1992-1997 OBS Ford Truck 5.8L Air Pump Smog Pump Delete F-150, F-250, F-350

[@nuclearcasserole]

I have a 96 ford f 250, been fixing it as things break, it has about 400 thousand miles on it, and pretty much regularly, something breaks or needs repair about every week. The other day, the smog pump seized up, it was a 15 dollar part at the junkyard. I have no idea how long ago the pump stopped working, but the genuine difference in the performance of the truck was instantly recognizable. The engine idle is smooth and balanced, the acceleration is surprisingly responsive and the gas mileage has improved tremendously. Up until the past week or so that I fixed the air pump by replacing it, the truck was something of a real problem to drive, it felt like the truck was always struggling to go up a hill. It is a work truck that works for a living, and often it is driven at just above an idle, about 25 miles or so. usually it takes about two hours, once the pump was replaced and operating, did the whole route pattern in less than 90 minutes. In the mid 90's Ford was still trying to figure out fuel injection, while your video suggests altering the system, I have always tried to rebuild the operating systems to its original function of design. I have owned this truck about 14 years, and with a whole list of new parts and improvements on the vehicle, I am going to keep it as close to original as possible. The trucks now are plastic and not built for work, the old timer vehicles were made for working, and around my house, if the truck doesn't work, nobody gets to eat.

[@QuickSpeedShop]

I'm going to guess by what you described that the pump was seizing up for a while and dragging the engine down with it. When it finally locked up and you replaced it with a junkyard piece that turned freely the engine was able to operate at normal load again.

[@nuclearcasserole]

@@QuickSpeedShop I have no idea how long it was out, at 400 thousand miles, there are funny noises from everywhere, I put in a double roller timing chain, and it has all its horsepower, almost 25 years later. It started grinding, then stopped overnight.

[@mongomay1]

I was wondering how to verify that the smog air pump is actually working before replacing or removing it. Thanks for any feed back. If you have exhaust noises get a bright flashlight and look at your manifolds for cracks, both of mine have broken. I would make sure using a good exhaust gaskets, checking the flatness of the replacement manifolds and re-torqueing after a couple heat cycles by loosening then torqueing again. Maybe use brass nuts to secure the manifolds.

[@realazliving]

Do you know this pulley is completely unnecessary? Just take off the pump and buy a belt a few inches shorter. Cheaper than this and you get a new belt in case yours is worn. I forget the exact length but you don’t need that pulley. This also increases the contact area of the belt to pulleys. All that idler pulley you added does is make it easier for the belt to slip.

That Proform bracket is NLA as well. Had to go to AmericanMuscle and order the real Ford smog pump eliminator kit 50271 for $99.99.

[@jacksmith2315]

Wouldnt it be cheaper and easier to just remove the pump and everything and get a smaller belt?

[@QuickSpeedShop]

In theory yes, if you want to figure out the right length belt. Then you need to remember which one fits if it breaks later on. I did it this way because it mimics the OEM way and uses the original belt.

[@Plwalkr]

That's what I did. works fine. I suppose you would just write the size down.

[@ColinQuinnuniverse]

Get the shorter belt and the replacement part is × # of ribs in × length in millimeters. Just right it down under the hood or in the owners manual. Easy peasy.

Where can I get the correct size manifold plugs I need to complete this job? I don't have a way to weld the ends as you had suggested, so I'd like to find the correct plugs that would work instead. Could you possibly put a link in the description, or list the part number I would need to do that part? I appreciate the help Sir. Great video. Thank you.

[@QuickSpeedShop]

I looked on the internet and am having a hard time finding the blank off plugs listed separately. You can get the EGR tube connector fitting which will have the correct thread on the non nippled end. You could get two of those and have someone weld the nippled ends up for you. Dorman makes them, their under $15 each. Just search 5.8L EGR tube connector. If you could find out the NPT thread size of the connector you could probably find a black plug with same thread to plug rear manifold holes.

[@groovinav]

@@QuickSpeedShop Ok cool. I'll check it out. Question though. Is it the same principle, except for the parts removal, if I simply connect the incoming and outgoing hoses together, right at the smog pump location? Would that work, just to get me back on the road for now? The one on my 1997 f250 5.8 HD has seized up. At least it didn't leave me stranded though. I've owned this truck since new and has never let me down. Coming up on 300K miles and I want to make it over the mark. Thanks again for your help. This has helped me out, and I ordered the part numbers you provided in this video. I just need to figure out an easy way to do the tubing bypass, so that my truck will run again. Thank you for your help Sir.

