Re: 55 years ago I was given this USAF 54 3100
Sorry was thinking you were referring to chassis cleaning. My issues with engine overheating has been resolved although i find the very powerful SPAL racing fan noise a bit annoying. Fan pulls like 40 amps and required all new HD wiring and breakers. Its really loud but only needed intermittently at slow street crawl speeds or when stopped. I swear its so powerful it pulls me forward like an airplane propeller.. Yesterday was first time i had opportunity to cruise old town at like 5 mph with 70F ambient temp to try it out. Slowly got to 210F fan cut in and ran for like 45 seconds dropping temp to 190F. this lasts about 5 minutes and then the cycle repeats. This is acceptable but fan noise is not. Thinking of insulating hood. Its already rhino lined but not enough.

E - Fan Noise
My solution to the noise problem was to delete the finjer protection device .
This is VERY DANGEROUS SO Don't DO IT ! . Unless, of course......

Have you thought about using a variable speed controller for your Spal Fan?
Something like this? https://www.jegs.com/i/Proform/778/6...MdJKvwovtSHxlw |

Yes but its pulls many amps and cools so fast its just a minor problem. |

This controller will handle the amperage and can do variable speed as required to cool it.
Just a thought. |

I agree. The idea is sound, but some of the reviews on these aren't the best. May keep looking for a heavy duty one that can reliably dissipate the heat involved. HAve to admit the big spal fan works well - so well i think it drops temps below the 185 thermostat.
