is there any way or any companys that can test radiators.

ive had a slow water leak coming from the rad area, checked/double checked/triple checked all hose conections and yet its still leaking.

just feel a bit gutted if my alloy rad has let go on me and would like to have it tested just before i go out and spend a few pennies on a new one (piece of mind incase it is ok!)

only think is cant see half the rad with the intercooler etc all in there so ive stripped it off the car, just wondered if there is a company that can test it for me while its off the car, tried several places local and keep getting blank faces!

Cheers

Kelvin
