| 295 Cooling hoses for the RV8 Mike Howlett posted a query on the V8BB seeking help with the cooling pipes on his conversion. (Feb 09) Mike Howlett said "my conversion, which is nearing completion, uses a 1991 3.9 litre Range Rover engine and so is very similar to an RV8 in layout. The water pump has only one outlet on the rear and the normal flow is from the inlet manifold, through the heater and back again to the back of the pump. I have a couple of questions with respect to the engine cooling circuit. Firstly the steam vent, you know, the little pipe that pokes up out of the inlet manifold - where is connected to on the RV8? Can I "T" this pipe into the pipe to the expansion tank? Secondly, the RV8 uses an in-line water valve for the heater, and I intend to do the same. However, if I do that, I will block the coolant flow as described above whenever the valve is closed. This doesn't happen on the Range Rover because it uses a permanently hot, air-blending heater. What happens on the RV8? I am currently thinking of simply fitting a joiner between the two heater pipes on the engine side of the heater valve. Will this work? I hope someone can enlighten me. I unfortunately don't know anyone who owns an RV8 to ask!" |
