Wondering where leak is

 

[MelsRegal]

rent a cooling system pressure tester.

I will, thanks. Does it appear possibly from radiator cap filler T and hoses?

 

[MelsRegal]

it's possible but telling from a still photo is not a good way to diagnose a leak.

Get the car up to operating temperature. While parked, have someone rev the engine a little while you look where the leak is coming from.

And of course use a clear shield in front of your face just in case, or some sort of protection.

Learning curve here. So the radiator fill and overflow is in a hose? Looks like a phenolic/plastic device and probably has a hairline crack as hose clamp(s) have been changed and corrosion residue is visible there. But of coarse do the testing as afore advice states.

If that was mine I'd install new hoses, match new clamps and fitting. Appears it's been there many years now. Car may not be worth bothering with though💵

Spot on. It was the doo dad the radiator cap screws onto. Only dealer carried it and made a mistake on pricing. Charged me 28.00 after quoting 48.00. Thanks for comments
