Heater Bypass Help

[onedroppr]

Hi everyone,

I'm in the process of bypassing the heater. I'm at PR and I don't need it never.

Can I put a hose directly from the steel tube above the exhaust to the water intake in the back side of the head?

I plugged the steel tube once, but pressure keeps rising and melted the plastic cap.

Any help is welcome!!

The problem with a hose is it could easily chafe back there and leak and the reason the plug you put on the steel tube failed is because you used plastic. There is no pressure in that tube to cause the cap to fail, the steel tube is a return line to the water pump. To do it right...

Buy or make one of these and block of the water passage to the heater control valve at the back of the head. Then remove the steel pipe and fit a rubber bung on the water pump where it used to lead to. Make sure you use a rubber bung made for coolant systems, normally available at any auto parts store. GL

If there's no pressure on the steel tube, why it had lost a lot of water via that way when the plastic cap broke?

There's another problem on the system causing pressure going that way? Too much water on the system?

When I bought the car, a plastic cap was used on the outlet of the heater valve. That one broke when I changed the reference sensors. The I decided to plug it at the steel tube.

By the way are you telling then, it's possible that the head is already blocked. I'll see this afternoon.

Thanks

Water flows from the back of the cylinder head through the heater valve and heater back through that steel pipe to the water pump. So if you block off the water pump with a rubber bung the pump isn't pumping water to the bung, its going the other way.

Then you need to fit that metal blanking plate at the cylinder head to stop water feeding the heater circuit.
