On my 99 sunfire it is directly to the back/side of the alternator; very easy to spot
A 1996 Pontiac Sunfire uses Dexcool coolant. This should only be mixed with distilled water, never tap water. Replace the coolant every 2 years or as needed.
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!
Coolant is all pretty much the same from manufacturer to manufacturer. Check your owner's manual to find out the right mixture for your Sunfire
Around 90-100C or 195-210F, if it's running any warmer than that try doing a coolant flush
it's getting too cool, really
location of 2003 cadillac coolant temperature sensor
location for 2003 chevy trailblazer coolant temperature sensor
Fill your coolant reservoir and the light should turn off. Do it soon or your engine may over heat.
where is the coolant temperature sensor locate
more likely to be a faulty coolant sensor or the thermostat is faulty and staying open
heater core has a leak replace heater core
In answer to your question the coolant temperature sensor on a 2000 Pontiac grand am with a 3.4L engine, is located on the rear of the engine above the flywheel. It is located just behind the what I believe is the alternator.
