Based on the converstaions here,I drove over to Corona, CA (Aircraft Spruce) this afternoon and purchased the Micro 1000 CHT, a sensor and a 15 foot extension cable. It's all installed and looks great in my original center console.
So where is the danger point? Some posts say that hitting 400 degrees will cause a valve seat to fail. Others say they regularly see 375 to 400 degrees on their longer, higher speed drives. Where is the point that indicated engine heat danger? BTW: 74 2.0L all original FI w, standard exhaust. My thanks. Eric Read NOTE: Please note that this was originally posted in a CHT topic post.

your good! (IMG:style_emoticons/default/biggrin.gif)
Those temps fall well within the safe range.Jake say's 315 to 385 is normal operating temps. 400 is a high temp but I have seen 407 on my CHT gauge with no prob. I don't feel comfortable with those temps but they are rare. Mine runs consistantly in the 320 around town and 360 range on the highway at about 13.5 to 14:1 AFR with about 25* ignition advance @ 3k to 3100rpm ( hwy SPEEDS AT 70MPH) |
