240zip Posted December 6, 2010 Share Posted December 6, 2010 On my engine with an after market aluminum radiator, we noticed that with the fan clutch, the plastic fan actually bows forward about 3/4" which is just enough to touch the fins at 7000 RPM. The option we're looking at is to swap the OEM fan and fan clutch with an after market low profile fan. This is our first option and is being done as the 'low cost option'. It seems the best option is to go with an electric fan and shroud with a temperature switch. The pictures aren't great, but you get the idea. It was a fairly stock set-up (mounts, engine, etc). Has anyone else had this problem of fan flex? Quote Link to comment Share on other sites More sharing options...
BluDestiny Posted December 6, 2010 Share Posted December 6, 2010 (edited) I remember reading a thread where someones fan grenaded, probably from flex and age,and put a gash into his radiator Edited December 6, 2010 by BluDestiny Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted December 6, 2010 Share Posted December 6, 2010 I would get an electric fan, preferably a kit that contains the temp probe and switch, so it's all automated. You'll never have to worry about it again, and it gets rid of that stupid stock clutch fan sound. Quote Link to comment Share on other sites More sharing options...
240zip Posted December 6, 2010 Author Share Posted December 6, 2010 we're looking at ones from JEGS and perhaps some custom modification of the JEGS shroud with our TIG Quote Link to comment Share on other sites More sharing options...
aarang Posted December 6, 2010 Share Posted December 6, 2010 I know this is a dumb question, but are you sure the clutch in the fan is working correctly. Unless your car is running hot, the fan should be "coasting" at 7K rpm. Does the fan make alot of noise? The clutch may just be locked up.

z2go Posted December 6, 2010 Share Posted December 6, 2010 I second the idea to invest in a good low profile electric fan. Free up a little horsepower, never worry about a fan clutch going out and destroying the radiator... Quote Link to comment Share on other sites More sharing options...
mario_82_ZXT Posted December 6, 2010 Share Posted December 6, 2010 Are you sure the fan clutch itself is hitting the rad? If it's just the fan, later cars used different offset plastic fans. A local guy here has also mounted the fan spaced out with washers on the backside of a clutch before for clearance. Quote Link to comment Share on other sites More sharing options...
