Thread: No thermostat?.....

Tweet

There used to be washers with different size holes available to replace the thermostat. I've googled for them, but can't seem to come up with them. Maybe someone else on the board is more proficient at it than I am.

If nobody answers, use your micrometer to measure the thermostat thickness at the outer diameter where it is sorta crimped. Obtain some copper sheet of that thickness and cut out a washer to fit in the recess. Drill a 5/8 inch hole in the middle.

never heard of that tech. will have to remember that one. thanks

Thank you. Takes someone from the U.K. to show me parts in Kansas. Small world.

A water based system of 50/50 is a works on high pressure and restriction. If you take out a thermostat , you must plug the bypass. If you don't, the coolant will literally bypass the radiator and just circulate from the pump and block. When you block the bypass hose, all coolant now in the block must go through the radiator.
You can use the restrictor washers shown or even gut an old thermostat and see where that takes you. The downside to no thermostat is you will have very little heat for the heater in the car, if there is one. Upside is you can get the temps under control in hot weather.
