Hi Guys,
Do any of you block the radiator shut or anything to warm up your engines more quickly and thoroughly before you pour the coals to it? I plug it in for an hour, then fire it up, engage pto, idle idle idle, then put in low and creeper low reverse and let it idle itself back out of shop while I go do something else for a few minutes and the oil filter is still not TOO HOT to grab (described in Engine Knocking Forum) and gauge says a little above 50. After moving or blowing snow it pops up tho. New thermostat did nothing. Or am I overANALizing again? Just that those crank bearing photos scared the hell out of me with so low of hours on it and a local snow guy burned up his skidder engine pistons cuz his staff wouldn't “waste time” by letting it warm up.
Thanks, Fido

Just one man's opinion; replacing the thermostant would do nothing to help warm-up unless the original was somehow defective. The hour plug in time helps starting but won't do a lot more to warm the engine. Partially or wholly blocking the radiator will speed the warm-up for sure, but don't be the guy who overheated his engine because he didn't pay close attention to what the engine temp was doing. A diesel engine doesn't generate much heat until and unless it is working. My guess is, a much longer plug-in time (say, 6 hours) would do more, but again, that's no guarantee.
As an aside, I doubt lack of proper warm-up was the cause of the spun rod bearing in my engine. The other bearings all looked okay other than evidence of bearing particles flowing thru the lube system and damaging them. But I'm no expert, and as I said, just one man's opinion.

are you using 15/40 engine oil vs a straight weight oil .15/40 will give you faster lubrication at colder temps.Where I used to work the fleet was powered with propane and they circulated warm water thru the regulator to keep the propane from icing up.,in the winter we blocked off part of the radiator to make the heaters work,but these trucks were old with I think 160 f thermostats.but you still had to keep a good eye on the temp gauge as it warmed up thru the day.

That's the old race car trick – having all the needles pointing straight up under operating conditions. That way you don't actually have to read the gauges to know what you have