[@QuickSpeedShop]

@@groovinav Actually that should work. If you leave those check valves in the lines in place it won't backfeed and you could just hook the lines together with some hose. I don't see why that wouldn't work.

[@groovinav]

@@QuickSpeedShop Great. That's quick and easy to do. After connecting it this way, if the check valves are bad or ever go bad, will that cause a CEL to come on? I read a Tech note on the smog pumps, that said bad check valves can be the cause of seizures due to back flowing gases and such. Just making sure this would be safe for a permanant fix.?

[@QuickSpeedShop]

@@groovinav The CEL shouldn't come on as long as the diverter valve is still hooked to vacuum. With the lines hooked together even if a check was bad it will just pass exhaust from one manifold to the other which won't hurt anything.

[@jjensenfarms]

I just got the same setup and replaced the pulley on the new bracket with the Dorman 419644 and I noticed that that idler pulley is just a hair smaller than the factory Air Pump pulley. I am assuming that the belt tensioner makes up for the difference. Did you notice that? Thanks for the information!!!

[@QuickSpeedShop]

I didn't notice the size difference, but the tensioner does take it up.

[@saltcreekammo]

Where do we find the plugs for the manifold? I'm not sure what exactly you're talking about... Am I plugging the tube or the hole in the manifold (or headers) itself?

[@QuickSpeedShop]

It's best to plug the hole in the manifold with a plug. I replaced the passenger side manifold (due to a crack) with a Dorman aftermarket manifold and it came with a plug. Most of the after market manifolds supply both open bungs and plugs with their manifolds to fit engines with air injection or without. On the driver's side I had to cut off the tube at the bung and weld up the bung to close the hole, essentially making it a plug. I don't exactly know what the thread pitch and size of the plug needed is or I would have listed a source to get one. You might have to get a hold of Dorman and see if they will sell you two plugs separately.

[@metal.mover23]

Can't get that bracket though...I ordered that proform 68110 and it's a different bracket then in this video

What if you just loop the Air Pump like you did with the valves? Or run it straight to the solenoids. I have a exhaust leak somewhere, guessing its either the manifolds or the egr piping in the back

[@QuickSpeedShop]

The problem is that the air pumps will seize up and throw the belt, that's the main reason I remove them. Sounds like you could either have a cracked manifold, which is common, or a smog tube that is leaking, although I think the newer ones are made of stainless so that don't usually rust off.

Was it the exact same size as your smog pump?

[@QuickSpeedShop]

I didn't measure the pulleys so those diameters don't mean anything to me. On both trucks I have done, a 1995 and 1997, I used the pulleys in the video with the factory serpentine belt and it worked fine. Both trucks had original Ford smog pumps with the same size pulley. Both trucks were 5.8L. The 5.0L has a different belt length and different pulley size. If you are trying to do this on a 5.0L all you need to do is put in the smog delete bracket.

I can’t find any other information on You Tube to see what to check next. The 4wd and 4wd lo lights light up on the dash when I shift the transfer case. My truck doesn’t have any type of button or dial for 4wd. Just the floor shifter. You seem fairly knowledgeable with these trucks so I thought I would ask you for some advice.

[@QuickSpeedShop]

The transfer case shift in and out manually with your truck with the lever. Since the lights are lighting up it should indicate that the shifter linkage is working and the TC is going into 4WD. I would bet that the auto hubs are not engaging. I would remove the caps on the ends of the axle and grease the components and see if they are bound up. Another option would be to find a set of manual hubs at the junkyard and swap them onto your truck so you will be able to engage the hubs by hand.

[@jeffedmondson7861]

QuickSpeedShop I pulled the hubs off and completely took them apart, cleaned and greased them following another you tube post. I could be wrong but they seemed to be moving according to the video. But if the light means the transfer case is working properly and there isn’t anything else in between the transfer case and the hubs that could cause it not to work it would have to be the hubs.

[@QuickSpeedShop]

Could be a bad coil, distributor pickup, fuel pump issue or relay, computer issue, fuel pressure regulator...Without actually being there I can't diagnose it. Find someone with an old scanner and have them read the codes thru the plug on the inside of the left fender.

What change does this have on the truck? Why do it?

