New Thermostat New Hoses New Radiator

Anyone know why this may be spraying in this location? I’m not a DIY’er so I didn’t even have a socket wrench to remove the engine cover to look.

So in being pre-emptive, I’d like ideas before my mechanic may blame it on something else after I’d gone to so much trouble and expense to secure my cooling system. Yes, I also have a Falconworks brass T.

Anyone? Thanks in advance!

See the spray mark (residue) on the engine cover, above the hose? That’s near the thermostat housing, right? (At the end of that big hose under the engine cover?)

 

....maybe take off the engine cover and have a look.

 

Yeah.. you need to remove that cover. Its a tiny socket, 5,6 or 7mm I think. Deep one and you can pretty much just use a socket and your finger cause they are not on tight.

But did you clean it? That almost looks like a drip of something from above, like a drop of oil when doing an oil change for example. Or can you see it actually spraying? If so, then probably a pin-hole in the coolant hose.

 

6 mm, had the opportunity to try sizes the other day since I, too, never remember the right one…
