ANTIFREEZE LEAK WHILE TRUCKS STAYS PLUGGED IN!!!!

[HOLSTEIN]

normally dont leave the truck plugged in for a long period of time, but with the temps really low and plowing contracts i need to be ready. this morning when i went out for bfast i noticed a dinner plate size wet spot (not puddle) under the truck right in front of the oil pan. after examination, its antifreeze. normally its only plugged in for about 4 hrs before i leave, but yesterday i left it plugged in all day and night. what gives? anyone else had this issue? thanks in advance...

Where is it dripping?in front of the engine? If so check water pump and Tstat seal
If drivers side check oil cooler.
If passenger side check htr hoses and core.

Then obviouslly check the Rad hoses...stupid factory clamps. And the block heater itself. Its on the rear drivers of block near oil filter.

I think its where the heat element goes into the truck.. Maybe???? Sounds probably but I have never looked at where this happens.

actually its dripping off the cross member right in front of oil pan (front of drain plug) ... there are some lines that run in a "U" that are snap clamped on it.. also about a baseball size amount from front right of truck... another site mentioned water pump about to go out? truck NEVER goes above 190*.. how would i know if its about to go out?

Im not sure. I know whenever I see rust and corrosion around mine I replace. Shortly after it has failed!! Thats just me though

You need to pressurize the system and just look for the leak.

not being funny, but how do i do that? it doesnt leak at all while driving/idleing weither its hot or cold outside...

Theres a tool that fits on where your radiator cap goes and it has a pump and gauge and you pressurize the system to whatever psi your radiator cap is rated at. Some leaks only leak when the engine is cold and been sitting for a while. I know Macks are known for that. You could probably rent the tool from your local auto parts store cheap.
