NBR Posted May 21, 2006 Report Share Posted May 21, 2006 I got a noise coming from the engine bay sound abit like over reving... but it coming from the AC. I know this as the noise is only there when the AC is on.. but goes as soon as i turn the fan off or AC off....Does anyone know what it maybe? How it can be fixed?Im thinking the AC may just need re-gassing, but any suggestion will be greatly recieved.NeilIts a '51 reg GTi if that makes any difference. style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> Quote Link to comment Share on other sites More sharing options...
bossjohnc Posted May 21, 2006 Report Share Posted May 21, 2006 Well if it's never been regassed, it needs regassing!Could be the radiator fan though - the a/c rad puts out a lot of heat. Quote Link to comment Share on other sites More sharing options...
NBR Posted May 21, 2006 Author Report Share Posted May 21, 2006 The radiator fan: is that the big one behind the main radiator? Or is there another fan? The noise is there but the fan is not on at that moment. Quote Link to comment Share on other sites More sharing options...
bossjohnc Posted May 21, 2006 Report Share Posted May 21, 2006 Hmm.. good question - pretty sure there's only one though because of the placement of the a/c radiator.Could it be the clutch release bearing? (for the a/c clutch). Kind of a tinny rattly noise that would be... Quote Link to comment Share on other sites More sharing options...
Cliveski Posted May 21, 2006 Report Share Posted May 21, 2006 Well if it's never been regassed, it needs regassing!Would that cause a noise?The A/C on my Fiat Bravo is a bit noisy - if it's the clutch release bearing (a/c clutch) is there any way I can test it? also what would a ballpark repair cost be?

Not having one done wouldn't make your A/C noisy, but consiquent damage through not servicing it could cause something to make a noise I guess...

NBR Posted May 22, 2006 Author Report Share Posted May 22, 2006 Ok a few people have looked at the car tonight... seems to over get upto 100 and the fan never cuts in... Athough the 2 pipes to and from the rad are hot and flowing... its been suggested that it is the fan switch... so hopefully not a too bad repair bill...No idea on the AC though yet... that will be invetigated tomorrow...
