Engine Mounts - The 1947 - Present Chevrolet & GMC Truck Message Board Network

crsgmc · 07-02-2018, 12:44 PM

I have been reading this board for quite a while but this is my first post. I am replacing the engine on my 1996 GMC K1500 with a new GM crate 350. I am about half way done and things are going well. My question is that the motor mounts have a secondary bracket on them in addition to the standard clam single motor mount. The passenger side is missing this second motor mount bracket. What purpose do these serve. I checked GM's web site and I did not recognize the part in the schematic. By checking the numbers on the old engine, it is not the original engine in the truck. I don't have much history on the truck. Maybe someone can shed some light on the subject, like the part name.

I'm assuming you're talking about the reinforcement rods and brackets that connect from the engine mount brackets to the bell housing cover since this is a K-truck. Correct?

Thanks for the reply. I should have provided more information. The bracket mounts to the part of the engine mount that is attached (bolted) to the engine. It has two holes one for a tab shown in the picture and a second hole that is threaded to be bolted to the engine mount. I am starting to think that this is a bracket for mounting something.

It might be for a bracket for trans cooling lines.

Maybe that is what it is. My truck does not have transmission cooling lines because it a standard five speed transmission. Because the engine is not the original one in the truck, maybe the engine was out of a automatic transmission. It could also be that GM just puts it on all the trucks, but it is unused on the manual transmission.
