Hi guys, I need a little help, I’m a GSE Mechanic and work on equipment out at the Airport. We have equipment that run that needs some type of Sensor when a unit gets hot will shut down the engine so it doesn’t cause Damage to the engine or blow the Radiator. A lot of the Equipment use the Ford 300 6 cylinder engines that have been used for ever. Does anybody know of such a sensor that you can put in that would cut the engine off when temps hit over 220 degrees ?? Thanks for any help Todd

I have maybe a strange question for you. And you may not be from the USA, and laws and regulations may be different – but you sure you want to take on liability, should it be indeed the USA? esp for an airport equipment? I mean, it’s one thing to rig your home gas generator, quite different – airport/people safety and what not with terror obsessed country now?
I would suggest going through the cooling systems with new coolant, T-stats
and cleaning the fronts of any debri/obstructions. also check any fans work or belts
are good. 🙂College man, thanks for the tip.. the problem with this old loader is the engine is in a compartment and where you are working it up on top, it is the big L shape loader if you have ever seen loading big cans on an aircraft. sometimes it tosses or breaks a belt causing the fan to stop working, for were you work you cant see it or hear it go and you cant see the gauge from that angle, so I was thinking on using a fan switch that is designed to turn on a fan, but instead use it to cut the engine ignition when it reaches like 210 degrees so the radiator or engine doesn’t get damaged from over heating ?? I’m thinking the switch would ground its self at a set temp? 210 and ground the ignition to shut it down ?? any thoughts ??
If the switch will open on temp make it should work. I take it you have a coolant spot?
I would not ground the ignition. You may want to break the fuel pump circuit to cause a
no start condition this way if its cranked by whom ever your not loading fuel into the cylinders.
Keep us posted on your progress if it worked? 🙂Any farming in your region? I know many of the engines used by farmers are equipped this way. If they happen to use a tractor as a stationary engine to operate a well, they install a kit first that kills the engine at low oil pressure or high temperature. Check with the implement or stationary engine dealers.
As pointed out there may be something in the aftermarket that can help. If not, you may be able to track down a temp switch, I’m thinking of one that they use to operate electric cooling fans that you can stick directly into the radiator. You could then wire it up to the ignition or fuel pump circuit via relay to cut the circuit when it reaches that given temp.
Good luck with this one and keep us posted.
