Matt _Aero top_ Posted November 13, 2007 Share Posted November 13, 2007 My sups recently started making a horroble sound when i start it up and its cold , sometimes it does go away when its warmed up or been run for 20 mins or so , or if a spray abit of WD40 on the belt near the crank pulley making me think its either the belt thats fooked or the crank pulley , So my question is how do i check if the crank pulley is nackered , is this just a visual check or what ? I've done a search but i'm useless ... lol Please help me .. Link to comment Share on other sites More sharing options...

rovervi Posted November 13, 2007 Share Posted November 13, 2007 if its a wuuring kind of noise my money would go on the power steering pump they are often noisey when cold as they age Link to comment Share on other sites More sharing options...
Konrad Posted November 13, 2007 Share Posted November 13, 2007 I wouldn;t spray WD40 on belt :S Try to locate sound, it can be crank pulley and you do not want it to split when you doing 70 mph! Link to comment Share on other sites More sharing options...
Jake Posted November 14, 2007 Share Posted November 14, 2007 Matt, Paint/draw/crayon/whatever a white line on the front of the crank pulley. Make sure the line crosses the inner and outer ring - ie it goes across the rubber joint between the two parts. Then check it after it next squeals and see if the outer part has moved in relation to the inner part. If it has moved your crank pulley is fooked and needs replacing ASAFP. Do not under-estimate how important the crank pulley is. Apart from driving the water pump it also drives the power steering pump. You wouldn't be the first member to crash his Supra when the crank pulley failed, leaving you with no power steering. . Link to comment Share on other sites More sharing options...
movistar Posted November 14, 2007 Share Posted November 14, 2007 Replace the belt if its cracked up..if not a little trick is use a dab(blob using a small brush) of silicon grease on the v-belt side ( it will make its own way round when running) and this will give a longer temp fix. Like Jake said with the damped crank pully. Link to comment Share on other sites More sharing options...
