Escort heater connections
Here in the midwest USA it gets very cold. -15C and I need a heater.Where on my British made locost engine are the connections for heater hoses? It
has a 1979 Escort mk2 1300cc 711m block. There appears to be a hose from the water pump to the stock intake manifold (I assume for carb preheat).
There is a small plugged connection on top of the thermostat housing. And a pluged hole in the lower left hand side of the block. I have looked all
through my Haynes manual and NOTHING. I need help. My fingers are turnning numb, Russ

The heater send is connected from the inlet manifold to the heater matrix, then the return is from the matrix to the connection on the water pump.
DO NOT PUT ON KNOB OR BOLLOCKS!

The ONLY water hose on the engine is the one that goes from the water pump to the intake manifold. How does water get from the manifold to the
block???? Is there a passage internal??? Tks Russ

ok, from meory it goes like this. the water pump impeller (the thing on the end of the rotating thing iinside the water pump) is pushing water into
the block. the water is pushed upwards into the head and come out via the thermostat housing. thisw goes into the top of the raidort, coming out of
the radiator via a hose (the one you refer to) into the water pump and so forth.
now the bit I';m not 100% sure about is there is another small tube off the water pump that is for the heater, this goes to the carb manifold on
yours (& mine) but make a break in there and you can fit your heater matrix.
if I am wrong, then someone will correct ^^^^.

Yes - it's fairly straightforward. The main water circulation is water pump - block - thermostat housing - radiator - water pump (when the
thermostat is open).
There is a secondary circuit from the water pump to the inlet manifold, as you have seen. This is normally the heater feed, one hose from the pump to
the heater, and the return goes to the inlet manifold.
If you don't have a heater then there should be a hose directly between the pump and the inlet manifold, to provide circulation while the
thermostat is closed.
Does that help?
cheers,
David

Yes there is an internal passage. Split the line between the manifold and pump for the heater.
