Engines overheat with no thermostats. Very simply put the water circulation is too fast for the heat to transfer to the air. Water pumps fail from bad bearings and pump seal but for no other reason. So back to basics Refit with a new thermostat put in properly. Have a flow test done on the radiator for blocked cores. have a coolant system pressure test done for leaks and cap failure.. have a compression test done to check for head gasket or cracks.. Check for correct ignition timing and air/ fuel ratio mixture. Run fault codes . when refilling with coolant ensure that all air locks are removed

Do a pressure check of the cooling system, and the radiator cap-you could be blowing fluid out and then over heating-also check the exhaust for white sweet smelling smoke which is burning antifreeze-which could be a leaking head gasket- Denny

SOURCE: i have a 95 chevy lumina. the water pump went bad

It is possible that some water got into the lifters and after it runs for a while, it will quiet down. However it disturbs me that he noticed them being "kinda loose" and did not investigate further while the head was off.
At that time, all he needed to do was reach over and pull the lifter out of it's bore and look to see if the cam end was worn. (if so, it needs a new cam and lifters) Same applies to rocker pivots. if loose, why?
That is no different than doing brakes, seeing a bad hub bearing and ignoring it.
At this point, since it is all together and running, I'd add a quart of marvel oil and hope it clears it up...otherwise the engine will need to come apart again.
They did change the oil after the job was completed?

SOURCE: The cooling fans on my

A bad water pump would have nothing to do with the fans not running. Did you check voltage at the fan? When the fan is suppose to be on (when temp comes up unplug the fan and check voltage on the plug that plugs into the fan. They are notorious for their relays going bad.

Hope this helps! Please Vote!

Sounds like your thermostat is sticking closed at times, not allowing coolant to circulate through the radiator for proper cooling. Replace thermostat.

I have a 1999 chevy lumina and it overheats when i am just idling and the ac is on.

This problem can be caused by a faulty cooling fan, lack of coolant circulation thru the radiator ( bad water pump, partially closed thermostat) or a partially clogged radiator. Make sure the radiator and condenser in front of the radiator are not full of dirt and clogging the air flow also.

I have a 1995 chevy lumina and need to know how to change the thermostat, can you help? What do I have too take off of the car to get to the water pump so that I can change out my thermostat?

You don't remove the water pump to change the thermostat, that's not where it is. It's at the engine end of the upper radiator hose that connects the radiator to the engine. How do you know that you need one? Are you overheating? In a car of that age you could easily have a plugged up radiator, you would want a reverse flush; watch the newspaper ads for a discounted price on that service. If the coolant is dirty, not bright green it will be deteriorated and will overheat. For extra they'll also change the hoses and thermostat. It can add up so shop it around.
