Ahh true, good point, hadnt thought about the size of the pipes. Cheers.

Would it make a difference that I have removed the part that controls the hot/cold of the heater unit? I mean the old vacum box that would send the hot water from the engine into the heater core when you turned the dial to hot. I was just thinking of running the heater unit on hot all the time lol.

Cool cool, guess I cant get rungi on it and will have to do it the proper way hahah

Thanx heaps
Matt
