Heater control question

Post by 1970 cortina GT »

Quick question on my heater control on my twin cam. I would have thought that I should be able to set the open and closed positions on this unit but it ‘springs’ back to the same place when I let go of the small tab in the slot? Consequently it is too stiff to operate on the heater inside the car. Should this be like this or should I be able to set it anywhere along that slot to adjust temperature? Thanks.Image

I wonder if that stiffness might indicate the valve is beyond it's best by date and maybe it will leak when put into service??? There are a few rubber bits in that valve that can perish over time.

My own car does not have any heater valve at all and it has never bothered me, I just don't turn it on when it is hot outside. Perhaps a simple elbow might work?

These are pics I found on the net.

There are a selection of replacement heater valves available on ebay

Thanks gentlemen, a good alternative Brett, also a good lead Pete, the Lotus one I found was over $360 in Oz.... why is it people get carried away when you put Lotus in the search.... I figured it must’ve been used in other cars.ðŸ‘￾

Just a follow up here on the heater control. The Triumph one you gave me the lead on Pete turned up, will work good I think. The only issue is that it will be in the closed position when the indicator inside the car shows hot and vice versa. Not a big deal, I have got a local place to make me up a new inlay for the heater with the hot and cold switched.

Could you just switch the polarity of the wires to fix the gauge issue?

I’m referring to the ‘slide’ lever on the heater unit in the car. No electricals involved. But thanks.
