Apu coolant use

Does anyone have a Thero king Tripac with the arctic package?
If so,Does it use slot of coolant.Im seeing a loss of coolant in my truck.

Thanks

 

After the initial instal, and topping the coolant back up, u shouldn’t see much of a coolant lose due to the apu

 

What motor does your truck have? How many miles?... I'd do a pressure test on the system then check it from there. I'm assuming nothing is leaking onto the ground?

 

Also, open the oil fill when the truck engine is running hot and watch for steam.

How much coolant are you losing?

 

345000.No visible sign of leaking

 

How much coolant are you losing in how much time? You might have a leak directly over your exhaust, or an internal block leak.

 

Might be burning it, does it have EGR cooler DPF system?

 

Yes
