Swampy442 Posted October 13, 2015 Share Posted October 13, 2015 Also a 1.3bar cap is way too strong, a standard 0.9bar is fine Quote Link to comment Share on other sites More sharing options...
Nic Posted October 13, 2015 Share Posted October 13, 2015 Also a 1.3bar cap is way too strong, a standard 0.9bar is fine over pressurising the system is a common cause of the heater matrix letting go, which is a complete dash out job to replace.

mattdavies Posted October 14, 2015 Share Posted October 14, 2015 I thought 1.1 Bar was the Standard rad cap ? Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted October 14, 2015 Share Posted October 14, 2015 0.9 is the standard rad cap, 1.1 is an 'upgrade' Which it isn't. Quote Link to comment Share on other sites More sharing options...

Swampy442 Posted October 14, 2015 Share Posted October 14, 2015 so I should use a standard rad cap Yep, you gain absolutely nothing using a higher pressure cap, except putting extra pressure on your cooling system Quote Link to comment Share on other sites More sharing options...
