The smog pump on the Mark VI finally locked up tonight and broke the belt. Good riddance I say, it will be going away in the near future. My question is can I run a shorter belt and run the A/C or do I need a bypass pulley of some sort in place of the smog pump? Also where is the tensioner for that belt? If it's like the one on my '88 Grand Marquis was I feel like there was a bolt to loosen the tensioner pulley and another to adjust it? Maybe I'm thinking of something else. Also if anyone knows the length of belt I'd need to bypass the smog pump it would be greatly appreciated.

Shorter belt and just run the bottom length of the belt over the tensioner pulley. Don't remember of the top of my head which length belt is the one to use though. It's listed in plenty of the smog delete threads though.

from my search, it looks like k060565 (56.5 inch). Wait for confirmation though.

I used a 56,1" belt after the smog pump delete, I run the belt underneath the tensioner pulley.
It could've been a slight bit longer, was kinda hard to get it on over the edge of the pulley with the tensioner completely loosened.
For tightening the tensioner has a slotted bolt on the backside of the bracket, loosen that and the pivot point bolt on the front side, normal 3/4" square drive hole on the tensioner to tension it and tighten bolts.
Running the belt over the tensioner might be smarter for less belt bouncing, but I have it underneath the tensioner, since that's not putting weird stress on the tensioner. Dunno how, but I did somehow manage to bend the previous tensioner.

Yeah, I ran it over because after the smog delete, having the belt running by that gaping hole just looked weird to me. If you are leaving the smog pump in place for a while, I think over is also better for clearances. It might clear, but I don't remember.

Thanks for all the info. The car is going in the garage for the winter next week. I’ll probably make the smog delete a project for a nice day that I’m off work.Comment

Well I got the belt on on my lunch break 56-7/8" was the closest belt I could find in stock. I ended up running it under the tensioner, so far so good. I'm probably going to see how far I can get on deleting the pump itself after work tonight.Comment

Smog delete complete, easier then I expected. I even put nice new bolts in the MAP sensor bracket.Comment

Nice! Glad to hear it was an easy process.

@mercurygm88
Did you remove the smog pump before installing the belt? For me, running the belt under the tensioner would mean the belt would hopelessly run into the body of the smog pump.
@Derek
Can't you see the pic I attached in my previous post?Comment

Yah, I guess his would be a different version of the same thing, eh? Your post says you ran your belt under the tensioner too, looks that way as well. Anyone run it over the tensioner?
In any event, I'm excited to tidy up the engine bay some.1985 LTD Crown Victoria - SOLD

I'll post a couple when I get the chance. I pulled the pulley off at work with an electric ratchet and installed the belt. Then I removed the pump, hoses, and solenoids when I got home. I don't know if the smog setup on SEFI cars is different but I feel like everything on the drivers fender of my '88 looked totally different. The smog pump on the '88 was slightly different as well it had vacuum hose running to the cruise control servo. The one on the Mark VI just had the 3/4" hose running up to the solenoids and check valves on the fender.Originally posted by DerekTheGreat View Post
Also i know it's not correct and "unprofessional" but I also removed the plugs going to the two fender solenoids and the EEC III test port plug. I have no use for them and they just looked bad, so I cut them out and taped everything up. The only thing there now is the MAP sensor which I may relocate to clean the area up even more.Comment

On mine half of the belt was rubbing the front edge of the smog pump pulley, so I grabbed an electric ratchet and removed the pulley.Originally posted by Arquemann View PostComment

yeah the pulley is pretty much in the path, but 3 bolts gets that out of your way. Same problem on Fox cars if you ever have to do it on one of those, but same fix.86 Lincoln Town Car (Galactica).
