STOP OVERHEATING!! new thermostat new radiator cap

I've put in one treatment of K&W head gasket sealer in it
and tht seemed to help for about 2 days.. But anyways
when i unscrew the bleeders on the car no fluid comes out

How many miles on engine? Have you tried a compression test to determine if head gaskets are okay? You can also try a pressure test on the cooling system, make sure all hoses and connections are good. Go to Youtube for signs of a bad water pump, it will give you some things to look for. If you're still unsure let a mechanic look at it.

Hi ken the rendezvous has approximately 135xxx on it .. I haven't done a compession check on it .. As I'm pretty sure the head gasket is blown on it from the amounts of smoke / haze put out by the exhaust.. And also the oil level seems to be quite overfilled/runny and the tell tale sign of the milky green oil fill cap!!! & also I'm unsure of how to even go about tht with it being FWD?? and ok I will head on over to youtube now.. I also just went out and purchased another treatment of K&W head gasket sealer ... I guess we will see if this stuff works as good as it says it does??
