I had what I thought was a tempature problem of running hot with my 69 camaro. I had a 2 row radiator that cooled a 307 until I changed to a 3 row which cools a 350 bored 30 from a 76 corvette, I also changed the termostat to a 165 form a 195. at idle it is running around 150. Could this cause any problems by running so cool or will it just make to engine last longer?

Welcome to the club!

This sceneriao has been around the block a couple of times. It appears 180 is a good temp, burns off condensation in the oil and makes for a hotter combustion charge than 160*. If you have A/C, you might consider 195 stat and a 22 lb cap.

You should at a minumnum install a 180* thermostat and make sure the radiator cap and hoses are good. Might even add a coolant recovery system.

How abouty this one. My car has a 180 thermostat in it. In cold weather it has been running hotter than in the summer. I am guessing the cold weather is blowing on the motor enough to keep it from reaching the the 180 at the t-stat. Weather warms up and it runs at a cooler temp. Wouldnt have guessed it.

73/74 mix. (Its a mutt) 73 350 bored 30 over, Th350 tranny. With the Lord willing, may we never have to drive a MiniVan!

how about humidity, the water in the air might transfer more heat even though the temp differance is smaller

just a thought

An operating temperature of 150 degrees is too cool. Where do you have the sender for your gauge mounted? Are you sure that the gauge is accurate? An infra red gun (pyrometer) is an excellent tool for accurately measuring the operating temperature of you engine. If you are running a 195 degree thermostat, your engine should be running at 195 degrees at a minimum unless coolant is somehow bypassing the thermostat.


I had a similar problem on my car. I made a cowl induction air cleaner for my car last summer. In the winter time, my engine was seeing 30 degree air rather than 80 degree air and the mixture was leaned out enough to make the engine run a little hotter. Going up two jet sizes alleviated the problem. You might try going up a jet size or maybe two on the primary side. That might fix your problem.
