Very unusually for me I got lucky today.
Got the nose of the 987.2 in the air and found the source of the leaking coolant.
Bottom left hose, everywhere else bone dry.
With a bit of 'slowly-catch-your-monkey' teased the hose off the bottom plastic T connection and the other end slipped out a dream from the radiator.
Somewhat surprised, and having caught 2 litres of coolant in old oil catch trays I scooted off to the OPC who happened to have the hose in stock (!) infact, he had ALL the front hoses in stock which indicates the 'popularity' of this fault!
£30 later back home with a similar cost of coolant in hand and it all popped back together.
Opened the engine up (again...) and opened the Burp Valve and poured in about 4 litres of neat OAT coolant topping the engine tank. Started the engine (no smoke, no coolant message) and warmed it up and up and up..and then all the hoses to the rads were hot, fans on, heater to fully hot so the system should be wide open to flow and air pockets dispersed.
New hose ok, everywhere else ok that I could see, so will test the car tomorrow and hopefully rejoice next week if the coolant level in the boot is steady at Full. I have just over filled it above the yellow MAX marker so I can actually see it!
So, 90% sure I've fixed the leak for £65, learnt a bit and feel better.
Soon will try my mod to the AOS/Vent tube.
ps, wish my wife looked that happy in my Boxster!
