The 1st heating core Isolating Tap located on the right hand
side of the engine at the rear of the exhaust manifold.
Heating System
Coolant from the engine flows through the
heater core causing it to radiate heat into the
cabin when the engine is up to temperature.
The volume of the water travelling through
the system, and therefore the amount of heat
transferred, may be adjusted by setting the
temperature on the A/C head unit.
To enable the heating core to be isolated from
the engine two taps have been installed.
If the heating is not working when the engine is warm,
ensure that the isolating taps are allowing coolant to flow
through to the heater core.
