monty1991 Posted August 25, 2013 Share Posted August 25, 2013 my car keeps filling the over flow bottle for the radiator. i'm using a cj performance civic rad and low temp thermostat.. i was told the rad cap wasn't good enough to hold the pressure thats why shes filling the bottle.. just wondering what cap you guys use? does a trd one fit a civic rad or do i needa get the likes of a mugen one? any help would be great guys? shes not over heating or anything.

Nanglebadger Posted August 26, 2013 Share Posted August 26, 2013 Hi Monty, I was using an HKS one on my civic rad and I found it created too much pressure and was filling the overflow bottle, so i resorted back to the standard one that comes with it and that fixed it straight away.

Nanglebadger Posted August 26, 2013 Share Posted August 26, 2013 standard 1.1 cap on mine dude. the HKS one was higher, maybe 1.4+ not sure. seems a bit odd that man. Phil. Quote Link to post Share on other sites

mikey4410 Posted August 27, 2013 Share Posted August 27, 2013 I didnt realise there was different cap pressures available,whats the need for a higher pressure one ? Why are there different pressures available ? Quote Link to post Share on other sites
