if you lived in Minnesota or Michigan I'd think about taking it to a shop, but in California the bolts should not be frozen. I've changed the motor mounts on several cars, including the SVTF with no problems. squirt the bolts down with liquid wrench if the don't break loose right away.

piece o' cake buddy.

Also, when you pull the bolts out of the mount, keep track of which one goes where. I didnt and ended up gauling a bolt because I put in a bolt that was too long.

DIY man!

do it carefully though.. i got impatient and pried on the bracket that holds the mount and broke it.. had to spend some extra $ to get a new one at the dealership.. but almost nobody has made that mistake

DIY. Just adjust the jack a little up or down to release the binding on the bolt. That's what happened to me. I had the jack supporting the engine but thought the bolt was bad so I kept wrenching on it. POP. Crap. So now I have a lock washer and nut on the new bolt.

And be carefull when you tighten these down. They will strip easy with too much umph. It's all soft metal. Rent a torque wrench.

I live in MI, the car has gone through 4-5 winters and had 88k miles on it when I did the rear mount on my own. No problems here when I did it. Been like a month or so now and no issues with the bolts

guys guys guys. i did them myself. on my car that has over 100k on it. and has not been garage kept in winter. the bolts only have 35 ft pounds for mounting to the frame and block. and the main bolts get torqued to 80 ft lbs. so its rather easy to work on.

on top of this the big drivers mount will ned like an inch or something cuz its huge.

but yeah i did it with hand tools and a cordless impact. no issues here.
