Good morning guys. Was hoping that you guys could help me diagnose my overheating issue.

History: My car was not running for some time (year or so). Car is now running.

What was done to my car to get it running:
New t-stat 160 degree
New upper and lower radiator hoses
Replaced radiator fluid
Rebuilt carb
Replaced head gaskets
Drained tranny & replaced fluid
Topped off rear end fluid
Bleed brake lines
New spark plugs

Car currently has
Electric fan
Shelby racing front apron

Yesterday I picked up my car from the shop. The mechanic said that he had driven my car around town and the car had no overheating issues. When I was driving home yesterday (stop and go traffic), the car was running from 180 - 190 degrees. About 30 min into the drive I noticed that the car shot up to 220 - 230 degrees. (I was averaging from 10 mph to 65 mph throughout the drive) I immediately pulled over. Once my car cooled down, I opened my radiator, and the radiator was still full. I did notice a tick in the valves. (mechanic said that the valves needed to loosen up, and then he would readjust the valves shortly).

Any ideas guys?

My thoughts would be:
Valves not adjusted properly causing the car to overheat
T-stat isn't working properly
Water pump isn't working properly (water pump was new, about a year old)
Aluminum radiator (may need to be flushed, radiator is about a year old)

Any help would be greatly appreciated.

 

What's your motor and fan set up?

 

289. Edelbrock intake, carb, mad ignition, edelbrock hi flow water pump. Rest of engine is stock.
Aluminum 4 cor radiator.
Believe the electric fan pulls 2075 cfm

 

Is the issue when you are sitting still? Cruisin at like 3 thousand rpms or just all of the time?

 

When cruising at 2500 rpm (65mph) I was ranging from 180 - 195 or so. Lower speeds 30mph and below was when the car temp shot up and I had to pull over.
You can hear the electric fan running. Didn't loose any radiator fluid. Car was pushing 220 - 230 though.

 

I was in stop and go traffic. But cruising thru town not hitting lights I thought the car should be running lower temps than 180 - 200(max)

 

can you post a pic of you fan setup?

 

What kind of aluminum radiator is it? Is it a quality piece or a Chi-Com special?

 

Yeah sounds like to me it's a fan issue not a coolant flow issue

 

The radiator is a champion. It was like a $250/300 chepo radiator. Always kept the car cool previously.
The electric fan kept the car cool previously. Would you suggest I switch to a mechanical fan (flex-lite and a fan shroud)
