Removing manifold bolts - Niall - 02-01-2012

At the weekend I'm going to be swapping my exhaust manifold at the weekend and just want a bit of advice on getting the bolts out. I've done one before and the bolts came out easy but the engine was out so wasn't really a problem if one snapped as I could drill it out.

Any tips on making sure they come out with ease? I was thinking about putting a bit of heat on them then cooling them to try and crack them off first but not sure if this will make them more susceptible to rounding?
Cheers guys!

What i usually do is get the engine nice and hot first but then your likely to burn yourself lol

Lots of swearing and anger needed for those bolts when the engine is in.

Use the sockets that are same shape as bolt, i dont know the exact name, such a noob.

like these

Not these

Less chance of them rounding

Yeah was going to use 6 point sockets.
Im going to start soaking them later today for the week then heat them just before I do them. I would actually cry if one broke or rounded!

Going to wish you luck also as i'm guessing you're removing the subframe to fit the Gti manifold. when it comes to the bolts on the front suspension legs, remove the tall smaller bolts and not the big bolt, as they're normally seized and snap. I've snapped one, luckily was on a scrap shell. The other thing i would say is the four bolts that are under the floor plan make sure you don't cross thread them as both times i've refitted them at least one of them has been a pig to get to thread in easy, i have no idea why.

Nope not going near the subframe hopefully. Theres a easier way of doing it which is tight but I reckon I should be able to do it!
