Over heating

Post by Sam_Mendenhall » Mon Aug 26, 2019 12:15 pm

I ran my speedster with a 23 radiator for many miles without any heating problems. I recently changed the front end and radiator to a
14 brass, which was suppose to be new. After about 6 miles it started to get hot and boil. I have not changed any timing or anything else that would be related to heat problems. Any suggestions as to the problem would be welcome.

Did YOU purchase the radiator new or was it purchased as a "new" one by you ? Flat tube or round ? Perhaps it was sold because it didn't cool ?

Good catch Steve!

I ran into this once, drove me nuts. The baffle was place to low and starved the condensing process!

Just saying.

Antifreeze

Post by Novice » Mon Aug 26, 2019 2:57 pm

Did You use antifreeze in the old radiator. I read that antifreeze will raise the boiling point well above 212 degrees and if Your not using it in the new one could make a difference But one would think the new brass radiator would be able to dissipate as much heat as a stock T engine produces. If Your engine is souped up it could perhaps produce more heat. also any fan or radiator spacing changes could affect it. could also be a flow restriction of some sort that doesn't show up until You have been running hard for a while.
Good Luck
Jim
My 2 cents worth maybe less

A friend of mine bought a new radiator for his '26, installed it and it overheated almost immediately. Turned out there was a plug in the water outlet that he failed to notice. It had quite the detrimental effect on coolant circulation!

Sure sounds like the "new" radiator is the root cause. As long as you don't have a leaking head gasket...
