[MR2] mk1 underheating

[Bob Schultz]

Steve can back me up on this... it gets really cold in Michigan

The only Mk1 Mr2 that didn't make great heat had a plugged heater core.

I agree with your logic, yet find that hard to believe. IIRC, the heater 
hoses are in the "inside loop", inside of the thermostat. If you have a 
cold car, and a closed thermostat, and the engine is heated-up and at 
operating temps, that's scary-cold ambient weather!