[@QuickSpeedShop]

If you read thru the comments you see I answered this several times. In a nut shell, removes access parts that fail on these old trucks and leave you stranded. Deletes obsolete technology that does little if any emissions reduction. Just showing how it can be done like Ford did it on the factory exempt trucks. I'm not debating on the "why" anymore. If you chose to do it here is how its done.

[@markduble5101]

@@QuickSpeedShop Thanks! I was honestly asking why because I wasn't sure if it was a performance thing. I get replacing multiple older parts with one new part. I stumbled on your video trying to find out if my melted diverter valve was actually needed.

[@non-affiliate-marketing]

This video has been so helpful, I appreciate you taking the time to make it. Some part is confusing to me though, I think the 97 f250hd 351w has a different air pump setup. Your pump feeds into the front of the passenger manifold. My truck has only the egr solenoid with pipe going straight to the same point. The driver’s side manifold has a large port in rear that wraps behind the engine and leads to the pump. All the videos I have watched have the driver side manifold without an extra bung. I have been stumped on finding the records or diagrams of the different smog/egr iterations for the truck. My truck seems to be an outlier. I did find that the 1987-95 shorties are different than the 96 shorties from Holley so maybe that is a clue. Any help would be appreciated!

[@QuickSpeedShop]

I have done this '95 and a '97 and they were both identical. Only the EGR goes into the front of the pass manifold. If you look closely at the parts on the table you can see the EGR tube. The air pump is hooked to the black sheet metal tube with the hoses on it that bolts to the engine. The pipes are laying over each other making it look like the air pump goes to the front of the manifold which it does not. The driver's side only has the rear port which I cut off and welded up. I replaced the pass manifold because it was broken and it came with a plug for the rear air tube.

[@non-affiliate-marketing]

Will this work on a 5.0?

[@QuickSpeedShop]

The process should be the same for the manifolds and the air pipes. As far as the air pump idler and pulley I don't know. I know that a 5.0L and 5.8L have different belt lengths. The stock pulley on the new idler might work on the 5.0L, but have never tried one. I also believe that the belt routing maybe different, but don't know for sure. I have only done this on the 5.8L trucks.

[@edwardmissouri2216]

Okay, this is not totally related to this change, but I have a 89 f150 with the 4.9 inline 6. It is fuel injected. The smog pump is not long for this world. there is a fan above it on the wheel well that runs after I shut the engine off on lot days. I don't know what it cools, but if I delete the smog pump, will that cooling fan still do it's job? Thanks.

[@QuickSpeedShop]

I'm not sure what the fan would be for, but it shouldn't have anything to do with the smog pump.

Greetings! I have both a 95 F150 4.9L 300cui 93 f150 5.0 302 cui I am planning on doing a smog delete on both in steps.. Currently on my 93 5.0L with a locked smog pump. Like to remove the smog pump but leave the egr. My 95 4.9L has a broken exhaust system and I'm considered removing the smog system. I was so confused on all the different hosing and lines but watching you video has giving me some relief and hope that I can do this. I plan to block the egr off. Remove the air pump and run a bypass. Either by doing what you did by a idle dummy bracket with the original belt or run a smaller belt. And on the My question is . Would this somewhat work on my 5.0l and 4.9l? And the air emissions unit. It has 3lines to it right? Intake exhaust and air pump. Do you take the intake and exhaust ends the loop those together?

[@QuickSpeedShop]

First of all this is for the smog pump only and not EGR. They are two different systems that act independent of each other. As for the 4.9L, don't know, never worked on one. As for the 5.0L, all you should have to do is buy the bracket and bolt it on as it is actually for a 5.0L to begin with. Read video description as the original part number in video is not in production anymore. Also far as I know the 5.0L is set up different with the smog tubes bolted to the back of the heads and not the manifolds like on the 5.8L. I just did a 5.0L and all I did was remove the smog pump, plug the hose to it and, bolt on the bracket. I left all the tubing and and vacuum lines in place.

And I actually got a K&N air filter for $2.00 at salvage yard. And I got the fresh air intake from a 300 inline 6 truck that goes from behind the grill to air filter box. I really can't tell you how much better this old 1988 f250 runs and I'm getting between 18 and 20 mpg , give or take a little. Was thinking about adding an electric cooling fan and removing the mechanical one to free up a little more power. . One last thing. Down on the frame where the fuel filter and abs pump are.
