Dirt in intake , how do i clean it out - 1989 Ford F 250

No. It is not absolutely necessary to clean it. But if you want to clean it, just clean out below the air filter. Remove loose leaves and particles of dirt.

The most probable cause is that fuel is not entering engine properly. It may be dirt in fuel filter, or dirt in carb, It runs until the fuel is depleted then quits. God-Bless!

If you're replacing with a stock intake it's a pretty straight forward job...drain coolant, disconnect battery, remove belt, remove alternator and bracket to intake manifold, take note of where each spark plug wire goes, twist plug wires 1/4 turn in each direction then pull up being careful not to tear long rubber boots on wires, leave spark plugs in so no dirt or coolant gets into cylinders.remove e.g.r tube from throttle body,disconnect all vacuum lines and all sensor connectors,you have to be careful removing injector connectors because they become brittle and will break very easily, remove bolts for throttle body and remove body,.relieve fuel pressure from fuel rail by putting on a fuel pressure tester and with a relief valve, there's various ways to release fuel pressure, this is safest, then disconnect fuel line from rail (if you don't want to do it that way you can leave fuel line on and remove 4 8 mm bolts for fuel rail and remove rail and fuel injectors all together, take injectors out from intake not fuel rail by pulling on them from bottom of injectors near intake)remove coolant hoses at back passengers side of intake, remove 2 10 mm bolts for thermostat housing, remove T stat...there may be a bracket on the drivers side rear of intake, (remove top 15 mm bolt, and remove ground cable at back side of head, think it's a 13 mm bolt, then remove 15 mm bolt holding the back of bracket, it's gonna be tight back there but doable with wrench) remove the rest of the 10 mm bolts holding the intake manifold on, remove intake...remove intake gaskets taking care not to let any dirt or debris to get into head ports, I usually put a clean rag in each hole, and clean around them then blow out anything that might have fallen into any ports.you can look rite down into them to make sure everything is clean.make sure all dirt is off head surface and install new gaskets, they lock into place on heads if installed correct. Put on new intake and hand tighten bolts..these bolts have to be torqued in order..starting from the middle of intake torque bolts to 15-22 lb-ft going in a crossover order (right side, left side, right side in an X pattern from center out)...install all connectors and components in reverse order , fill fluids and check over for any leaks or anything loose...I maverick have missed a few small steps but think im pretty close...this isn't a bad job, but take your time and mark anything you think you might not remember where it goes...good luck..any other questions please contact me..

The Fuel Rail is held in place by 3 bolts, Remove the Bolts and then Injector will lift straight up.

WARNING.... BLOW the injectors AREA CLEAN of all the Dirt and stuff that has surrounded the area. This will prevent the dirt from entering the Intake and Cylinders... Here is what an Injector will look like

Clean throttle body and check mass air flo screen for dirt and grease you can clean both with carburator cleaner.the throttle body is the flapper on front of engine intake.And mass air flo is inline on the air intake hose going from air cleaner to engine.It could also be tps sensor but you will have to hook up to computer to tell if this is any kind of sensor problem.good luck

intakes must be free from dirt or dust. check and clean the intake manifold runner.

Hi. This idling problem relates to the Idle Air Control Valve (IAC). Most surely it is clogged with dirt. No need to replace it, jus clean it. To clean it you first find it, unstallit, clean it and next reinstall it. It is located in the throtle body, beneath the air intake hose. The IAC provides alternate ventilation to the engine when rpm's are slow, such as when idling. When the IAC valve is clogged it wont open at the command of the Powertrain Control Module and so the engine stalls. Once you locate, unplug its connector, unscrew it (use a star screwdriver) and take it off the throtlebody neck. Spray it with Electronic Conctact Cleaner (3M brand will do) while moving its movable parts with your hands, you will see much black dirt coming out. Continue doing it until liquid comes out clear. Next, let all liquid drip out and wait until the ramaining liquid inside evaporates. That liquid is quick to evaporate. Next reassemble and you are all done. Your IAC will continue to provide you with many years of use. Ah, make sure that when installing the air intake hose back in place, the rubber ring that nests it on the throttle body is well nested to prevent dust and dirt to get inside in the future. That dirt, sand, fumes and dust if allowed enter the throtle body and also the IAC vent clogging it. So make sure the air intake hose is well sealed and only lets filtered air to get in the throtle body. bye.

I found this out today cause I was gonna clean mine. All you need is to use a mild detergent with warm water thats it. You can also get a bottle of like simple green and spray it on, let it sit for a minute or two and put it in the warm water, do not overflow the water into the filter. After that move it around so the dirt comes off and change the water and do it again but with only water, when there is no more dirt time to let it dry. After that put it on, Good luck with that laterz
