Hey guys,I was looking in ~ the gasket sets because that the 3.4 v6 engine for my 2004 Impala and also noticed because that the input manifold it discussed replacing the bolts recommended.Has anyone heard that this? has actually anyone excellent this? Is it really necessary?I"ve heard of instead of the head bolts however the intake bolts?I desire to do sure before I carry out replace them. If it"s not really needed I won"t do it however if it is climate I"ll execute it. Not trying to it is in cheap, simply not spend any more money 보다 necessary, and also if intake manifold bolt replacement really isn"t needed then i won"t execute it.Thanks in advance!

Apply threadlock GM P/N 12345382 (Canadian P/N 10953489) come the threads and also Tighten the top intake manifold bolts and also studs come 25 N·m (18 lb ft).No cite of replacement.

What around the lower intake? Those room the ones that looks like replacement is recommended based on what was showing on autozone. Sent out from my iPhone making use of Tapatalk

Here what the says--Caution!
Maximum gasket power is accomplished when using brand-new fasteners, which contain a thread-locking patch. If the fasteners space not replaced, a thread locking chemical have to be applied to the fastener threads. Failure to change the fasteners or apply a thread-locking chemical may reduce gasket sealing capability.Caution!Use the correct fastener in the exactly location. Instead of fasteners should be the correct part number for the application. Fasteners requiring replacement or fasteners request the use of subject locking link or sealant are determined in the business procedure. Execute not use paints, lubricants, or corrosion inhibitors ~ above fasteners or fastener joint surfaces uneven specified. This coatings affect fastener torque and also joint clamping force and also may damages the fastener. Use the exactly tightening sequence and specifications when installing fasteners in order come avoid damages to parts and also systems.

ImportantAll reduced intake manifold bolts have to be cleaned, cost-free of any foreign material, and reused just if brand-new bolts room unavailable. Usage GM P/N 12345382 (Canadian P/N 10953489) or equivalent and apply come the old entry manifold bolt threads. ImportantManufacturer recommends the center bolts be completely torqued before the diagonal bolts to assure ideal seal ability. ImportantLower intake manifold bolts in place 6 and also 7 need to be torqued to specification using a crows foot type tool. Install the lower intake manifold bolts.Tighten Tighten the vertical lower intake manifold bolts (1, 2, 3, 4) in sequence to 7 N·m (62 lb in) top top the first pass.Tighten the diagonal lower intake manifold bolts (5, 6, 7, 8) in succession to 7 N·m (62 lb in) top top the an initial pass.Tighten the vertical lower intake manifold bolts (1, 2, 3, 4) in sequence to 13 N·m (115 lb in) on the last pass.Tighten the diagonal reduced intake manifold bolts (5, 6, 7, 8) in sequence to 25 N·m (18 lb ft) top top the final pass.
