cooling system pressurising problem

[Johnny-C]

right ive a problem with my coolimg system pressurising.the pipes feel like they are about to go hard,and the whole system heats up very quickly.

i think its a problem with my golpher alloy rad,ive spoke to corey on the matter as he had a similer problem and it turned out the rad cap wasnt letting the system breath due to the rad holding the cap down to tight(not letting the coolant passed it).

ive file;d the rad slighty to not hold the cap as tight,but doesnt seem to be much help.

ive tested the thermostat,its fine.

water pump is new.

rad cap is a blitz item.

anyone else had a similer problem with a golpher rad?

its doing my head in at this stage.

Pressure in the system could be signs of head gasket gone, on my BMW when I opened the rad cap it would literally explode out of it

[Johnny-C]

It's a brand new gasket,head skimmed etc,so doubt it.

Change the rad cap

Was the head pressure tested?

[Johnny-C]

Yeah head is 100%. It's pointing towards the water pump ATM.

Does it overheat?

J to the C...i dunno if this is helpful, but when i fitted the civic radiator i also fitted a blitz radiator cap. i then had over-pressurisation problems and she was spitting coolant out from somewhere.

so, i changed it back to the stock cap that comes with the civic rads and haven't had a problem since.

maybe worth a try.
