hi chaps, right, ive had to undo 2 hoses that go to the thermostat housing to carry out a temp repair to one which had split. Ive wrapped it with some amalgamating tape for now.

I just want to know if its ok to just put the hoses back on and start it as normal or do i need to bleed the system or anything and if i do, erm, how?

cheers in advance chaps :D

It's a pressurised system so it's needs all coolant and no air in there. If you let coolant out, it needs to go back in. :D

so i should put the hoses back on, then start the car and release the bleed screw on top of the thermostat housing till just coolant is coming out right?

Don't start it untill its full, Oh and fill it slowly and don't forget your antifreeze!
