This will be the second time that I have torqued down my intake manifold and am wondering if anyone knows where I can find intake manifold bolts for a 2003 5.3 stock manifold. I reused them the first time during my cam swap (had to pull the heads because exhuast shop broke off header bolts ), but this time I would prefer buying new ones. I cannot find any so far on summit, jegs, oriellys, autozone, or TSP, so if anyone knows of stock replacement bolts let me know please.

 

I get mine off eBay....usually stainless. Or I found a place... albanycountyfasteners.com

 

Just get some stainless ones at your local hardware or fastenal.

 

I mean it don't sound like a common replacement part. Are they reusable more than once? I reused them during my cam swap.

 

The intake manifold bolts get torqued to about 7.5 ft-lb (89 in-lb). They aren't torque to yield. You'll be fine reusing them. If you really want to replace them, the dealer parts counter should be able to get them. Or you can buy them at the hardware store if you don't mind them not being the exact same as stock.

There's always ARP as well.

 

reuse them. the intake is plastic.

 

I have like 20 laying around. You can reuse them a million times, the torque is so minimal.

 

GM#17122601 -Truck Intake bolt 4.8, 5.3, 6.0 SOLD AS A SINGLE

FWIW, There about $10 a piece too and it requires 10 total...

As mentioned, they are reusable.

 

I'm gonna go ahead and reuse them them. Thanks for the help, and saving me money!
