heater hoses

Post by **sidsmith** » Thu Apr 24, 2008 1:52 pm

can someone tell me what the valve is at the rear of the engine that links the heater hose. I want to block off the heater as I only use the car in the summer, and it gets rather warm inside the car even with the heater off.
should I turn the valve off or could I disconnect the two hoses from the engine ( heater in and out I think )and join the outlet and inlet on the engine with a hose to complete the water circulation. your input would be well recieved.

just close the valve to stop the internal heater. Thats the purpose of it ;-)

But it's still handy for de-misting on wet muggy days - usually closing the flap is enough to keep the heat in without closing the valve. And in hot weather - it's better to have the water going round the back of the engine - so - if you do want to disconnect the heater then yes - add a little bypass pipe to keep the water moving. You must have prior knowledge that we are going to have a nice warm summer!

It depends on the type of valve, from your wording I assume its the gate valve type with the wheel on the top, if its the later type its controlled from a push - pull control just under the drivers side glovebox area.

Speaking of which.
I have the same "problem" .
If I close the valve ,gate valve type, than the heater still gets warm.I presume the valve is not really closing.In my shed I also have the newer type valve with the "remote"control but if I close that valve I am still able to blow some air through,if I put it on my mouth that is ofcourse.
Is that done on purpose to keep some circulation i.e. better cooling near cil. four?
Or is this valve also at fault ,what would be pitty ofcourse.
I don't have the problem in my saloon but in the traveller is a mini heater installed and he gives off much more heat.
I intend to go to the national rally and because you always have those beautiful sunny summers it's better to turn the heater off

You'll probably find the rubber stopper inside isn't moving quite as much as it should, allowing a small amount of water (air when blowing!) through.

When messing with the pickup I went through over half a dozen used ones that were kicking about before I found one that worked with any level of valviness at all.

Then I guess I will have to find out which one is best.
Afterall it's not that important but my wife is of that certain age that she suffers from heat and cold every now and than and the best is than to keep it cool

I always run with the heater oh. If you lose water, then the heater goes cold. Cheaper than a temp gauge.

But,but I already have a temperature gauge installed.

In my case it could help me to see if the temp gauge is functionning.

Fortunately - the Minor comes with 'climate control' system - the little quarter lights open and swivel overcentre to direct a cooling rush of air (and rain - and flies) directly on the face if required!
