InitialDC Posted August 26, 2014 Share Posted August 26, 2014 I have a 07 LGT, recently I had the idler pully and belts changed due to maintenance. Lately he mornings have been getting colder and now I'm getting a squealing noise. I couldn't pinpoint the issusend but I assumed it was coming from the recently changed belts. I proceeded to tighten them, then wait till the morning to see if the same issue occurred. Which it did. I don't know where to go from here, can someone push me into the right direction. Thank you Link to comment Share on other sites More sharing options...
Max Capacity Posted August 26, 2014 Share Posted August 26, 2014 How much play is there in the belts ? I think 1/4 -3/8" is the Spec for that. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

InitialDC Posted August 26, 2014 Author Share Posted August 26, 2014 I didn't check when I tighten them but they don't have that much play. Link to comment Share on other sites More sharing options...
MNRZR Posted August 26, 2014 Share Posted August 26, 2014 Have you had the timing belt serviced? Including replacing idlers/tensioner? I had a similar situation and it ended up being the small timing belt idler. I tried to adjust the accessory belts first and it didn't help. Then I removed both accessory belts and started it for a short bit and the squeal was still there. Pulled the timing covers off and used a stethoscope to pinpoint the bad pulley bearing. Check the accessory belt tension against the specs that Max posted first. Link to comment Share on other sites More sharing options...
InitialDC Posted August 26, 2014 Author Share Posted August 26, 2014 I replaced the timing and the alternator belt. I'll check and adjust them again. Link to comment Share on other sites More sharing options...
scontivt Posted August 26, 2014 Share Posted August 26, 2014 Did you replace the 2 smooth, cogged and small smooth rollers, as well as the water pump? Link to comment Share on other sites More sharing options...
apexi Posted August 26, 2014 Share Posted August 26, 2014 Manual or automatic transmission, how many miles? Could be the throw out bearing on its way out if it goes away when you push the clutch pedal in Link to comment Share on other sites More sharing options...
InitialDC Posted August 26, 2014 Author Share Posted August 26, 2014 The milage is 68,600ish, and its a manual. I haven't pressed my foot on the clutch while it was making noise. I will do that tonight to give the car a chance to cool down. I only replaced the 2 belts, idler pulley and some small attachments that held them together. But not any rollers or water pump.
