I REQUIRE A VACUUM PIPE DIAGRAM FOR A 2004 l200 MITSUBISHI PICKUP

It is in the main fuse box under the hood, (Black box next to the battery). It is relay 6. A small, black, square block that should pull out. It will be a tight fit so it might come out suddenly. Try this website for a diagram of the fuse box.

Search "wiring diagram Mitsubishi L200 turbo"

You may have a shorted light in one of the tail or turn signal assemblies. You can get a wiring diagram, but you will still start there; testing all four corners, all lights and wires behind the plugs, and you will find the culprit. If you have a tow package, try disconnecting the trailer plug. Those go bad and you will spend days tracing nothing !

look inside the socket coin fall into the socket

We do not have this model inthe USA.

Check for

vacuum leaks on intake manifold,

the air tube between the air filter.

intake manifold vacuum hose.

===
clean throttle plate with Berryman carburator cleaner

SEE sample picture HERE
===

Also remove carbon built up behind the EGR valve and the EGR passage tube.

===

Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.

More un-metered air (leaks) will lean out the fuel mixture.

Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.

At idle,just spray and listen for the RPM surge.

The in-rush of carb clearer will increase the RPM on the motor.

Record the problem spot(s) and address it later.

===

EGR carbon built up require 2+ hours to clean from start to finish.

You will need a new EGR base gasket before your start.

Locate and remove the EGR valve after the vehicle is cool down.

Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.

Remove the EGR valve.

Inspect the location of the carbon built-up inside the valve and the EGR passage tube.

SOAK these areas with WD-40 spary.

You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.

RE-SOAK the carbon and let it sit for over-night will also help.

One the last round,pass a shop vacuum of the EGR valve and the passage pipe.

Install the new EGR gasket and connectors.

Allow the vehicle to warm up outdoor to burn up any remaining WD-40.


Take it for a test drive.

hi i have a l200 4work pickup and the summp gasket is leaking but u can just drop the sump from the bottom is there a seal i can use

Sounds like a failed bearing or bad syncronizers. Will require trans disassembly to determine failure.
