Re: 3.5 RR classic cooling issue

Re: 3.5 RR classic cooling issue

Thanks Frank, thats really informative. So, in summary, you would suggest sticking to the way I have it plumbed now (bottom radiator hose plumbed into the base of the tank, with the inlet manifold small hose to the radiator and the other small hose to the tank).

Re: 3.5 RR classic cooling issue

Thanks for the reply Ian, much appreciated. Yes, the pressure cap is on the tank. To clarify my understanding, the two small hoses that go from the radiator and manifold to the tank should be restricted ? But the hose that goes from the tank to the bottom radiator hose shouldn't be ? Whats the best ...

Immediatly after installing the gauge I started getting strange readings, it would tick over for 5 mins and...
