Pressure washer -- winterization?

[CHDinCT]

I put mine in the basment last year.

Mine goes in the basement each year too. No problems with cracked pump from feezing, but after 10 years use, the pump was about shot. It was a homeowner model with a decent Briggs 6HP Intek engine that runs fine, so I just bought a new Comet pump from Northern tool - AXD2527. Was on sale and free shipping. Works real nice and one of the easiest jobs I've ever done - unbolt the old pump, line up the keyway on the engine to the new pump and bolt it right up.

I have a Culligan water filter fastened to the handlebars. The water goes from it through a piece of garden hose to the inlet on the pump. I use quick-taches on all of my hoses. When it is time to winterize, I dump the water out of the filter. The element still has some water in it, so I'll have to dump water out again in a few days. I disconnect the high-pressure hose and roll it up drained for the winter. I run the engine just long enough to expel the water out of the pump outlet. I disconnect the garden hose from the filter and pour a few ounces of auto coolant into the hose. I pull the starting rope with the switch off until I see colored auto coolant coming out of the pump outlet. So the water should be out of the pump and the coolant should be in the pump now. Then I pour a couple more ounces of coolant into the garden hose until coolant comes out of the pump outlet without me pulling the starting rope. So there should be enough coolant in the system now. You can use pre-mixed auto coolant (easy) or you can mix your own 50-50 or maybe a little stronger. Don't use RV antifreeze. Auto antifreeze lubricates the seals better.
