Hi

Just as a little bit of personal research, I'm looking for factory workshop manual descriptions of how to clean an air filter out during a vehicle service. Toyota workshop manuals would be brilliant to use, as I do work on a reasonable number of *j120r prado's, zze122r corollas, and lots of **v36 and **v40 camry's.

 

I would also like any decriptions of how to change the brake fluid as part of a service, the correct procedure out of factory workshop manuals would also be good. Both the prado setups would be good, the pressurised nitrogen booster as well as the traditional vacuum booster.

 

I know this is very very basic, but I'm just trying to find some solid definite factory instructions to prove a point.

 

My first year tafe booklet does state that to change brake fluid, I need to replace the fluid in the reservoir, and then drain fluid through each wheel cylinder until NEW brake fluid appears. I can't however find a reference to cleaning air filters correctly, It was probably assumed to be basic knowledge.....

usually when you need to 'CLEAN' a factory air filter (whether it be for the engine or cabin), it's time to REPLACE it

:P

I've got a K engine manual. It says that an air filter should be "cleaned" every 5,000km by spraying with pressurised

air just to get any crap out of it. However it doesn't mean it needs replacing. The filter was said to be replaced every

15,000km if I remember correctly..

that is the general gist of it. every service, (or more frequently if under severe operating conditions) it should be "cleaned" with compressed air, I'd like to emphasise that part, the compressed air, and it should be replaced at a set interval determined by the manufacturer, or more frequently in severe operating conditions.

 

I want to find this in workshop manuals specifically, to prove a point though!! The point being that taking a filter out, banging it on the ground a few times to dislodge some of the crap in it and reinstalling is a bodgy half-arsed way of doing a job, and the customer is really not getting what they are paying for.

And you blow it out with compressed air from the inside out.

 

Not too close though, or you will tear the element.

with the only exception being a viscous paper type (think the subaru genuine equivalent of an a360, or maybe a nissan genuine part as well) which you aren't supposed to clean, when they get dirty you just replace them..... I've always cleaned them with compressed air as well, after about 30-40k km despite having no muck coming out when you clean them they block up bad enough to cause carby cars not to idle and all sorts of stuff...... I try to avoid viscous paper type elements.....

 

I have to say I'm not a fan of the "non-disposable" type k&n filters either, they don't get cleaned out regularly and don't seem to be as good as a clean oem type filter.
