SOURCE: Need to know roughly how long it would take to

Depends on your level of experience, quality of your tools and whether or not you have any frozen head bolts. The valve assembly and head come off as one unit on those. To clear the wires, emmision controls ect off of the top of the valve cover 30 minutes. remove valve cover 5 minutes (too scrape off excess gasket material. to remove exhaust manifold from side of head, (assuming no broken/stuck/stripped bolts 15 minutes with good hydraulic tools. To remove head (assuming all goes well and hydraulic tools, 15 minutes. To reassemble, double all times as surfaces need to be prepped and gaskets applied and proper torque on all bolts. It's an afternoon job if you ahve everything you need and nothing goes wrong. Typically add at least two or three hours of drilling and cursing to a head gasket replacement. and a trip for new drill bits and a tap (not beer) for the new hole you drilled.

What size torq bit on 2015 chrysler 200 front seat track


Torx head bits come in several sizes- 10, 15, 20, 25, 27, 30, and 40 for the smaller ones. Buy a cheap set of them, then you will have the right one. For the seat track application, I would expect about a size 25.

What is torqe setting for toyta hiace head bolts and do i have to change bolts


LOOK IN THE OWNERS MANUAL IT SHOULD TELL YOU THE CORRECT TORQUE. AND YOU DONT HAVE TO CHANGE THE HEAD BOLTS BUT YES YOU SHOULD CHANGE THE HEAD BOLTS. IF YOU TAKE A PIECE OF WIRE AND CONTINUE TO HEAT IT UP, YOU WILL EVENTUALLY BREAK IT. THE SAME GOES FOR BOLTS. EVERY TIME YOU USE YOUR CAR THE HEAD BOLTS GET HOT AND EVERY TIME YOU TURN THE CAR OFF THEY GET COLD. THE METAL CHANGES.
