Engine Temps

[DonHo32]

I am running a 160 degree Tstat and electric fans, but i notice at times the temps rise to 210. Will this have a major effect on spark knock? And at what temp would this begin to effect knock? Thanks

Yup, get a "real" temp guage then make SURE that the system is free of any air. Air in the system will give you temp spikes!
My system: With engine completly cold check radiator and top off. Start and warm engine untill t-stat opens, you'll see the water moving. Top off again as much as necessary while engine continues to warm up. Install rad cap making sure line to header tank is clear and tank is 1/2 full or so. Let engine cool completly one more time (overnight is best). Check rad (not header tank) one more time, top off if necessary. Little time consuming, but it works.
