"A fully charged battery will only produce 40% cranking power at 0°F (18°C) even if the battery is new and in good condition."

I'm purchasing two pad heaters for my Cummins.

You may want to check the current draw on each unit if you plan on running them all at once so you don't wake up to a stone cold engine. Cheers.

so in your opinion... would you rather have the "stock" block heater, or the pad?

Question for dieselenthusiast: Are you affiliated with that company in any way? 3 threads in one night is a bit much.

Be careful with those battery heaters,some years of KJ's have a battery temp sensor and it's located were that heater would go and will confuse the PCM which has the voltage regulator and may not recharge the battery at all.

If a battery only has 40% of it's power at 0 degrees,simple solution is to get better/more powerful battery.I kinda doubt the CCA's are only 40% of max power a 0 degrees,a battery on it's way out sure but not a good battery.My battery was still putting out over 1300 cca's the other day when it was -10 degrees outside,tested it since I was curious to how many cca's it had in the deep freeze compared to warmer temps.

The above link shows step by step installation with pictures, Unfortunately its to cold here to pull off the skid plate and snap pictures. Exposed skin freezes in 30 seconds or less and sticks to anything metal.

The block heater on my CRD burned out and it looked like a total b!tch to replace. I got the wolverine stick-on pan heater as a substitute. The model 16, 250 watt was the biggest one that would fit on the flat spot on the bottom of the CRD pan. It gets the oil warm for sure (~120F), but doesn't get the whole block and head hot like the stock block heater does.

Q: How does a Pad Heaters do a better job of Heating the engine than block heaters or tank type heaters? A: Pad Heaters put Heat into the oil supply. HEAT RISES to warm important INTERNAL components. Q: Are the pistons included in the list of Heater INTERNAL components and if so what temperatures are they warmed to? A: Pistons are generally warmed to 30°C (85°F) or so as governed by variables in engine type and design. Q: Will a Pad Heaters raise an engines coolant temperature? A: Remember HEAT RISES off the heated oil supply. The crankcase walls along with the cylinder wall, the outer block wall and the coolant between them create a very effective barrier to the loss of heat to the atmosphere. Only a small amount of Heat is absorbed by the coolant resulting in a 15-20° increase in coolant temperature.

Depends if you can get a bigger pad on the pan. 400W (stock) beats 250W any day, so unless you get a 500W pad, stock is better.
