Re: LS swap coolant temps
All of you are running a lot cooler than me. I’m using a Holley frostbite radiator with F-body fans. In the summer without the A/C my 5.3 runs between 208-210 and with the A/C on it runs between 218-220. It drives me nuts. I’m about to add an expansion tank as I lose some fluid through the vent. I keep reading these are normal temps for the LS, but I DO NOT like running that warm.
