For a while now I’ve been having to top up the coolant because of a leak on the front drivers side of the radiator. The thing is I can’t see if it’s the bottom hose or the radiator leaking. Whenever I get a chance to look under the car it doesn’t seem to leak but then some days I park it for 10 minutes, come back and its pissed loads out. Maybe Im being stupid but why would it happen so randomly?
I’ve tried squeezing the hoses when it’s hot and under pressure but I can’t make it leak. I’ve even tried using a UV light to show the fluorescent die in the coolant but I still can’t see where its coming from. Any tips?
