Water temp problem
- Thread starter jemccab
- Start date
I’m having the same problem. Engine is a fresh rebuild, rad was professionally flushed by a reputable shop, timing is bang on using a light (TDC, light just turns on when advanced 1 notch), temp gauge installed and new water pump and I was getting into the 210 degree mark. Flushed the block and rad making sure I didn’t leave rag or cap in either when I installed them. Couldn’t find any issues that would indicate why it would overheat so looked at timing and GAV. Plugs 1 and 4 were dark and saturated while 2 and 3 looked lean and hot.
The one thing I did find was my distributor rebuild kit I ordered has a smaller diameter for the housing. Used a dial indicator and mag base and measured 0.015” play axially so I was having a hard time maintaining the .025” rotor to distributor clearance. Put the old housing on and ran the car in the driveway for 20 min and never got above 150-160ish. Haven’t had a chance to put rubber to the road. Hopefully this weekend.

Jemccab, I post this comment for others that might read this educational thread. A digital imaging camera can be purchased or hopefully borrowed. It will show cool and hot spots in a radiator. Depending on quality, they are expensive. I have not seen one in action in person, but have seen pictures of their capability.
A digital thermometer, can be used to record temperatures left to right and down to create a view on paper. They are inexpensive to buy on Amazon.
Your temps are in line with our coupe. Without a thermostat, our coupe runs 75 -80 degrees over ambient. We drive all winter down to 25 degrees. I added the Vintage Precision thermostat.
I'm repeating what I learned in other threads. Hope this helps someone.
