there is a thread about evans cooling systems. and yes, i did read all of it..

https://www.rx7club.com/showthread.p...=evans+coolant

however, my question is:

which one did u guys get?

NPG+

or

NPGR

or

NPG ( not recommend for daily car/ weather vehicles )


which one did u guys use? one of the forum member contacted with evans tech support.. they recommend to use our stander radiator cap ( 13psi ) but however, the NpG+ and NPGR.. have 7psi cap...

so..what did u guys use?

 

I'm curious what other people are run ing also. I found some evans locally but the store charges about $42 per gallon

 

After reading a bit more it seems that the NPG+ is the way to go unless you are running an electric water pump. I will beusing NPG+ I just hate to pay so much for it. And I can't find it on pineapple's site anymore either. Time to check ebay....

 

personally. .i will never buy those from ebay.
