Thread: Rodding P38 radiator, possible?

This may explain why my RR boils the water out through the overflow - strangely though, the temp gauge doesn't move from the middle until the car has lost 2-3 litres.

Could be a blockage somehwere?

I have had a couple of scares, first time on a trip out bogged down in mud trying to get out suddenly the temp went up very fast. I was warned then of a possible rad blockage but that was the 1st time I had any issues with cooling so put it down to heavily stressing the engine but noted the warning. Viscous fan checked OK and no loss of coolant. Just before Christmas one of the heater hoses burst in a big way, I put that down to age and changed it along with a couple of the other small hoses. All seemed fine until last thurs in heavy traffic the guage went into the red very quickly and coolant overflowed from the header tank. Enough warnings, I left the car to cool off returning later to bring her home ( with no temp issues ) The top hose seemed rock hard though. The rad is out and was flow checked by the 1st workshop, its heavily blocked. Time for a clean out.
