Coolant leaks

Post by henrym3 » Sun Mar 09, 2025 1:36 pm

Has anyone ever bought the o ring kit from USA with complete set of o rings for all the coolant pipes. About £30 with post. Way cheaper than buying complete pipes. I have various weeps especially round the g/b thermostat and header tank. Very minor (cup full of coolant per fortnight) but very irritating.

Well, I’ve sent for them anyway all made in Viton. £28 so we’ll see what effect they have. I’m into rubber atm just sent for a set of seals for the single vanos on the Alpina. With a bit of research I found that the cam locking kit and crank locking tool from when I did the chains on the 4.6 all fit the Alpina.

They arrived today, that’s quite quick for stuff from the USA. Just need to find a good day to fit them and sort a weep on the thermostat housing.
