Well, my car is a 97 Pontiac Sunfire, but I've heard it's about the same. Right now, I have to replace the water pump in MY car. My first indication was it continually was losing coolant and the light indicating low coolant levels kept popping on, no matter how much I added. I took it in and had it tested, and they told me it was the water pump.
Usually a water pump on any car will start screaming just before the bearings give out totally. Used to be that you could regularly lubricate a water pump through a little lubricant hole, but I doubt you can do that on modern ones.
Another way of telling is if the weep hole on the water pump is leaking fluid.
look at peep ho;e pn water [ump.if theres a discharge, replace it, seal weht bad
Off the water pump
Pay a mechanic to replace it
A lack of water in your cooling system will cause your 2002 Pontiac Sunfire to overheat. A malfunctioning thermostat can also cause it to overheat.
Take it out and put a new one in!
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.
Is located in side right under manifold
Usually right above and in line with the crankshaft pulley
I have a 98 GT it was underneath yhe car just follow the water hose
it's in the belt path and has sort of a snout behind the pulley. It's back near the tensioner.
Bad trunk lid gasket. The gasket may have come loose or got cut.
The red water symbol is an indication that the water is overheating. The red battery symbol is a indication the charging system is not working.
To change the thermostat on a sunfire,look for the largest hose going into the water pump.Should be to the left as you look down at your fan.There should be a clamp holding the hose on. Remove the hose and look in the hole that the hose was pulled out of. It will be seated right there.If you need a pic. I have a manual and I can email it to anyone .
