Thread: Coolant leak

Same stuff sorted a head gasket coolant leak on outside corner of #1cyl for three years (one treatment only)...

I was thinking the same,but it's running so well,even in an hour traffic jam in heat and towing the boat no issues at all.......at first the coolant was looking a little thick but now thin and normal looking. The instructions said to put it in the radiator but I put it in the coolant reservoir, maybe this has worked in my favour as the sludge would have thinned and mixed before travelling through and to the radiator........just a thought....think I'll leave it alone and just monitor for a while.
