New 2015 Ranger 25SC owner - Help! closed coolant mixing

Postby scuffy 2 on Wed Oct 10, 2018 7:09 pm

I recently bought a 2015 Ranger 25SC. I am now winterizing for the winter ahead in Wisconsin where temperatures can get to -30 below. My boat will be stored indoors but the building is unheated. The sealed system coolant that was in the boat was good to -11 below. The Owner's manual for Volvo Penta D3 advises to mix their VP coolant concentrate with distilled deionized water which meets water quality standard ASTM D4985. I am having trouble finding this kind of water and wonder if distilled OR deionized water type 2 would work. Can any of you help me with this - I would appreciate any help.

D4985 is a coolant standard. Distilled or demineralization water, as specified by the manufacturer can b added as specified to meet the standard.

There should be no difference, but however the manufacturer tested to meet the standard is ok with ASTM.

Follow the label and be fairly exact. More ethylene glycol is not better.

You mentioned that the building was unheatef. But does it have electrical outlets?
If it dies there are a number of small area heaters that you can use to keep the engine compartment a bit warmer.
We get down to -6 degrees in Southern Oregon but use three heaters in the boat’s cabin and engine compartment during the winter to keep temps above freezing.
