We are having issues with the cooling system on our engine! There is supposed to be a pee stream out of the back of the engine, obviously cool water comes in, warm(ish) water comes out..but theres no sign of any water coming out, so presumably none coming jn either? So far ive been able to scrub around the grate over the inlet that draws water in, my initial thought was there must be a blockage, nithing changed, I've not examined anything internally yet. Done a bit of resesrch online, a few articles say to take the engine out the water and stick it in a bucket of clean water. Which isn't really something i want to do right away, also oretty sure that wouldnt fix the issue. Keen for advice and aby relevant resources or explanations, engines really arent something im confident with, please assume i know nothing!
