Customer Question

trying to winterize 2017 3790 Montana. Can't get anti freeze to the pipes
JA: Has your car been overheating? Have you noticed any leaks?

JA: What year is your Montana?

HI my name is Robert.....

IF the pump is running try and prime the line with a funnel, if there is air in the line the the pump can get air bound, you can also try and loosen the outlet on the pump and see if it will start to suck the antifreeze out of the bottle. Also make sure your battery voltage is above 11.5 volts or the pump can run but might not pump any water or the antifreeze. The water heater should be bypassed so that is good and you should be seeing the antifreeze, you should feel air out the faucets and then it will start to spit and then you will get flow... Let me know if you need more help.... Robert
