This is not an easy job. You have to take the a/c ducts out from under the dash etc. Get a manual at the parts store or DISCOUNTAUTOREPAIRMANUALS.COM

How do you change a block heater on a 1981 GM truck?

Locate the block heater. Drain out the coolant from the rad and from the block if there is a drain there. There should be a screw in the center of the block heater. Unscrew it to loosen the block heater internal clamp. Use a pair of pliers and wiggle it free. As long as it is not plugged in, there should be no worry of damage. It is sealed with an o-ring.The element will have to be worked out as it goes into the block along the side.

Why Mercedes heater blowing hot?

I had a W126 Benz (1981 280SE) on which the heater would not turn off on one side of the car (it has separate heaters for each side). The problem turned out to be a broken solenoid valve in the heater water supply. The way the heater works is: With the ignition off the heater valve springs open. When the ignition is turned on the heater valve automatically closes. When you then turn on the heater controls the valve opens again. I think the idea is that the heater valve gets "cycled" every time the car is used so that it doesn't get sticky. The electric solenoid that does the closing is easy to find by following the water pipes and will probably be on the firewall somewhere. They are supposed to be a throwaway part but I got mine open and soldered up the broken wire and all was good.
