Cold weather warming up issue

Its very cold here right now and when my tacoma is warming up there is a strange rattling sound near the driver side part of the engine. Probably doesn't have anything to do with the cold, but anyone have an idea what might be making a similar noise in that area of the engine? It goes away once its warmed up

 

Something is probably loose. Check the noisy area for loose bolts and connections.

 

A little heat shield on the side of the engine above the alternator? Not much there on that side to make noise. Could be just a stiff wire rattling around. Time to pop the hood in the cold and investigate. Could even be a block of ice.

 

Are u sure its the drivers side?
The 05s-06s had a rattle from the air intake where it goes into the pasenger fender.
When cold it would drive me crazy.
There was a TSB on it but even after the dealer worked on it, it still rattled. Added some sticky back foam insulation around it and no more rattle.
Otherwise...what the other guys said to do.

 

That was my guess. Probably a heat shield somewhere.

 

Yeah I've had that air intake rattle already and took care of that, thats why I really seem to hear it more on the driver side it seems. I haven't got to pop the hood while its doing it yet, kind of intermittent. I'll investigate more when I can pop the hood while its going on

 

I've noticed the same thing on mine but I haven't investigated it yet. Sounds like something plastic though and it only does it if it's below freezing. Goes away in like 30 seconds though.

 

yeah bud same as mine, really weird. Are you hearing it on the driver side as well? Or passenger side?
