so I have had over heating issues on a vehicle in general but never a car not fully warming up, what could be the cause? I drove the car 20 miles on the highway to no avail.
Background on the car:
bought 10k miles ago, immediately engine was rebuilt by me, water pump on the vehicle seems to have been replaced but I never touched the thermostat to know. I did 10 D & R after engine rebuild with distilled water and then poured in the 50% coolant that the vehicle requires and topped off with distilled water whenever it was needed, 10k miles no issues but today after 20 miles, the vehicle never reached operating temperature (the coolant I guess).
