Standard Rad Cap Pressure?

[kwazza11]

Hey guys.

what cap pressure do r32's run? the one on it at the moment is 90kpa.

that is all

goto repco and buy a 560-90, it is the same one. You can buy all sorts of other ones like HKS and Nismo but it's simply not worth it. the 560-90 will set you back around $12

Don't think about runninh a higher pressure cap UNLESS you replace every single hose and hose clamp.

Higher pressure rad caps will blow hoses much more often.

yea was just checking that i hadn't been running a lower pressure cap. but i think the problem lies elsewhere. clutch fan comes off tonight and 16" thermo goes on with standard shroud. hopefully that'll stop it boiling and pushing all the coolant into the res when i start giving it stick..

Oh and its only done 60km's since every hose and clamp WAS replaced.

about enough to get to the dyno then lobethal and back!

Checked water pump, maybe thats leaking/seeping a little not allowing pressure to build up resulting in a lower boiling point.

Have a feel under the water pumps snout for a little hole if its genuine or on top of the snout if its aftermarket.

Also check afr's and ignition timing.

I drove to Lobethal last night.

Best approach is also to pull the radiator out, take it to a radiator place. They will take the head off, flush all the shit out.

I used to have this heating issue too, changed my thermal stat, changed coolant 3,4 times..ect and at the end its just the bloody radiator that was block.

Water pump is brand new as is the radiator, and no coolant leaks that i can see. will pressure test the system tomorrow after i rebleed the system, has a modded plenum on it which has no bleed screw so should be a right bitch to bleed all the air out of it again...

afr's are rich when on full load, in the low 11's and perfect on cruise but haven't checked timing, could be a factor with the bodged jap tune of my fcon v pro. only really cooks when i start boosting it for longer than a couple squirts so could be on to something.
