Hello, Woody
How you ran non pressurized cooling system?
I think my srt6 has higher perssure than normal in coolant system.
It made damage on radiator and hoses.
I changed the spring of reservoir tank cap more soft to have very little pressure in reservoir tank.
But It resulted in lost of coolant.
At engine high temp., Coolant sprayed out along top straw of reservoir tank.(No leaks found at other)
I ran 178/69 stacked, SCAI, coolant Isolation, supercooler, speedriven S/C intercooler(no leak), bosch 550cc injector, sl55 fuel pump and eurocharged map.(new water pump & thermostat)
How can I run non pressurized cooling system like you without lost of coolant?
