Hi folks... got a 13 M59 which we are using for snow work this winter! It has the inline rad hose curculation heater, I'm not fimilar with these as are other machines have a blocker heater... when I tested it, after a few mins it was to hot to touch? And I'm afraid to leave it plugged in for long periods of time.. any experience would be great

Re: Inline curculation heater

It works just like a block heater (same heating element), it has an internal thermostat that will shut it off (just like a block heater) when it get to the proper temp.

As with any block heater it's best to either have it connected to a timer or plug it in an hour or so before needed. ;)

What he said, except I would add that the time required depends a lot on the wattage of the heater compared to the engine size, the ambient temperature, and the wind exposure. A small engine with a large 800 or 1000 watt heater might get the coolant in the block mostly warmed up in an hour when it's -15°C, but that heat still needs to "soak" before the oil in the pan starts thinning. A larger engine, outside in -30° or -40°C temps, exposed to the wind may even require a second, magnetic, heater for the oil pan but even a tarp draped over the vehicle can help keep the wind out.

Most test results I've seen came up with numbers between 2 and 4 hours. I split the difference with my vehicles and set the timer for 3 hours before I plan to start the vehicle any night the temperature forecast is less than -15°C. Typical overnight lows around here are -25° to -35°C in mid-winter but do dip below -40° a few times a year.

I also have heated battery blankets installed. They make a big difference too, especially with an older battery. Block heater and blanket get plugged into a very short extension cord under the hood so I only have one plug hanging out front.

Thanks gents!! Ended up installing a block heater coil type! Pulled a frost plug and prEssex the sleeve in... after talking with other folks, apparently those curculation ones work great however can burn out? As the machine is onsite all winter going to plug it in or rely on the timer just doesn't work... all are other kubotas have the normal blocker heater plugged in 24/7 so it just made sense!.. thanks again!!
