. Unbolt the thermostat housing, remove the old thermostat, and clean the mating surfaces before installing the new thermostat along with a new gasket. Reassemble the housing, reconnect the hose, refill the coolant, and reconnect the battery.
To change the radiator hose on a 2000 Pontiac Sunfire, first ensure the engine is cool and then relieve any pressure in the cooling system by removing the radiator cap. Use a pair of pliers to loosen the hose clamps at both ends of the hose and carefully slide them off. Remove the old hose and replace it with a new one, securing it with the clamps. Finally, refill the coolant if necessary, and check for leaks after starting the engine.
The EGR (Exhaust Gas Recirculation) valve on a 2000 Pontiac Sunfire with a 2.2L engine (VIN 4) is located on the intake manifold, typically near the throttle body. It is a cylindrical component connected to the exhaust system and has a vacuum line and electrical connector attached. To access it easily, you may need to remove any obstacles such as the air intake duct or engine cover. Always ensure the engine is cool and disconnected from the battery before attempting any repairs.
