Re: pinto heater

why not put a stop/closure valve in the heater feed pipe?

Thats a useful get you home fix if the heater matrix ever leaks. However as Tony says, why not fit a simple stop valve? Try Car Builder Solutions as a first port of call. Peter.

Re: pinto heater

Be careful that you retain the use of the full volume of water otherwise you may have an overheating problem

Re: pinto heater

Thanks Dave don't think I can do that I would lose the water volume in the heater as you said, but will try later heater may be ok now weather has changed, thanks to all.

That should not make any difference - it's all about the flow rate and the cooling in the radiator - losing the extra cooling that you get from the heater may be important if you are marginal but the volume of water only effects the warm-up rate

Re: pinto heater

You need two valves, one to cut off the flow to the heater and one to maintain the flow that would have gone through the heater to maintain the coolant circulation during warm up till the thermostat opens. The amount of water in the heater is negligible, but the flow path is important.

Re: pinto heater

My preferred solution is to use a “ford fiesta heater valve”. This valve used on several cars (Fiesta Ka Transit Mazda) it is combined with a temperature control from one of those vehicles to vary the heat. The unit is fitted to the heater flow and return pipes. It allows water to flow to the heater or diverts the back to the engine. The valve is an on/off device either allowing full flow or return. If the control is set to a mid position the unit switches position regularly.

Although it is a bit more work it is a great deal better than having to stop the car and lift the bonnet if the evening cools down.

The ford valves are readily available and relatively cheap. I daresay other valves are available and some cars monitor the cockpit temperature and adjust the flow to maintain the comfort level.

My car is a Cabrio I know some owners will consider this suggestion out of line with the rudimentary simplicity of the Roadster. I’ll be donning a flameproof suit immediately.

I remember working on a Volvo Estate, that had a non-electric version of this that closed off the heater matrix by virtue of an in-cab sensor, a slider controlled the degree of heat allowed into the passenger compartment.

Re: pinto heater

Keeping it simple, I suppose the electric valve could be controlled by just a switch, so being either fully open or fully shut, but it wouldn't be a whistle and bells job!

Re: pinto heater

Or you could use one of these which is what I have on a T7 heater matrix.

Include a picture of the heater it might help us diagnose why it will not turn off.
