i'l try your advise and see what happens. ive no heater conected yet. ive got a new heater and wied up the fan, i just need to plume it into the engine. may be i should get that done before i pop the rad back on. ive just instaled a 3rd fan on the other side of the rad to try and help keep it cool. as is the course i find with custom cars its try try and try again till it works lol.
