Overheating on my uncles car
 

my uncle has a 289 bored to a 302 and it keeps getting really hot (64 and 1/2)

hes already bought a new aluminum radiator, replaced thermostat, drilled holes in it,

checked timing, had hydrocarbon test which was okay, installed electric pusher fan,

has mechanical six bladed flex fan, and has the right anti-freeze mixture

any ideas?

thanx

Has he had the system flushed the coolant passages could be blocked.

yep, it has good flow

it was checked by a mechanic

Did he get all of the air out of the radiator and motor?

he said he hasnt, but he wants to know how to do this

he had a 180 thermostat but it still overheated

changed it to a new 180 thermostat, took it to a mechanic

and the mechanic put a 160 thermostat in it and it still overheats

Take the radiator cap off (When the car is not hot!) and run the car for about 10 min. The air will perge itself out. Refill to top it off.

arite thanx, he's gonna try and see if it is actually hot

gonna take a temp gun to it to see if its not a faulty gauge..or faulty gauges

yep. just let it run with no cap and itll burp the air out. some people even jack the front end up so the air will raise to the highest point, being the radiator filler neck.

Also have him feel hte upper and lower hoses! When the car is hot both hoses will be hot if it is the Thermostat sticking closed the upper hose will be cold! and the lower will be hot
