Intake Manifold bolts that work loose - quick question
A general consensus seems to be the intake manifold bolts can work loose and cause a coolant leak. Which bolts tend to work loose - are they the bolts visible on top of the manifold closest to the firewall after you open the hood or are they not readily visible and closest to the firewall somewhere around the SAI tube clamp. Thanks in advance obviously never been there never done that - closest I've been is replacing wires without removing IM.

This is really a great question because I think my slight coolant leak is coming from the intake bolts working loose. I was able to get a wrench on the left front bolt and it was loose. Unfortunately, I think you have to take off the upper intake to tighten the rest of the bolts. If I end up doing that, I'll probably do the head gaskets at the same time.

My question wasn't clear so let me try again (I totally agree with the Locktite suggestion btw but I need to know where the loose ones tend to be located first). So here's my re-worded question:
Where are the intake manifold bolts located that people say tend to work loose and cause coolant leaks? Upper manifold, lower manifold, location, etc. Yes I am being lazy but looking for advice in case I need to plan to order new gaskets before tearing things down to see if a bolt or two is loose. Naturally what I'm hoping for is something like "take a 10mm swivel socket and an inspection mirror and find those 2 bolts on the upper intake manifold at the rear and check for tightness" (I don't even know how many bolts are at the rear against the firewall) :-)
Thanks in advance for your responses that make this a great forum.
