international 3800

I just bought a 1999 International 3800 with DT466E/AT545 and I am having a hard time finding out which filters to buy. I am replacing all filters and fluids so I know when they've been last changed/flushed. I don't have access to the bus at the moment, because it's at the mechanic's. The...

We bought this bus in 2012 and it ran until March 2020. Since then, the bus sat as we did not have a need for it after covid. We're ready to move on from this bus; this bus was used to transport students on field trips and has 213,247 miles on it. This bus is missing parts. We have taken a...

I have a 2000 international 3800 bus. Sounded and acted like the transmission was going out. Pulled over sat there for a couple of minutes. Was able to start again...only going 35 mph. Found out my air Compressor went bad and it has been replaced. But it still won't go over 35 mph. Someone said...

4000 miles ago a shop switched my fuel filter due to a sputtering type of power loss while accelerating. It didn’t fix the issue, and after pulling the fuel pre-strainer and cleaning it, it ran great. The issue is starting up again. Please note I’ve additionally replaced much of the fuel system...

So I bought a bus sight unseen from a church with plans to drive it home… 4000 plus miles! Yep I’m a little crazy. Also brought all my kids along. We made it home but I ended up paying triple the cost of the bus as I believe it sat so long that the fuel was gross and ruined most of the fuel...

I got a 2000 international DT466e 7.5 window(28ft), dognose style bus. Air bags in the back, just leaf springs in the front. Despite being fully built out she squats in the front, a good 2-4 inches lower in the front than the rear. Well, this is really messing with living in it. My sink...

I have a 2000 International with a dt466e. When I was changing the oil I noticed a bit of water coming out of drain pan. No oil in coolant I cleaned and resealed the oil cooler, and changed coolant filter. Still water in oil. Took off oil pan and pressure tested coolant system. I made a...

Hey Guys have a 1991 International 3800 with dta 360 motor inside. We bought it from a guy last August when was decently warm out and she had no problem starting up. But ever since it got cold its given us a world of problems. We got the batteries out took on the autozone. Had them charge it up...

I recently bought a 1999 International T444E thats cranks and sounds like it wants to start but won't. The best I've found is possibly the wiring cause they're were rats nests all through the engine bay. I've checked the air filter and the hose attached as far as I could see so I don't believe...

Hi All, Listing a 1993 International 3800 DT466 with MT463 with 130000 miles for sale. Heater and 2 AC units blow air. Not sure what work is needed to get them to spec. Bus has no rust, comes with great condition tires/spare, and all seats removed (by owners prior to us). Asking 5800, in no...

Made a video showing how I added an oil pressure gauge to our 1998 International 3800 skoolie. I was not confident in the factory cluster. I know the risks of the tubing and had this gauge laying around so this mod cost me zero dollars for the piece of mind. https://youtu.be/UpYO5uMmgsw

Hello everyone, I’m currently in the process of replacing a master cylinder for a 1997 International 3800. For the bleeding process, I know usually you want the vehicle off, but the electric motor for the hydraulic brakes was getting HOT when I was bleeding the brakes. I want to avoid burning...

Hi! Would anyone have a wiring diagram for a 2003 International 3800 / Navistar T444E bus? I would ideally like to have the full thing but I especially need the pages for all the rear lights at the moment. Thank you!

Hi Friends, I'm in real need of some interior+ exterior pictures of an International 3800 short handicap bus (1997 if poss) before it's been converted. Any pics that show the seat layout or any of the inside would be so much help. Picture from the back showing driver seat and seats Picture...

Time has come for me to face reality and say goodbye to a project I know I will never finish. Few years ago I bought a big beautiful 1995 Bluebird International 3800 school bus with big dreams of turning it into my home away from home and traveling the country. But a pandemic, a new job, and a...

Hello! I have a gutted 2003 blue bird international (DT466E) for sale. This bus is 38' long, is full size and a dog nose/front engine. The bus was bought at an online auction that covered a school district in AL, then driven home. There have been no additional miles added to the bus beyond that...

I am selling our converted 2000 International 3800 mid-size and a few have asked about the transmission. Is there an online decoder that is reliable/accurate? My VIN is: 1HVBBABN0YH261685 Any tips would be so appreciated. Thanks so much.

Hey everyone! This is my first post so I wanted to provide a little background. Feel free to skip the first part if you are only curious about my problem. Problem description begins after the link. I work for a non-profit called Blue Sky Fund. We are a local non-profit in Richmond, Virginia...

Does anyone know where this is?

Hello! I have a 1998 international 3800 T-444E 7.3L school bus She needs a new thermostat and I’m trying to find the best thermostat to keep her from overheating. What temp rating and which brand is the most efficient? Fan clutch is good. Recently flushed radiator. Thank you!

Good morning, I have a 2004 international 3800, I’m having trouble getting it to go into gear. My air pressure builds to 120 psi, but when I select drive, reverse, or select gears individually it stays in neutral. The selector panel for the tranny doesn’t blink when I select drive or reverse...

I'm not to the point of the deck yet I want to finish the cab exterior and most the interior first. But I cant find a good answer to a good way to do the flatbed on this. Focusing on just the deck top nothing else right now so i can plan it out. The deck is rough cut right now too just so I got...
