I run my AC for at least an hour a day not continuous but usually 20 minutes at a time. I took a temperature reading off the heads with my temperature laser pointer reader thing and it shows their running 300 degrees. Is this normal operating temperature?

I'm not sure what the normal temps are tho & no way to check mine, sorry. I have a small fan on mine cause its kinda in a corner. | | | | | Joined: Aug 2005 Posts: 6,377 Ex Hall Monitor | | Ex Hall Monitor Joined: Aug 2005 Posts: 6,377 | Ditto 64Fleetside, I don't know the exact operating temp but the heads will get pretty hot when operating. If you look closly, the pully that turns the crank connected to the pistons is shaped like a fan to help push air across the cylinders to aid in cooling.
