tniss Posted November 3, 2009 Share Posted November 3, 2009 Just wondering what do you do to winterize your rig. Do you use antifreeze in your tank or do you just try to drain all of the water out? Also do you do anything special for the motor? Quote Link to comment https://www.bigmacktrucks.com/topic/11282-winterizing/ Share on other sites More sharing options...

Connect you air compressor to that cap and open that valve. Remove all intake and discharge caps. Then, with the entire system under air pressure, open one valve at a time, blow out the water, close the valve, and move to the next valve. Make sure you do this for all valves including tank fill and pump to tank. Also do the same with each drain valve including the main pump drain. You will sometimes have to wait on your compressor to catch up. Do this several times on all valves until you see no water being expelled when you open the valve. I hope this helps.

David Posted November 3, 2009 Share Posted November 3, 2009 We use a little RV water system antifreze (the pink stuff) in our presure washer pumps. I would think that would work in fire trucks also.

This is where the air comes in handy. In addition, don't forget to check the other important stuff- use a hydrometer to check the anti-freeze's low temp....Also don't forget to treat your fuel, STA-BIL for the gasoline or a diesel treatment.........
