Does anybody know why this is happening? Ever since it has gotten cold, when i start my car it will squeak really loud. the first time i heard it i got under the hood and took a look. everything seems fine. it seems to be the tensioner, i sprayed some WD40 on it and it instantly stopped. now if i dont spray it before i start it it sqwueaks and when i do, it dosent. its only been doing this since its goten below approx 35*F. This past summer i put on a 3in pulley and stage 2 belt, went 6 months with no noise, now noise. Anybody have a clue?

Thx in advance

 

things expand when they're cold. should go away once it's warmed up.

 

fixed

 

thats what i was thinking but its so damn annoying. thx

 

well to be fair water expands the colder it goes below 4C (if it didn't lakes would freeze from the bottom up and we wouldn't exist)
