Did you change the thermostat? If not it may be the cause. You can check the thermostat by removing it and immersing it in hot water. If it is working it will open. The thermostat is usually located under the upper radiator hose.

SOURCE: engine overheating there is no coolant leak but it overheats and

1st it is imperative that that cooloant mixture is correct. once you have the correct mixture have the thermostat replaced. Or just have a mechanic replace the thermostst and they will balance the coolant to water mixrure

SOURCE: 2002 audi tt overheating

It does sound like the dash pod is faulty. I have had dashes pass cycle tests but turn out to be faulty.
Check when the car is hot, that when you key off and then key just the ignition on that the gauges (fuel and temperature) move slowly and smoothly up to there correct position. If they move very quickly, almost instantly, to there position then this is a sign of a faulty dash.
Let me know the out come.

SOURCE: '97 A4 1.8T, coolant leak resulted in brief overheat,leak fixed,diag.code now shows #2 cyl.missing (badly), compression good,injectors good,coils/plugs good,missing badly,could the brief overheat have

did the car over heat for long?
there could possibly be damage to your head like warping due to overheating and blowing a head gasket or something along those lines .
first check the oil dipstick is it milky?
then check the coolant is it oily?
and when it is running is it blowing any white smoke?
if you replaced the plugs and it is misfiring did you plug the wire all the way back on the plugs if not then the problem is a plug wire being loose and loosing connection with the plug.
sounds like a simple fix if you don't have water in your oil or white smoke coming out the exhaust.
troubleshooting it can be a bigger job but if you nail the right symptoms down you can corner the problem.
like if it is a coil pack or bad wire switch them with another one and see if the problem follows the wire or coil pack.for instance take the number one plug wire off and the number two wire off and put the number one wire on number two and see if the number one misfires. if so then the wire is the problem if not then try numbers three and four until you find out which cylinder is the culprit.
good luck and happy hunting.

How do you know if your water pump is working?

A car engine waterpump rarely stops working - the bearings fail and the seals leak sometimes but they usually keep pumping to the end. In over 40 years I have known only one that lost it's impeller.

If the waterpump should stop working there would be no coolant circulation and immediate overheating...

2001 olds silhouette engine overheats

Time for Intake Gaskets and possibly head gaskets, very common problem with these, the intake gaskets go bad and the coolant actually burns in the cylinder and of course the cylinder pumps air into the coolant system because of intake gaskets being bad. :-(

Water pump is bad because overheats when engine is running at low speed, and good at high rev. The water pump impeller can not push the coolant with the required pressure.

Over heating engine. water on floor in cabin. windscreen fogs up after short runs. loss of coolant. strong smell of coolant/rust in cabin. water seems to be entering thru heating ducts.

Soundls like (REALLY LIKE) a broken heater matrix. You can bypass the matrix by pulling the water pipes from either side and joining them with a piece of copper pipe to stop the leak and make the car useable for the time being. You will have to get a new matrix and fit it or have it fitted if you want a heater tho...
Don't let the engine overheat - you'll turn a slightly pricey job into an enormously expensive and time-consuming job if you let it overheat too much.

I heard a squiky noise like some kinda old belt rotating, then it stop. 2 miles later i saw temp rise. i pulled over and antifreeze was splatter from the top of radiator.

Check the radiator hoses for a leak. The splatter was most likely the coolant/anti-freeze leaking from one of the hoses. Loss of coolant would make the temp rise and the engine overheat. If the hoses are good, look for seepage around the waterpump. These are the main causes for coolant loss.

A repair shop said it was the waterpump and

You need to look it over and find the source of the leak.
Coolant loss will cause an overheat and every time that happens you risk an expensive job including total engine loss. Obvilousy no one here can see your engine and tell you where the leak is. If you don't do your own work, have the shop that did the work check it over. Normally shops give at least a 90 day guarantee on their work and therefore if the pump is faulty or there was a problem with the install, they should correct it.
