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
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.
Pay a mechanic to replace it
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.
Take it out and put a new one in!
Is located in side right under manifold
I have a 98 GT it was underneath yhe car just follow the water hose
Usually right above and in line with the crankshaft pulley
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.
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 . My email is: firstname.lastname@example.org
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.
I'd guess 4 hours of labor would about cover the job. It's worth it.
the water gets into the combustion chamber and comes out through the exhaust pipe as a vapor
There will be an input of some kind
generally, if you know that the pump is bad or failing, replace it. Repairing it is rarely an option. That's why there's a core charge on them. They are returned for factory refurbishment.
It's very easy to see the pump and you will see signs of leakage under it.
I have a water leak in my 2004 Pontiac Montana between the drivers door and theseat,I was told it is the rubber gasket-that's in the floor,where the water drains,outside the Van,is this going to be a big job to repair???
Answerwater pump for a 98 sunfire is located with the timing belt can be a job. have to remove front of motor. enj. mount ect. More: Unless the 98 is much different from my 96, the water pump has nothing to do with the timing belt. Also, there is no need to remove an engine mount bolt.You should be able to loosen the belt tensioner enough to get the belt on and off the pump pulley.
This sounds like a classic case of a blown head gasket. You can look for signs of leaks where the head meets the block, but the best test is a compression test. Replacing the head gasket is a fairly big job. If you decide to do it yourself, you'll want a Haynes or Chilton manual to guide you through the job. FriPilot
The coolant container in my '96, has a mark on the front end, which says "Full Cold". When the car is cold, fill with a 50/50 coolant and water mix. FriPilot
