Re: Wtb Dewitt's radiator and spal fans
My OEM radiator plastic tank separated from the core, so I used that as an excuse to get a Ron Davis radiator.
(I consider the RD rad in the same category as a DeWitt's.) To cool better, it is thicker than stock so I had to trim
the fan shroud. BFD. Car runs cooler in general.
Assuming the basics: radiator is clean and not blocked, coolant is correct (water wetter?), thermostat works, etc.
there are some other options to run cooler:
-Have you tried cooler spark plugs? Consider them your summer plugs.
-A high rise hood. Not only more room for air flow, but more air can suck in from in front of the windshield.
Not to mention how COOL it looks!
-Down shift. Counter intuitive, but it works. You can thank the Z's cooling system design.
Obviously in stop and go traffic this is useless.
-manual fan switches
I've never understood how a 160deg thermostat will make the system run cooler than a 180deg stat.
Yes, it will open sooner, but eventually the system temperature will rise to it's open thermostat "equilibrium" temperature
(greater than 160) regardless, right?
