Just been looking at the info on rads and overflow tanks .
What do you do with heater connections??

Thanks in anticipation , Phil

as in? connections/blocking off/?

Yes -do you just blank them off -

Well, I don't know whether I'm right or wrong, but I'm planning to connect the water pump secondary outlet (the one that used to connect to the heater) straight into the inlet manifold connection (which used to take the pipe from the heater.)

I remember someone telling me that this bypass connection is useful for something or other...

...mind you, I'd love someone to tell me that this connection is unnecessary, as it will save a piece of pipe flapping around and getting in the way of the plug leads.

Thanks David --now that I've looked at it after your info it makes sense

The cooling system requires that extra 'bit of hose' so that it can do exactly what it does, BYPASS the system. Theoretically you could do with out but it is better left on.
Consider.

You start your engine from cold, and the water pump starts turning & pumping water. This is only true if you have a bypass hose (normally routed through heater) because your thermostat should be closed (cold engine). Because you have no bypass there is static shock pulsing in the cooling system, ie the pump is trying to flow the water around the engine but it cant go anywhere because the outlet pipes are blocked (thermostat & bypass) so you then start getting a thermal shock heat build up around the cylinders and combustion chambers, the normal result of which is either a cracked head and/or a blown head gasket.
You could block the pipe and then remove the themostat, this would give you a slow warming up and result in similar problems because the thermostat shape forces the water to flow in a controlled manner around the cylinder block thus avioding hot spots.


Hope this answers your questions.


Enjoy.

I just knew there was a good reason why I did it that way...

Mine go to the Heater.

Thanks gents---one of the problems during the week is spending too much time thinking about the next job -without bothering to actually look at it and work things out -----------
Role on the weekend , for the next piece of mental torture
