coolant plumbing tip please
Hi all,
I am going to block off the heater outlet from my thermostat (heaters are for wimps right?!?!?!). Am I right to think that I can fit a stubby bit of
hose to the thermostat outlet and then block off the open end with an appropriate size bolt and jubilee clip?
Thanks
Chris

Yep or you can make or buy a nice bung. An alloy one weights bugger all and will have grooves to stop it blowing of.

Don't its part of the cooling called the by-pass water circulates in it even when the heater is off.
If you block off the by-pass the thermostat won't open until the coolant in the top end of engine is on the verge of boiling while the
bottoms of the cylinders will be over cool.
Older tin-top engines (roughly pre-1965) such as the BMC A & B series had water valve heaters and had the by-pass built into the engine between
the water pump inlet and head this kept the water flow circulating even when the thermostat was closed and heater turned off.
More modern cars have air blending heaters that is the heater core has water flow through them even when the heater is off the heater temperature is
controlled by blending hot and cold air flow.
To remove the heater all you need to do is link heater hoses, you can restrict the flow a little but leave at least 12 mm bore to allow enough
flow.
