Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Despite several sections showing this drain plug being removed, they never mention it being installed (despite it being obvious it was replaced) and give no torque spec that I can find.

Factory info shows the coolant drain as using a "gasket" - which is actually an O-ring.

Suggestion
If it's not plastic - then I'd determine the size/grade of the bolts and use standard torque values for that size/grade bolt (Google for it..) I'd still be inclined to use some Loctite on them.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1Original post

I’m new here so not sure if this post is OK. Have a 2011 987.2 Cayman base. Looking for makeup torque for the three screws that attach the belt pulley to the water pump. Also looking for proper torque for coolant drain plug. I have posted on three other sites but no responses.

POST 2Original post

Hello Chip, These are the only water pump related torque settings the factory manual provides: Questions: Are you reusing the old water pump pulley? Many replacement ones come with a new pully. If you're reusing the old one - I believe it's plastic and in lieu of torque specs, I'd tighten them snuggly after putting some LocTite BLUE on the threads, then let it sit overnight. If it's not plastic - then I'd determine the size/grade of the bolts and use standard torque values for that size/grade bolt (Google for it..) I'd still be inclined to use some Loctite on them. The 987.2 motors aren't known for losing water pumps very frequently - so chances are it's the original one that's on there. Factory info shows the coolant drain as using a "gasket" - which is actually an O-ring. I'd strongly suggest replacing the O-ring. Despite several sections showing this drain plug being removed, they never mention it being installed (despite it being obvious it was replaced) and give no torque spec that I can find. Since an O-ring is used - the following that Google found at Pelican might be useful: The coolant seal isn't made by compressing the drain plug against the engine block, it's made by the O-ring. All the torque has to do is prevent the plug from untreading and falling out. There were a number of other returns from my Google search - but a lot of it looked like guesswork on some forums. The ones that did look like there was something behind the postings - mostly gave the values Pelican gives. Good luck, let us know how it turns out. HTH BTW - I'm moving this thread to the correct subforum for it - it fits under DIY/repairs..
