Running Cold
Temperature gauge in cold zone. Heater putting out warm air, not really hot as usually. Last night checked top hose was only warm. radiator cap was cold. Cracked cap, it had pressure and water. Ambient temperature was 50deg. Drove 25 miles engine appeared to be running normal.
Flushed and installed new thermostat 3mo ago.
Will have to investigate today after coffee.
Any ideas?
