I feel silly asking this question, but bear with me...
The radiator cap on my AUII XR6 looks original and fairly worn out. Went to buy a new one, but no one (Repco, SCA, Autobarn, eBay) stocks a 120kpa / 17 psi replacement, only 135kpa / 20psi.
With radiator hoses possibly approaching 17 years old, I'm a little hesitant using one with a higher pressure.
The only alternative I can see is the Tridon CN15100, which is 100kpa/15psi.
Any recommendations?
