Topic: Winterizing with RV Red Pop

Author Message Prev Topic | Next Topic  estame6 "Seaman Recruit" Joined: July 12 2007 Posts: 7 Posted: October 19 2008 at 15:23 | IP Logged I have a 30 foot 1988 sea ray with 350 inboards and last year I successfully winterized the engines by emptying the blocks and exhaust of all water, removing the thermostat's and sucking through about 6 gallons of RV antifreeze till it came out of the exhaust and some. My question is am I doing any damage to seals or other internal engine components by using this type of antifreeze? Many thanks for any information... __________________ Estame6 Back to Top    estame6 "Seaman Recruit" Joined: July 12 2007 Posts: 7 Posted: October 20 2008 at 17:25 | IP Logged Just as a note.. I have a bit of a problem just draining water out of the block, I know some engines that lay at an angle, its tough to get all the water out, not that it would crack the block but why take the chance. The other is, all those places where the hoses connect to areas where water could lay in castings etc. It's just too big of an engine to screw with. I just use the -50 pink stuff I buy from TSC, I shut the intake valves and suck it through the strainers. I was always told to warm the engines before to make sure the t,stats are open. It takes few minutes to remove them. Again, emptying the blocks while in the area also doesn't take too long and prevents the watering down of the A/F. __________________ Estame6 Back to Top
