| Hello everyone,
I am new to the forward look cars and this is my first of many post.
Can I plug off the heater at the block or should I plumb some fittings to make a bypass?
I recently got a 1959 dodge coronet lancer. Everything thing seem original and works great. Buuutt…. I live in Texas and I know I will not use the heater. I actually feel the heat in the car when I drive the car. I wouldn’t want to feel the heat In The middle of summer either. |

| Thank you, I will order the valve but do I need to add a manual valve to both supply and return side? Also This won’t create weird cooling issues down the line by blocking the heater? |

Location: So. Cal | No, you only need to block one side to prevent the flow. It's best to block in inlet to the heater to reduce the pressure in it though. It won't cause any problems. The stock system uses a valve too, and is supposed to block the flow when you turn off the heater. If the seal on the stock valve leaks internally, you can get heat even when you don't want it.

If the heat shedding capacity of the heater core is what's keeping your engine from cooking you have bigger problems . . .
If you will NEVER use the heat in the car it is perfectly acceptable to block off both the feed and return fittings at the engine - there will be no ill effect on the cooling system operation. Can't remember the last time I saw heater hoses, valves, or fittings on a competition vehicle. Which puts much more stress on the cooling system.

Location: North Germany | It's just my personal opinion: you write that your car is completely original - a modern plumbing valve really doesn't look nice. Personally, I would repair the original valve so that it closes tightly. But in your case, I would at least look for an invisible solution. You can disconnect the hose and insert a 2” long piece of plastic or similar into the hose to interrupt the water flow. Once the hose is connected, you won't be able to see it. It's certainly prettier than a plumbing valve.

plugging or bypassing the heater
