speedyg 16 Report post Posted June 27, 2012 Hi, I have just replaced the water pump and viscous clutch in my car, all is running good again. On startup the viscous fan is really noisy ie. going flat out and shifting some serious amounts of air. After about a minute it quietens down and sounds normal, but will get noisy when accelerating off from a standstill when cold. My question is, does this sound normal and is it just the new viscous coupling? It is a after market one from Millands, brand :Hans Pries Topran (sounds German ) I am tempted to put the old one back in which was working fine.

Neal 545 Report post Posted June 29, 2012 Should sound similar to a Holden 202 when it's good Quote Share this post Link to post Share on other sites
speedyg 16 Report post Posted June 30, 2012 Ok, all good then. I was reading on a few other websites that the OEM viscous is much quieter than aftermarket. I guess I will just get used to it. Quote Share this post Link to post Share on other sites
