..DONT touch it :roll: May have been a good thing if I'd taken my own advice. BUT .. me being me, thought I'd flush the cooling system, seeing as its the one thing I havent done, and wasnt sure if the previous owner had. All went well, used motul coolant etc.. The next day I noticed the 'smell' of coolant when stopped at lights. Got to work and took a boo-beep. Damn coolant leaking from the themostat housing and/or hoses . :evil: This pissed me off cause I've always felt 'smug' about the hornet's condition >> never let me down, no oil or coolant leaks, no smoke, no oil usage ( apart from the norm ). And I am on my way to the WSB in the morning. Anyway, stripped her, removed the housing, new seals, clamps and sealer. NOW I'm happy Just seems odd that this problem occurred, seeing as I did not disturb anything in that region. Perhaps it was flushing that removed 'gunk' that was previously sealing components ? :? Has anyone come across this before?
