If I am not fitting a heater just now can I just blank off the pipes for now, or what is best to do with them as obviously water comes out it, thanks

Not allowing me to post the picture, will try again

Just black them off.

Or connect a hose between them. The water will just loop round.
Should you ever wish to fit a heater it will be easy to fit the inlet & outlet pipes.

Hi,

I always fit a hose between the heater inlet and outlet unions on the engine, so that the hot water keeps flowing ... which is the latest way of doing things. The heater output is controlled by the amount/mix of air passing through the "always hot" heat exchanger.

Way back when, Reliant Scimitar GTEs (using Ford V6 engines) were renowned for warping their engines, while Granadas did not have a problem.

Years (many) ago, I read some research into this.

My understanding is that the Granada heater was always hot, and cabin temperature was controlled by a mix of ambient air, and freshly heated air. There was no restriction preventing ALL the hot water going back to the main radiator.

But on the same engine, fitted to the Scimitar, the heater temperature tap could prevent hot water in the cylinder heads from circulating, other than through the heater radiator.

On my Scimitar GTE, it was a race between getting water into the radiator faster than it poured out of the exhaust pipe.

That car pulled 30mph per 1000RPM in "30% overdrive top", and red-lined at 6500RPM. I found an indicated 130MPH (plus a smidgen) was on the limit of my comfort zone .... other cars were reversing towards me in an uncomfortable fashion ... and anyway, I was running on SR tyres. Strangely, it returned 30mpg+, cruising round Devon and Cornwall, in overdrive top, pulling a 12ft caravan.

Once upon a time, the Ford V6 engines were a desirable conversion for Series Land Rovers. More power, and more MPG. Kits were available from Steve Parker ... IIRC. It was reputed that any RWD Ford gearbox would fit onto any RWD Ford engine, but Steve Parker denied that a Cortina engine would fit his "V6 into Series LR" conversion kit.
