The saga continues...
New rad cap fitted and all temps fine.

Not used the car much over winter but 6 months from the start of this post, I have discovered a coolant puddle on the passenger side by the front wheel. I therefore fitted new ACT hoses and bled the radiator, but still have coolant leaking from the same place. The radiator is an ally one fitted by Power in 2008, 10,000 miles ago. Surely this can't be leaking after 10,000 miles?

I have the ACT hoses so don't think there is a bleed screw fitted.

How do I do a vacuum/pressure test?

With something like this http://www.amazon.co.uk/Cooling-Pressure-Universal...

I have a vacuum tool, but the vacuum tool requires dropping all the coolant out really. The leak even if minute shows up as the system wont hold a vacuum, the loss of which shows up on a gauge.

The good thing with the vacuum purge tool is if theres no leak, you stick the inlet hose in a bucket of coolant and it sucks it all back in replacing the air.... requires little or no bleeding.
Thanks. I'll see if my local garage has one thumbup
