Question about 1993 Dodge Caravan

Open Question

Air breather hose connection configuration

3.0 L FI doing a tuneup and noticed 2 ports for hose connections on the air filter box that a previous mechanic had simply connected together with one hose. The rear valve cover for cyls 1,3,5 has a port with a hose connected to nothing, so it shows a lot of dirt inside. It would seem that the valve cover (breather) hose should be connected to either the upper or lower port on the air fliter box. Question is which one and where does the other port terminate? I'm guessing that one hose must terminate to the air since I have not located any available port.

I do not have the solution for you but I will make a suggestion if you do not get an answer from someone else. Find a 2000 Dodge Caravan like yours at a used car lot and pop the hood and take a look. That may be your quickest solution.

SOURCE: I removed the air resonator

Hello and welcome to FixYa!
The other hose you are referring to may not be connected to anything for it serves as a breather. But do check the throttle body pipe if it's open. If it is then there it should be.
Hope this helps and thank you for using FixYa! Have a good one!

How do i change the airfilter on a 95 murcury villager

The air filter is not quickly changed. I found it best to disconnect and remove the battery first. Then the housing to the air filter is more easily accessed. The air filter housing is that big ugly black plastic box sitting on an angle behind the battery. Loosen the two hose clamps on the downstream side, un-clip the wired sensor on the housing, and remove the 3 bolts that hold the box to the car body (one high, 2 low) Pop off the air-in port and pull the air-filter box from the car. See how it\'s wire clamped on 3 sides and use pliers to lift them off their stays. Open and remove old filter, wipe or blow out any debris and gunk found in the housing, put in new filter. Carefully re-clamp shut, being sure it\'s seated correctly. Lightly clean and grease the ports that will be re-clamped and put it all back. Yeah, it\'s tedious, but now you know how it all fits together. And you can clean all that acid on your battery, battery posts and tray before putting that back in while you\'re at it, making for a better connection there too.

2002 ford ranger gas issues

Okay I got tired of this and did something about it . so here is the solution . Pull off the bed . 6 bolts , hit them with a 2 pound sledge hammer and use a impact or a big 1/2 drive . Disconnect tail light harness on drivers side just above bumper area. undo screws on gas tank filler . two people can lift off bed . on top of the spare tire you will see the charcoal canister . About a foot long and black with a solenoid on the drivers side .connected to this solenoid by a cigar sized hose is a black box with another hose on the other side . This is a air filter . Lets in air when the solenoid opens so the fumes can travel back up the line . Notice that the open end hose is just right for collecting all the dirt and water that flies up there . This canister as it is marked has some foam inside like a lawn mower air filter . either go buy another at the dealer or simply tap it on the truck frame and get all the dirt out and blow out with air hose would be good if it is wet inside . Blow in it to make sure air flows freely through it . Put it back on .

Okay if that just happens to not be it here is how you find out what is it . After removing the bed make sure the vents on top of the gas tank are not plugged by blowing and sucking on them . Then unhook the fume line from the solenoid on the charcoal canister . Drive , I know no lights for breaks , to gas station and start filling up . If it splashes out then it is on the tank side . If not then plug up the line you removed and fill. If it splashes out then it is after the solenoid . Put thumb over other end of solenoid where the air filter is attached after removing the filter hose of course . If it splashes out then it is the air filter .
Make sure you point that hose on the end of the air filter at a downward angle so it does not collect water and dirt again . Stupid Ford makers .

Process of elimination.

I am so glad I can now fill my tank . Why in the he## can not all these mechanics on all these forums come up with the answer ? Or even the dealership.

Air filter replacement. A plastic box attached to the inside front is marked as having an air filter. The plastic box, when unscrewed and w/two lg. hoses disconnected, appears sealed w/no way to open it....

The previous owner is an idiot. The air filter may be BELOW the box you are refering to. That hose is the crankcase vent and if thats not connected the engine will pull dirt in through that hose. The box has clips to secure the 2 halves of the box. get a new hose. I would not have bought the van if I saw that hose missing.

How do you change air filter on 99 ply voy. 3.0 engine

The filter is located down low under the air box which connects to the throttle body. You'll need to remove the fresh air inlet line from the throttle body (loosen hose clamp) there are two (2) large phillips head screws which hold the air box in place , remove these there may too be a clamp which connects the air bos to the filter box, if there loosen and slide away the air box. On the filter box there are two (2) clamps that hold the filter in, snap back these claps to access the filter and replace. To install reverse the above.

I hope this may have assisted you,

Code P0410- Secondary Air Injection Malfunction

The air injection reaction system (AIR) is on all 2004+ 4.2's. There is an electric blower under the truck, tucked inside the frame rail about under the drivers seat. The blower draws it's clean air from a hose tied into the air inlet tube between the airfilter box and Throttle body, pressurizes it slightly and blows this clean air into a port in the cylinder head directly above the exhaust manifold, dead center. There is a can shaped check valve bolted to this port with the air hose clamped to it and an electrical connection. The most common failure point of this system is this check valve. Remove the hose, the electrical connection and 2 bolts and it's off. Very easy. Problem is, it's about a $125 dealer only item.:banghead: The check valve gets corroded/cruded up and doesnt seat. Let it go long enough and moisture from the exhaust can back flow into the system and destroy the $$$ electric air blower. I'd start by removing and checking the valve and check the hoses for water.
Inspect the air pump and wire harness under the Trailblazer's frame rail, since you did mentioned that your had your transmission serviced and they would have had to work under there to remove the transmission pan to replace the transmission fluid and filter. There are 2 fuses you need to check also. AIR fuse 60amp....AIR solenoid fuse 15amp.
Good luck and thank you for using Fixya

My 2003 subaru forester idle very rough. if you open the hood and look at the engine it is shaking like its firing on only three cylinders. I need some help.I changed the spark plugs, gas filter, air...

1) Check all the vacuum hoses for a leak in the rubber hose or a hose that isn't connected. Vacuum leaks cause motors to shake and stumble on acceleration.
2) There's a plastic T connection on the back side of the engine behind and under the air cleaner box. That T connector joins together three air hoses of different sizes and is prone to breaking from heat stress. Only a Subaru dealer will have this part.
3) Even though the spark plug wires are new, you may have a bad one. Don't waste your money on cheap parts; they cost more in the long run.
Good luck!
