We bought a 2002 Buick Rendezvous CXL a few years ago. We had a few problems with the heating and air shortly after we bought it. It was a car my mom bought but now she has a new car so i am the one driving it. The past few months we had to get a new thermostat put in, a new heater core, new radiator hoses, and now were out of ideas. A certified radiator shop said it was the heater core, but others didnt think so. Every time i go somewhere, i end up stranded on the side of the road. I am a 17 year old girl, who does not need to be sitting on the side of the road all the time. I will watch the temperature rise, then it over heats. And it doesnt stop overheating. One time it sounded like it was about to shut off. And it would not accelerate past 40mph. And i keep coolant in it, that is when its not leaking. We have been veri dissapointed it this vehicle. But we are trapped with it. If you have any suggestions, please help!

Replying to: michelle23 (Jun 30, 2008 6:19 pm) I would guess an engine mount or the cross brace bar(s) on top of the engine. I would also check the "shock absorber" which is mounted in the front of the engine. If you have had all that work done on the cooling system, someone might have taken one of those items off, and not reinstalled them correctly, or forgot to tighten them up. Don't know the history of the cooling system. Was the DexCool ever changed previously? Did it have the intake/exhaust manifold gasket leak(s)? Air might have entered the system at one time, and that just turns the DexCool to "mud". Not good on hoses, heater cores, thermostats, etc. Were chemicals ever added because of leaks? They can cause problems also. Has a good cleaning and flushing of the cooling system been done? Is the sepentine belt tensioner tight, making sure the belt is not slipping? Is the water pump, which runs off the belt, in good shape? With all the work previously and recently done, was the cooling system "burped" correctly? I know, alot of questions, but just some thoughts off the top of my head to see if anything helps you.

And also, it makes a clicking noise when u first drive it down the road Where is the clicking noise coming from. Does it speed up or slow down in relationship with the speed of the vehicle? Does it stop after a while? Does it stop when making a left or right turn, and than start again? More information please. Could be wheel bearings, brakes hanging up, bad half shaft axle bearings, etc. |

| A few more thoughts on the cooling system. Is the radiator cap working properly and is it the correct pressure rating? Does it seat correctly? Are both cooling fans working when they should? | |

I don't know if you've checked this but on my RDV the I have started leaking a small amount of coolant from the intake gasket. Mine won't empty the reservoir, but empty it to about the "hot" line. This is just enough to loose my heater during low speeds during the Minnesota or South Dakota winters. The clicking noise I have not encountered. It could be a belt of fan. Is the clicking audible in the car, or does it change with speed or RPM?

| ok lets start.... in the garage I start the car.... then shift into reverse then quickly shift into drive. or just shift from forward to reverse and visa-versa... I hear this "clunk" as an old timer I would say it sound like a bad U-joint. Have had a checked by two shops, one dealer. ]Both say not to worry... if sorta to be expected in a four wheel drive... IS THAT SO? The dealer had no shop notes on the situation... and the drive train shop said their puter said not to bother with it.... and would give no reason....... ANYONE HAD A LIKE PROBLEM, and what did you do about it? Please help.......................................Thanks..... | |
