What are the torque specs for an exhaust manifold?
Install the exhaust manifold, NEW gasket and bolts. Tighten Tighten the bolts a first pass to 15 N·m (11 lb ft). Tighten the bolts beginning with the center two bolts. Alternate from side-to-side, and work toward the outside bolts. Tighten the bolts a final pass to 25 N·m (18 lb ft). Tighten the bolts beginning with the center two bolts.
What kind of threadlock do you use for an exhaust manifold?
It is a 2004 with a 5.3. Apply a 5 mm (0.2 in) wide band of threadlock GM P/N 12345493 (Canadian P/N 10953488), or equivalent to the threads of the exhaust manifold bolts. Install the exhaust manifold, NEW gasket and bolts. Tighten Tighten the bolts a first pass to 15 N·m (11 lb ft). Tighten the bolts beginning with the center two bolts.
How many bolts do I need to tighten an exhaust manifold?
Tighten Tighten the bolts a first pass to 15 N·m (11 lb ft). Tighten the bolts beginning with the center two bolts. Alternate from side-to-side, and work toward the outside bolts. Tighten the bolts a final pass to 25 N·m (18 lb ft). Tighten the bolts beginning with the center two bolts.

How big is an exhaust manifold pipe nut?
The exhaust manifold heat shield bolts go on at 80 inch-pounds (not foot-pounds), the pipe-to-manifold bolts go on at 26 lb.-ft. and the manifold pipe nuts spec out to 26 lb.-ft.
If you add any lubricant (say a Never-seize type compound) then the torque specs are lower by at least 10%. I also searched around for torque specs on bolt sizes. Again depending on the grade of the bolt, torque specs will vary. Here’s a link: Botl Torque by Grade I believe the bolts are 10mm x 1.25mm thread count.
Is it possible to retighten an exhaust manifold?
If the studs etc are in very good condition then you could try undoing & re-torquing them. However due to the materials and heat cycles these parts go through the studs are often very tight or seized up. To repair this you’ll have to be prepared to remove and clean up all the threads, or just buy new studs and replace them along with the nuts.
How big are the bolts on a botl manifold?
Here’s a link: Botl Torque by Grade I believe the bolts are 10mm x 1.25mm thread count. Might be 1.5mm thread count. As for the sequencing. Start in the middle of the manifold and work outward, alternating side to side. Also move in steps to your final torque setting.
The standard is to use 20 to 30 foot-pounds of torque. Older engines often fall on the lighter side of the equation, so use 15 to 20 foot-pounds of torque if your engine is 15 years old or older. Some manifolds house different sensors and plugs, such as a check valve or exhaust plug.
How much torque should intake manifold be?
Intake manifold bolts and head studs/bolts have to be torqued in a certain pattern and to a certain torque spec in order for your engine to work properly. Intake manifold bolts on SBC engines should be torqued to 30 lb-ft in a two-step sequence.
Which is better PACCAR MX 13 or 15L?
The PACCAR MX-13 engine provides trucks owners up to a 400 lb weight savings compared to a 15L engine. • SUPERIOR PERFORMANCE & QUIET OPERATION:An MX engine’s broad torque curves require less shifting, and the quiet operation improves the driving experience. SPECIFICATIONS CONFIGURATIONINLINE 6-CYLINDER
How much torque does a Paccar Trans fastener have?
Paccar changes clutch and engine to trans fastener torque all the time! Clutch I usually go with new lock washers and 45 ft/lb on M10 bolts. Engine to trans I use blue threadlocker and 50 ft/lb on M10 bolts. KW has service manual for the new style trelleborg motor mounts so I attached that also.
What’s the life of a Paccar MX engine?
Press play to see power in action. The PACCAR MX Engine boasts a B10 design life of one million miles in linehaul applications. This means 90 percent of PACCAR MX Engines will log up to one million miles without a major overhaul, almost double the life of comparable engines.
What are the torque specs for a mx-13 truck?
FdEF and Oxbow Thank this. When all else fails, you can never go wrong with universal bolt torque by thread size, pitch size and bolt hardness. Only time you really need to defer from this would be everything inside the engine, cylinder head, top end and bottom end are torque turn specs or tty.
