How do I find the right replacement engine??

If you're buying a used engine from a wrecker their software will tell them what engines are compatible to yours. You'd have to trust them on mileage and condition but to a point you can verify some of that before installing, like how clean it is under the valve covers, use a camera to check the cylinders etc.

"there software" is the 8th vin digit, that is all there is too it, that's what they use
any online seller will list the vin digit with there motor offered any worth there salt anyway
for instance vin c, vin z, vin t, vin f, etc
for instance here is 2,300 VIN C (L83) motors listed they can go in a pickup or a suv doesn't matter as long as the vin digit matches

There's also a year range that's compatible. In this case looking up used engines they only list 2007 and 2008. They used the same 8th digit vin letters beyond compatible years.

Our 2007 Tahoe is starting to have engine issues on a regular basis, and I think it’s time to replace the engine.

A LITTLE BACKGROUND:

This Tahoe was actually given to me by a family member and thus has significant sentimental value. We’ve only owned the car for 4 years, but its been driven all over the country and fell in love with it. It has 287K miles, has strong a engine, and has given us very few problems. Lately, I’ve been dealing with more and more issues and I know the older it gets, the more repairs it’ll need.

THE PROBLEM:

I don’t understand the process of buying a used/remanufactured engine.

Questions:

*My biggest question is how do I verify the mileage, or quality of the new engine?

*Where do i buy replacement engine from?




I livein Atlanta if that matters.

Thanks in advance for you help.

An engine from a salvage yard like LKQ will provide you with the odometer reading on the vehicle when it came into their possession. This does not necessarily mean that the engine has those miles after all these years. Could be more, could be less.

The salvage yard engine will have a warranty of some kind, read the fine print.

The 5.3 LMG engine was changed slightly in 2010. So if you wanted the same engine that yours came with, look for 2007-2009 engines. You can also run the lighter LC9 engine from 2007-2009 in place of your LMG.

So my question to you is, if it has a strong engine, why does it need to be replaced? How mechanically inclined are you?

the 8th digit is the engine code that was installed at the factory, this code means any matching 8th digit code vehicle engine is a direct swap, no ecm needed.
this does not mean that you could not swap any other engine, it is simply what is used for anyone that just needs another 100% compatible engine and that's all they want.
the 07-08 6.2l (vin 8) is a l92 and the 09-14 6.2l (vin f) is a L94 the vehicles will have a different 8th vin digit, although yes you could slap a l92 into a l94 vehicle (or vica-versa) but the ecm would need to be tuned or the original ecm would be needed. they are not plug n play

and to clarify yes certain year ranges have the same engine code, that has nothing to do with it. a vin 8 is a vin 8 regardless of the year, all you have to worry about is the 8th digit
