Question about 2005 Buick Rendezvous
Problem with overheating. maybe the head gasket or IM gasket..radiator cannot hold down fluid when car running.keeps coming back out
If it has the 3400 v6, better known as the 3.4litre, this motor was prone to head gasket failures. Antifreeze on spark plugs is a sign of head gasket failure, so is antifreeze in the oil. Have a mechanic put a dye in the cooling system that is detected with a certain light and that will tell you exactly where it's coming from. Headgasket repair is not cheap. May be easier and cheaper to replace the motor. Wish you the best!

THE ANTILOCK BRAKE SYSTEM COULD BE THE CULPRIT HERE. YOU WILL NEED TO TAKE IT TO YOUR LOCAL REPAIR SHOP OR DEALER AND HAVE THEM DO A PRESSURE BLEED ON THE BRAKE SYSTEM. THEY SHOULD ALSO PERFORM AN ABS SYSTEM BLEED WHICH IS DONE WITH THE SCAN TOOL. THIS SHOULD TAKE CARE OF THIS PROBLEM. HOPE THIS HELPS!!

first check to make sure the cooling system is not air bound,takes a while to bleed off the air,try this and get back to me Thanks Ray

If the top hose is hot and the bottom is cold, your definitely not getting circulation. You,ve already done alot of work to this vehicle so you have pretty much answered your own question. About the only thing left is the heater core. Of course, I dont want to be the one to tell you it is definitely the heater core because obviously I am not looking at the vehicle. But If i was a betting man, thats where my money would be.

This is all getting to be pretty bad when no one listens!?
All Buick Rendezvous overheat! It's a badly designed system with no upper engine compartment ventilation! It's one thing to save on mileage with a hot engine but another when it's so hot it burns out all gaskets and seals everywhere! Counter productive to say to least! People are spending tons of money on repairs that are not necessary!
I bought a 2002 Rendezvous knowing full well that I could fix the overheating problem! I got a good deal on the SUV and bought it knowing it was an easy repair! The previous owner spent a bundle on new head-gaskets and still the overheating problem did not leave! I purchased it knowing full well what the problem "was" !
I did an inspection on the (engine compartment) The engine sits quite high in there and the heat of the engine has no escape from the compartment. It's closed off and the engine sits in it's own heat getting hotter and hotter destroying gaskets and all other heat related injuries ! The cooling fans direct the incoming air to the bottom and out below the problem!
My inspection shows trails where the heat did escape around the upper rubber seal at two ends over the engine compartment.. Those very small openings were the only means of heat escape, but not nearly enough! The heat there was so intense it started bubbling and blistering the paint on the hood! That was all the information I needed to be confident in the purchase of this 2002 Buick Rendezvous!
After the purchase I cut the rubber seal down away from the hood at least one inch by two feet from center...NOTE! I was also careful not to remove the guard area for rain water. The lower section of the rubber guard takes care of that. For a test to be sure I sprayed water over the windshield and not a drop spilled onto the engine.....
Well it's been two years and not one over-heating problem since...... I have photos on the work done if you like......
