Reply to "Filling a completely dry coolant system"

quote:
The other thing that you MUST do in a Pantera is the water pump that you put in MUST have the fast warm up bleed hole in it.

The Wieand pump does not and it must be added.

Without that bypass hole the Pantera WILL overheat and you won't find the cause.

For some reason the bypass hole is not drilled by Wieand. They know that, and they call it a fast warm up modification. It plays havoc with the 351c's cooling system.

Doug - I'd love more info about why the water pump bypass is necessary. I've had a Weiand water pump on my Pantera for about 10 years and never had it over heat. The Weiand pump does allow you to run a 351W thermostat, although I still have the correct 351C thermostat in my car.

Thanks!
Garth
