the original manifold has a shroud with insulation in it. Does that shroud need to be on the dorman?? also, the insulation disintegrated upon removal,

No. Make sure to remove all of it. The dorman should have a gasket built into it.
746421
No it's not needed. If it had remained intact you could have transferred it but it's only there for noise suppression.

no it does not have to go back on it...mine fell apart so bad that it couldn't go back...just looks strange not being on there but truck has ran perfectly since mine was installed

Yes; There is a tiny o-ring that must be placed on the plastic piece that snaps into the top of the intake manifold. If it is not installed, it will cause the exact problem you are talking about. I learned after installing the manifold, then had to remove it and place the o-ring on, bolted it back on, problem solved.

I had the same problem. After using a wrench to get the whole thing off, then used more tools to get it apart, it leaked like a sieve after I screwed it back on. I'd like to know the answer myself because I bought a new one.

Wow. That's exactly the problem I am left with. I've re-visited my install as I kept thinking that there was something I wasn't doing right. You've actually helped me! Since the original sat flush now I'll dig out the old gaskets and see if it'll seat properly and re-use them. If you find a solution do let me know. Thanks. Jean

I would use this or some other sealant in a case where a replacement part is not available, but otherwise, you could probably pick up a used manifold at a salvage yard for under $50 and do the job the right way. I've learned that in the end, shortcuts rarely save any time or money.

The correct replacement is Dorman part #603-158. It is available through Amazon for $85.00. That is about $40.00 cheaper than if you were to buy it from Oreilly's. I didn't check any other automotive stores but they would more than likely be about the same. I hope this helps.

I used silicone sealant. You can pick up a tube of it at any hardware store. First I cut out a hole to make room for the solenoid, then I ran a bead around the gap between the shroud and the lens. Next I flattened the bead with my finger. Make sure you don't get any sealant on the lens itself or on the reflector.

The vent door actuator ( defrost to dash to floor control) is ACDelco 15-73952 is crosses over to a DORMAN P/N and $33 on amazon. Same actuator is used for the Blend control ( your issue ). the actuator is on the bottom side of the dash right side of tranny hump just under the vent cover. (2) 6mm bolts and unplug it... replace... about 15-30 minutes tops.

i did not use the black plastic piece, did not need it. I used the new alternator bracket however. Got everything back together with no issues

I would replace the vent cover first, because the back of the fantastic vent cover is open. Hope this answers your question

I would not recommend the dormans at all. They last 7 weeks on my truck. They are garbage. They are universal and will work on either side.

Yes. The dorman is a cheap imitation with poor flow and sealing. Get the ford part

No this is for the passanger side, the Dorman 520-302 is for the driver side. If you need one side replaced more the likely the other side needs replaced as well. This was the case for me. Hope this helps.

I carefully removed mine without damaging them and reused. There really is no need to get new gaskets. On my 2013 1200 sporty, you just stick your finger into the old slipons, and you will feel a lip. Just curl your finger and pull it out and reinsert it into the old one. These pipes are super loud and fun. Enjoy.

On the carb that I got the gasket between the engine manifold and the carburetor were not supplied. I used PermaTex (gasket compound) and the old gasket.

Absolutely, It comes with all Gaskets, Seals and O-Rings. Actually, more O-rings are supplied than you will use to replace only the manifold. Additionally, I will add that this Dorman part is of much better quality than the original G.M. part, reinforced at areas that are poorly made on the "genuine item". If properly installed, you will not be disappointed. ~Wally B.
