Question about Cars & Trucks
I replaced thermostat but coolant seems to be leaking from the pulley side of the engine? Is this a gasket?
You don't say what make and model you have, but on many engines now, the water pump is behind the timing cover which is the same cover behind the serpentine pulleys. So it is probable your water pump is leaking in there, and coolant escaping from behind the cover. It is not usually economic to overhaul the pump itself.
If your engine has a timing belt, I'd advise changing that too as it has to come off.

when installing new o-ring on tube, lubricate o-ring and stick it in water pump. Then pull pressure back on tube and then tighten hold down clamp. problem solved

i have a 2005 1.8 nissan sentra.i rplaced the radiator becuause it was leaking.so when i did i took it for a test drive and the needle went to hot then back down to middle ways between the C & H BACK IN FORTH.so i replaced the thermostat. now as far as i can tell it is staying in the middle of C & H. i can't feel no water though cerulating through the top or bottom hose of the radiator. so now that i told you what i done so far my question is???? ( my heater is not working in the car it is blowing out cold air & i left the car runnng for about 45 min. even took it up and down the road.still cold air.what do you think i need to do?????????? )

Hi, Sounds like you have tried about everything. Ok the aux. coolant switch is for the electric pump for the heater core will not cause an over heating condition just a longer warm up of the heater core. Has the cooling system been bleed properly if there is a trapped air pocket it will not let coolant circulate. Was the new thermostat installed correctly? They have a vent that needs to be towards the top or they trap air on the back side and cant take an accurate reading to open and close. Other areas to look at would be proper operation of the fan clutch, if they fail they can cause the fan to not lock up properly and supply enough air movement through the radiator. The aux. electric fans and their temp switches do you hear them coming on are they coming on at the right temp.
