Runs and drives great as long as iam moving even slow runs low temp. if I stop it will start to heat up never seems to boil over but orginal gauge will get high. Soon as I take off it will cool down. Things I have done and checked.
radiator has been cleaned out
took head off cleaned gunk out of water ports
new water pump
new hoses
50/50 water antifreeze mix
and stock fan is 1/2 in from rad
it will hold a piece of paper to rad
iam stumped still gets warm when idling for a bit any suggestions thanks

Try an infra-red thermometer to check the temps at various places on the cylinder head, water jacket, liquid in the radiator top tank, radiator outlet, etc. They're very inexpensive, particularly if you shop Ebay. I use mine frequently.

On an older engine that has been sitting that long, you may have a lot of rust and junk caked in the bottom of the water jackets in the block. Did you run a chemical flush through the whole system?
One other thing you can do is put a fan shroud on the radiator. I realize fan is only 1/2" away but, a shroud forces even more air through the radiator. | | | | | Joined: Mar 2016 Posts: 5 New Guy | | New Guy Joined: Mar 2016 Posts: 5 | ok thanks ya was thinking possibly gauge I will check with another gauge. my vacuum advance doesn't seem to work could that cause heating | | | | | Joined: Mar 2016 Posts: 5 New Guy | | New Guy Joined: Mar 2016 Posts: 5 | And yes took head off dug everthing out block is flowing good now
