Hi guys

I am just starting to buy the parts to finish the cooling system on my GTM, it has a front rad and I was just wondering if anybody had any opinions on running the hoses.

Should I send the hot water coming from the pump to the top of the rad or the bottom? I know that it goes to the bottom on a mini but I have seen differing opinions on this, as I have the option to do either, was wondering what is best? My first instinct was to run the hot to the top...

What do you think?

Hot water to top of the radiator, as per the majority of all cars including minis.

ok how does the pump work?

 

standard sucks out of the bottom of the rad and pushes it through the engine to the top of the rad.

 

I would fit an expansion tank to the bottom hose and have a small bleed to the ET from the thermostat housing.
