MONTE CARLO Need A Little Help From The Monte Carlo (Chevy) Gang.

Or Camaro, Elky, Chevy CCC engines in general.

Apparently there's an ESC Controller module or something located on the passenger fenderwell of the Chevy kind that has a BLH barcode sticker on it. These are found on Corvettes, Camaros, pretty much anything with a CCC system and Chevy engine in it in the mid-80s. Exact years I don't know, but it seems all the G-body Chevy-engined cars had the BLH.

It appears this BLH sticker came in all white with black lettering OR black with white lettering. Anyone know which years/models used which design?

I've made repros of both, just don't know what application they go to. Or if it matters.

Rock Auto is getting better with their pictures.

Just curious so pulled 85 Monte 305 and got this....

Basically this takes place of the separate anti knock sensor as this unit contains a piezoelectric crystal that senses knock and retards timing.

 

[78Delta88]

83 is no

84 is showing first use

Ironically both still showing the knock sensor

 

[69hurstolds]

Ok. But the question is the BLH label. Do Montes use white with black lettering or black with white lettering? THAT was the actual question. Or maybe I didn't ask it correctly.

 

[78Delta88]

Not sure. The threads I found didn't show units with that label.

I just remembered I wanted to ask the question when I saw this low-mile GP engine compartment below. I've seen the BLH on MANY Monte SS cars and Camaros but black and white stickers...which went to which.

Here's that 85 GP with a Chevy engine.

From an 89 Camaro TPI
Superseded number was 16126761, or ACDelco # 216-45.

And then there's this:

And from an 84 Monte SS, apparently all orgininal.

I have no idea.

 

[69hurstolds]

That Corvette site was wrong on the original part number. It is 16022621. They had an extra "2" in there.

 

[78Delta88]

Found three, so not sure if BLH is only Monte

Found 2 for corvette, 1 was BLH..., the other was HKR 382401

Then found one for 91 Firebird, it was ANZR...
