heater core has a leak replace heater core
If its the little "elbow" that comes out of the fire wall on the engine side then it means the heatercore is leaking. This is a drain hose for the ac and if the heater core leaks it drains thru this tube
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.
on the firewall side of the engine...passenger side
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
it's getting too cool, really
If the Coolent is leaking I strongley suggest you take the car to the dealer or a dealer to get it fixed because if it leaks more it can cause trouble.
1200 $ for a new head and instalation
On my 99 sunfire it is directly to the back/side of the alternator; very easy to spot
Have you checked the power steering pressure line?
Fill your coolant reservoir and the light should turn off. Do it soon or your engine may over heat.
Leaking hose? Defective thermostat housing or bad thermostat gasket? Bad water pump or gasket? Leak in radiator? Leak at heater core? Leak at head gasket? Coolant recovery tank?
