Greetings To All

I have a overheating problem and have replaced just about every part of the cooling system waterpump, radiator, lower & upper hoses, temp sensor, thermostat, Waterpump Pulley Tensioner belt, fresh Flush / fills of "50/50 Dexcool".
But the system keep overheating and both hoses are so swollen each time it overheats. Someone pointed out that everything was replaced, accept the "Waterpump Pulley Tensioner Assy", which doesn't appear to be having any problem. I'm low on cash and need the car. Could someone Please Explain what this part or how important it is. Should There Be Any Other Parts To Consider.
Thank You In Advance.

It is unlikely that your W/P belt tensioner is causing your overheat, unless you are throwing the belt and the pump is not turning. I would not go any further without having the cooling system tested for the presence of combustion gases, indicating an internal leak.

Greetings GStacey

Well looked at the belt, the tensioner, and waterpump. Started the car and saw that the belt was bad, cracking and slipping not spinning waterpump pulley too well.

Decided to change out belt & tensioner, waterpump was only 27-days old. Got everything in place, car ran fine for a day. Then Disaster, don't know how or what happened, but car when from 196 to 255 within about 12-seconds. Stop to look, The Water Pump Pulley assy from the engine, the tensioner pulley, and the dog-gone waterpump pulley all 'Destroyed. DOG. What A Damn Nigthmare. Cars been parked. Now, some are telling me to replace all of the parts and double check everything. In any case, Thanks a lot for your valuable advise, it lead me to the problem. Don't know what else to do, but I need the car.
"Have A Good One".
