Running B18c with out a thermostat

[locote]

It should be were the top radiator hose feeds the heads, i didnt have one before i took the part of and got it swaped at honbits..

That new thermostat opened alot later than honda one..
I put old thermostat back with type2 coolant and fan comes on at 92c so it doesnt idle over that...
Gonna go try to get my money back on that thermostat, its from repco so i dont see them giving me hassles

There is a bleed nipple/bolt on the p72 head, not on a pr3 though.

Abit of driving with the heater on and cap off/top a few times should more then take care of trapped air in the system.

Slaz,do U mean unscrewed but still on? If so wouldn't quite a bit of coolant come out?

is there a bleed valve on B-series? where?

not on the b16, but there is one on the b18
