Hi I have problem with my Jaguar XJS and am hoping someone might be able to shed some light on it.
My 1992 Facelift XJS 5.3 V12 has developed a whining noise. This noise only happens once it has warmed up and the thermostats have opened. At tick over and gentle acceleration the whine occurs but seems to go on hard acceleration. On investigation with a stethoscope it appears that the noise is coming from the radiator. The radiator did have a new core fitted by the pervious owner 6 years ago.
How can a radiator make such a noise and is there an easy fix?
