Im going to be winterizing my SR 185. It has a 4.3 mercrusier. It has 5 drains to remove the water from the hoses risers and block. I plan to drain all the water and remove the thermostat. Then suck antifreeze through the muffs while running the engine. Is this a sure way to make sure antifreeze has made it to all parts of the system??. If I dont remove the thermostat how would I know for sure that antifreeze has circulated everywhere??
Thanks for any advice!
Im Sorry!, I'm sure this has been covered but I cant seem to find it
