Drain petcock valves can be had at most auto parts stores. When you're ready to change it do it on a cold radiator. Do not open the radiator cap. Quickly remove the old valve and install the new one and you'll not make a big mess with antifreeze leaking out.

2000 GMC Sierra SLE 5.3L overheating replaced the water pump, thermostat, fan clutch, & flushed radiator and its still overheating


here are 8 reasons a vehicle over heats. coolant level is low, you have a leak in cooling system, the cooling system may have trapped air inside, the radiator cooling fan is not working, radiator core has become plugged, bad thermostat, or bad water pump, or Your radiator cap needs to be replaced. Good-Day! this is mostly all problems with over heating. if it is a bad head gasket, you will see white smoke from tail pipe. thats because coolant is entering cylinders. as for the radiator cap have a parts store pressure test the cooling system, if they do it.

Peacock valve leak


It's called petcock, and don't ask me why. On the radiator? Some have an O-ring, some just seal after tightening enough. You will have to investigate it. Might be able to wrap some Teflon tape around it and stop the leaking. If the threads are stripped where the valve goes in , either a new unit or figure out a good way to permanently plug it. When you need to drain the radiator, just pull off the bottom hose.

Sounds like a problem with one of the fittings for the cooler lines.
The pipe threads could be stripped or not sealing.

I HAVE ANITFREEZE LEAKS FROM MY 2000 CHEVY S10 BLAZER. IT'S HARD TO TELL BUT THE LEAK SEEMS TO BE COMING FROM UNDER THE MOTOR RATHER THAN FROM THE RADIATOR OR ANY HOSE I CAN SEE.


a common V6 failure is the intake manifold gasket. coolant will usually leak behind the water pump on the drivers side, however it can leak at other locations on the intake manifold gasket.

coolant leaks from other areas include the heater core, hoses, expansion plugs, trans cooler, and coolant overflow tank.

Loosing small amount of coolant (about a cup) every few days in my 1995 GMC yukon. I lost coolant from a leak in the radiator and the engine overheated. Now the temp gauge constantly goes back and forth...


i hate to be the bear of bad news but do a head gasket check . most likely your head gasket is leaking a small amount and its getting burned off.

Ihave a 2000 gmc sierra that has a oil leak down


check for 2 steel cooling lines going to the radiator for leaks at the transmission....but more than likely the oil is coming from the valve covers...if you fix it use the rubber gaskets. if it doesn't leak much just hose the tranny once in a while for it is a rough and it is expensive undertaking at a garage.....it pro is not the rear main seal-which is also not a picnic....keep a check on you eng oil level.....luck to you

2000 blazer ls heater problem. Changed thermostat still no heat. is there a shut off valve thats likely or maybe a plugged core


I'm not sure if you heater control valve is vaccuum operated or if it cable operated. If it is vaccuum operated the valve could be bad or you have a vaccuum leak to the valve. If your valve is cable operated then you most likely have a clogged heater core. Please rate my answer.

How to replace radiator


generally, you look on top of the radiator and remove a plastic cover , depending on the car again, you might have to remove a fan shroud,or the fan if its mechanical, next step has to be with the engine cold, drain the radiator, it has a peacock (drain valve) located on either drivers side or passengers side on the bottom of the radiator. make sure you drain it into a container and not the street, dogs like antifreeze and will drink it and die. once the antifreeze is drained proceed to remove the large upper hose and bottom hose that go into the radiator, it might be attached with a pressure clamp (take off with pliers) or a screw on clamp(with a flat blade screwdriver).
