Torque Specifications

Updated: May 29



A list of torque specs for most things including the engine... If you're gonna do it - do it right!


The correct torque is especially important on cast aluminium engine components with steel fasteners - Most of these things aren't as tight as you might think if you were tightening them by feel and it's incredibly easy to strip aluminium threads with an overtight steel bolt. The hot side of the cylinder head around the exhaust manifold is a prime location for this happening.


Always clean bolt heads & exposed threads with a wire brush and WD40 before tackling them. If you can - wherever you have a steel bolt screwed into an aluminium thread, give the bolt a single tap with a hammer before undoing it to shock the thread free. If it gets tight whilst you're undoing it, screw it back in a turn or so then back it out again slowly to avoid snapping the bolt. Plenty of WD40 and take it easy.


The following torque settings are quoted from a popular range of workshop manuals; it's not a comprehensive list but hopefully it'll keep you right for basic servicing tasks. Most bolts around the engine are 10, 12, 14 or 17mm.
