Fluid leak/winter problems

Hello Hello! I live in Minnesota and my bus from south cali is experiencing its' first real winter as I demo it ahead of the conversion. It's now cold enough that I wasn't able to start it up the last time I went out there. I purchased an espar/eberspacher hydronic heat system to install at some point but was hoping somebody could link me to a cheap/easy temporary product for warming up the engine for better cold-starts since I won't be able to install the heater for a while yet.

I've noticed some fluids accumulating underneath the engine compartment. It wasn't leaking before and I have been running it, but not driving it. One fluid is kind of red, the other is a yellowish brown. Can anybody tell me what fluids are leaking, and how to fix it? lol

P.S. - which forum is the best for asking about my air compressor/fuel tank fittings? not sure where to ask those questions. Thanks!

This is the heating kit I purchased if anybody has any advice on installation/implementation. I'm gonna try for radiant floor heat and plan on leaving the original coolant lines in for the defrosters.

Red most likely ATF leak, yellowish brown, oil.

Trace the transmission cooling lines that run from the transmission to the cooler.
Some busses use the radiator for trans cooling, while others have a separate/remote cooler.

From your pic, it looks like the other leak could be the oil filter. Wipe the body of the filter free of oil, and then try tightening it carefully. You'll need to run it a bit after tightening to see if that was it, or if it helped. If not, more evaluation might be in order.

Good luck, and post up what you find...

a temporary preheat solution could be a magnetic oil pan heater?
see if your block has the element heater(brain dead for real name for some reason right now). block heater?
some have it already installed and just need the cord, but your engine is already tapped for one if not already there.
being a cali bus it might not be there.
either one you will need 120v power available.
i have used torpedo heaters blowing under construction to get things warmed up but you also need 120v for that.
for the leaks i would clean everything up good and maybe put a clean sheet of cardboard under the area and run it and keep an eye on things but it definitely looks like the oil filter isnt tight
good luck
good luck
