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!!

SOURCE: 03 Buick Rendezvous Overheating

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.

SOURCE: buick rendezvous overheating

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......

Head gasket or IM gasket? overheating, think there's antifreeze on spark plug threads. drained flushed bled system. new thermostat rad cap. still overheating.


Somebody been using tap water in their radiator? The vehicle is old enough to have a lot of accumulated rust and crud in the Radiator which, depending on relative water quality and location of water pump could over pressure the system and have it squirting into overflow. If the threads of the plug have antifreeze on them it's coming from the OUTSIDE not the inside.

Radiator boiling into recovery and boiing out


Does the vehicle overheat on the road? If it does and pushes big burps of coolant into the reserve tank then you could have a head gasket leak. Usually what happens with a head gasket leak is that the engine will often start and run normally but will soon start to push coolant out in a kind of foamy burp as the combustion gasses that accumulate in the engine block force their way out. You can have a small head gasket leak that allows combustion gasses to escape into the cooling system without getting coolant back into the engine and often the first symptoms of this kind of a leak is a motor that suddenly overheats, the heater quits blowing hot air and after a short while everything returns to normal for a day or so. As the leak worsens however it may keep pushing coolant out of the reserve tank with a cool or cold engine as the pressure builds to quickly for the reserve tank to handle it fully. Having said that if you have a perfectly good cooling system that is hot and take off the radiator cap it will spray blistering coolant coolant all over so never remove the cap from a warm or hot cooling system! Most additives won't stop a head gasket leak as there is just too much pressure for them to "stick" in the leak and they just get forced out of source of the leak. It's rare but you could have a water pump that's not circulating enough coolant around but usually you have different symptoms than this.

OVERHEATS AFTER THERMOSTAT REMOVED


take fan belt off so water pump does not turn. take thermostat housing off. make sure water level is close to top of thermostat housing (inside) start it, look for air bubbles... If you get them it is due to leaking headgasket, this will be the cause of your overheating and I suspect it's pushing water out too... Just a guess with the limited details.

Leaking antifreeze


A quick check you can do to help your troubleshooting is to remove the radiator cap then start the vehicle. (Ensure radiator filled so you can see fluid level). Watch the fluid inside the radiator. Initially after you start the vehicle you will get some small air bubbles but they should go away in less then a minute. If after a couple minutes you have bubbles continually coming up or it starts bubbling out of radiator then you can bet on the Head gasket. If you do not get the bubbles it dosen't rule out either one but if they are there as described then you can look at the head gasket.

98 crv still overheating


I hate to be the one who tells you but,if your radiator cores arent blocked as you said you have your radiator fixxed,its a head gasket,antifreeze is leaking by the head gasket and going into the piston chamber when the piston goes up it pushes the fluid back into the radiator,check your oil distick for a milky white look,antifreeze in the oil,if your car starts to have white smoke its antifreeze getting into the exaust ports either way head gasket
