Title: It's all about the temperature!
Post by: Larryowen on April 15, 2022, 11:02:22 AM

New 350 Chevy engine with about 400 HP. Running terrific but water temps seem to be too hot. Gauge reading 190º at, say, 3500 rpms. However with my hand-held LED thermometer I get readings of 125º-145º taken from the thermostat housing, the hoses, the manifold, the engine block and the risers. The new crank-driven water pump is flowing a LOT of water. Also has new circulating pump system. Can a new gauge and sender be that far off ... what am I missing?

Good question. I did use  2 different hand held units with very close to the same readings.
