Check the thermostat as well and then point and shoot to verify the gauge is correct.

Stay cool.

Thumbs up 454 Tends to Overheat

Thanks Glenn. I am always suspect of dash gauges anyway. I will know more when we head South with the toad for a 300 mile round trip to Abilene as a test run. Later we plan to go North to Denver which will include pulling Raton Pass with car in tow. If the Silver Hornet will overheat, it will be up the long pull up Raton Pass. Our diesel pusher would have a temp rise of 20 degrees up the pass. I am hoping we can have less on this unit. Our other gasoline m/hs have not been a problem on Raton, but the Silver Hornet may be different.
Mike

Glenn, after much freeway driving and stop and go in traffic I am happy to report temp got up to 215 degrees without using auxilary fans. Of course it was'nt 100 degrees out today either. Temp stayed at 215 and varied some when the fan clutch would kick in, but that seemed to be where thermostat and fan kept it.

My first drive ever in a moho was from San Jose to Black Rock City, Nevada, which took me up highway 80 into the Sierras, past Lake Tahoe and Reno. I was in a 30' Fleetwood with a 454, and I learned a lot about driving it uphill. If I didn't keep my speed up on grades it would drop a gear and never recover it until it got fairly level. It would run cool and smooth at 60 to 65mph uphill as long as I didn't let up on the pedal, though. In Gerlach, Nevada it was 107 degrees, and as I slowed from 65 to 25 to go through town(lined with police and rangers) it vapor-locked on me and I had to wait until night for it to cool enough to run again. An old codger on a porch across from where I stalled told me he sees it all the time, because of the heat and the slow limit as you go through town. In fact he told me that I had a 454 with vapor lock before I knew what it was or what was wrong with it, and this from across the street!

Mike, in about half an hour and for about $10 you could be running cooler.

Just swap out the thermostat for a cooler one. I'm running below 180 on the highway at 68 mph / 2600 rpm / electric fan on, though it's flat here except for the bridges mostly.

Sounds like a plan, Glen.
