Default cold start problem

Hi guys I have an 06 wrx wagon which I purchased over the spring. now that its getting cold in my state (last night it dropped below freezing) I'm curious as too why my car hesitated to start and when it finally fired I got a squeel coming from the motor. I'm going to change my fuel filter out this weekend and hopefully that helps witht the hesitation but I have no clue as to what the squeel could be coming from

The squeal is you timing belt, pretty common with subarus it seams like, it usually is heard where the belt is tight and temp is chilly, nothing that will cause any problems, you could stop by a shop and they may adjust it for you for free if ur lucky.

Squeal is not necessarily the timing belt, could be but not always. It could be ANY belt on the vehicle, so count in A/C and power steering as well. As for adjusting, you can adjust both A/C and Power Steering (also check for wear like cracking or crazing), however you cannot "adjust" the timing belt to make it not squeal. I have no clue where Ajschriack even got this.

A hesitation during cold to me, suggests a battery going bad. Extremely common. Colder temps=more power from battery needed to turn vehicle over.

OP what are the miles on the car? And also where are you located? (aka fill out your profile) Have the battery tested, possibly replaced. And depending on miles, have the timing belt replaced. As for the fuel filter, it is incorporated with the pump in the tank. Once again, depending on miles you might not need it at all. And to replace it is a bit of a chore.

The belt only squeals on cold start? Sounds like its perfectly tensioned. Its just at that point where its tight enough to not slip in most conditions so it'll have less bending load on the bearings making for less friction. Of course I'm used to racing a car where that 0.05 hp matters.

/\ What Leafy says.

A second or two of squeal is caused bythe heavy load on your alternator, after just starting and voltage being relatively low. You could just tighten the alternator belt adjuster, but I wouldn't.

Your battery may be on it's last, if this just started happening - start shopping for a fresh one.
