Should I warm up the engines to normal temp before running antifreeze through them?

Since we are on this subject, do any of you with the 3126 "fog" your motors at winterization time?? I spoke with a CAT rep who indicated that fogging was a must do item

He did not give me any idea as to how to fog the motors (of course i didn't ask). He was located in NC ( maybe SC, not sure ) and I had worked my way up to him trying to get CAT to participate in the recent overhaul of both of my motors (one at 260 hrs and the other at 750). The first motor was the famous broken valve (CAT's excuse was too old and lack of use) The second motor was due to a pitted cylinder wall. The CAT rep said the pitting was due to moisture that entered the cylinder. He indicated that had the motors been fogged, it would most likely not have happened?? I'm going out on the water tomorrow afternoon with the mechanic and service manager from my local CAT dealer to try and diagnose a strong oil smell and I will inquire about the fogging method
Any diesel engine i have ever seen has a heat exchanger and uses A/F in the engine already. just the heat exchanger needs to be drained of seawater and filled with pink af and the mufflers.
Why make simple things complicated? Just rig the bucket to hold 7-8 gallons of pink and run it through the systems. No need to drain anything. Run enough to make sure you clear pink coming out. If you're trying to save some pink, this is wrong place to do it. If you mess something up the repairs may cost thousands. It's not worth saving $20 worth of pink.
The fuel cooler, oil cooler, after cooler and tx cooler all get their raw water from the same source......The thru hull. Pink in-----Pink out viola, problem solved. My Cat 3126's and associated raw water components flush out with 6 gallons of Pink. 2 Gallons for the Gen and 3 for the A/C and that is probably overkill but Pink is cheap compared to an engine block or raw water component repair. There is really no other practical way to winterize. (well, maybe move the boat to Florida).Be careful here... there are also fuel coolers, oil coolers, aftercoolers and transmission coolers that can hold water after haulout.
I have cummins, and have not winterized a Cat....but I am pretty sure there are more than mufflers and h/e's. Sometimes the way a particular hose is routed can make a difference on how things drain too, do your diligence.
