Temperature D24TIC

[Eli]

I guess your right, the first thing I should do is make sure my temperature gauges is reading accurately. If you are having good results with your thermo switch, perhaps mine is broken.

Thanks for the advice! I'll let you know how it goes.

240diesel- this is very cool! Some great data on D24 engine temps!

Did you ever take any measurements towing a trailer uphill in hot weather?

I like to follow a somewhat arbitrary criteria I found in an old Diesel Technician textbook defining a "sufficient" cooling system as keeping the engine under 100C under all conditions in which it is used- including towing uphill in high temps. I think this makes sense because it would (theoretically) allow you to run with plain water at 0psi in an emergency.

Unfortunately, this is a nearly impossible criteria for the stock D24T cooling system without any upgrades towing trailers in hot mountainous areas.

I use an engine watchdog TM-2 to monitor engine temps. It doesn't log and has just one sensor, but it can be moved anyplace and has a nice audible alarm:

I also wire the audible alarm into the low oil pressure light, and a float switch in the coolant reservoir.
