Removal
Heater was optional. If you wish to remove the heater, how is it done?
- Drain engine coolant
- Remove heater hose from the fitting behind the cylinder head and plug this fitting
- Remove heater hose from the lower radiator hose tee. Plug this fitting
- Remove heater from inside car
You can either remove the fitting from the back of the head & put a plug in there, or get heater blank off rubbers & plug them both. You can get these from local Auto stores, it is 1/2" heater hose.
Heater hose plug for cylinder head:
cylinder head water connector:
Or the simpler way: Run a new longer hose from front to back of engine.
