so my dads car is leaking coolant. but im not sure if its the thermostat or the coolant pump? it is leaking from the side of the engine with the timing belt and serpentine belt. is that the coolant pump or the thermostat (this is my fathers car so i can only describe what he has told me tell i look at it tomorrow). well let me know guys so i can get it replaced since me and him are trading cars this week. thanks.

I think that's the pump, wait for someone else to reply though...

First guess is Pump as well.

Have a feel about the bottom of the pulleys to see if they are lashed in Coolant. Remember coolant will flow across surfaces under the engine via gravity etc,... so it could be leaking at the other side!!

ENGINE OFF !!

if its a 1.5 sohc then this could be confused with a thermostate housing leak... the housing is placed above the water pump and when the thermostate gasket deterorates the housing leaks and coolant drops right on the water pump till it hit the ground... the untraned eye might confuse this with a water pump leak so be careful during the inspection.

if you want to test the leak, turn on the engine and let it idle till the coolant fans kick on, once they did that tun off the engine... at this point the engine is very hot and the cooling system is not defusing the heat through the radiator as the cooling fans are off so the water temp keeps rising and put more pressure on your cooling system and leaks become more and more evedent.

don't worry, that will not hurt the car at all as the reservoir cap got a blow off valve to release extra pressure if too much pressure builds up inside the cooling system. i also heard that some lanoses keep the cooling fans running even with the ignition off so if you got that watch out for your fingers, if the fans kicked on they can cut your fingers.
