Temperature Control Knob
« on: February 14, 2021, 12:54:38 PM »
I have a question about my 1975 MGB. The temperature control knob is very hard to turn. Looks like it has a new cable. Hard to turn it completely off. It had engine work done before I bought it.

Disconnect the cable from the heater valve under the hood and the see if the valve moves freely. Also see if the temp knob now turns easily. Often the hot water valve gets stiff if not used.
