 Car overheated whilst in slow-moving traffic. The excellent Gavin Gray of Autotechniks Edinburgh discovered that the fans have seized. In addition the a/c has a leak. I understand that the fans operate as part of the a/c system; this and the fact that I don't encounter much slow moving traffic may mean that the fans have seized through lack of use. Has anyone else had a similar problem?

 Radiator fans have siezed?

Don't think anyone has posted on that before. The fan relay on the rad can be problematic though.

 Thanks Dave
Apparently the relay is OK. In fact one fan turns reluctantly and noisily. I'm no expert (can you tell?) but I would have thought this might be a more common problem in cool northern latitudes with little traffic congestion. I was hoping a 10p squirt of WD40 might fix them rather than the 800+ quid for 2 new ones! Silly me eh?

 My old Renault Espace had that same issue when I first got it. I took out the 'grill' and persevered with, first, WD40 then, second, aerosol white lithium grease. They'd also seized -- they're in a vulnerable location in front of the rad, same as the 2.7 C6 -- and, thus, had blown the 30-Amp fuses (one for each).

The motors' bushes needed freeing off first (the WD40), then lubricating for more longevity. Just spraying them and 'working' the fan blades back & forth freed-off one; the other wouldn't budge (the fan was turning on the motor shaft instead). So I worked the fan off the shaft and tightened the chuck of a cordless drill onto it, slowly rocking the shaft back & forth until it gave way.

Still working, a year and a half later.
