Thermostat Question

I recently purchased a '49 F1 which is stock (V8) except it has been converted to 12 volt. After driving it locally a few times I was concerned as temp was running between 3/4 & H. I pulled the thermostats today and they were 195F and I am going to assume the stock ones were 180F.

I have already ordered the 160F thermostats as I was concerned about the higher temps. What temp thermostats are being used here? It will be warm weather driven only and stored during winter.

160's are stock, or close to it. Not sure switching will cure your problems but it sure won't hurt.

Shoot it with an infrared and see what your temps are, it might be your gauge since its been converted.

Good point, JB. How is voltage to the gauges being reduced?

I actually had to reduce it after I bought it as it fried the sending unit.

Thanks for the responses, I am going to flush the system with FleetGuard Restore + as I had to drain the system to repair a water pump. The thermostats aren't here yet so it will be a couple of days before it gets done.
