Hello. Welcome to Just Answer. Please allow me to assist you.
You are correct in your thinking about the thermostat possibility.
If the thermostat is sticking closed, coolant will not flow thru the radiator and enter the engine. The fact that one hose is hot and the other is cold usually indicates a thermostat replacement is needed,
could it just be that the hose has a clog in it
I would doubt that.
There is also a used rad in it could this be an issue.
There is 15 pounds per square inch of pressure in the cooling system; a clog would not stand up to that pressure
A used rad, on the other hand, can cause this, if the internal cores are clogged
The thing to do would be let the engine cool off, remove the thermostat, reconnect the hose, fill it with water and run the motor
if the overheat condition continues, A radiator replacement might be on the horizon
I took it to my mechanic and it was pressure tested, so i know that there are no leaks in it. he was the one to drain, clean, and test it, as well as filling it. so my best bet would be to change the thermostat? can i do this myself, or would i be better to take it to a mechanic?
You best bet is the test listed above. I would recommend a mechanic so this is you do not have substantial expertise in this area.
I would recommend a mechanic for this if you do not have substantial expertise in this area.
Sorry about the typo
Darnit, I was hoping for a cheaper fix. I've been driving it in 2nd gear to keep the rpm higher. It seems that if its in the 2000-2500 range that it does not overheat. Does this also lead to the thermostat?
Thermostat replacements are not that expensive
Ok thank you very much.
You would do well to get it checked out soon
If the overheat condition is allowed to persist, you could damage the cylinder head gaskets(s)
That would be an expensive undertaking
Calling for quotes today. On average any ideas on the time it would take for this fix?
Depending on the car/engine, about an hour
what make, model and year is it?
I'm being quoted 3 1/2 hrs. 2002 buick rendezvous
3.4 L v6
3.5 hours is a very correct estimate. This particular model is rather involved.
The vehicle was not mentioned on my screen.
I really should have researched more before buying it. Looking at $600 bill to replace a $30 part. wow.
yes.....I am sorry to hear that. Those vehicles are rather labor intensive
4.2 hours to replace the radiator
well, thank you for the information. much more cost effective than taking it to a shop.
You are very welcome
