Preventative maintenance

[tucktuck8]

Hi everyone,

I just sold my Subaru WRX and picked up a 2006 4runner sport yesterday with 105k miles in great condition. I've read quite a bit on these forums but decided to join and contribute/ponder/inquire as of recent. From what I've read you all seem a lot more helpful and genuine than the Subaru forums. I'm already in love with my 4runner and want it to last and run smoothly as long as it can. The guy I bought it from showed proof of timing belt change so I know that was done. I was just wondering what I should check and replace for preventative maintenance. I'm going to do oil and filter right away but do you guys recommend anything else? coolant flush, diff oil, break fluid flush, X-REAS check, ect. it runs perfect I just want to help it stay as healthy as it can. Any help is appreciated.

Thanks!

Congrats on your 4Runner purchase and welcome to T4R.org! Yes, you will get all of the advice that you could ever possibly need on your 4Runner. You did not mention which motor your 4Runner has, but I am assuming that it is a 4.7L V8, due to the timing belt change (V6 has a timing chain that doesn't need to be changed out as early as the V8). Presumably, it is not throwing any codes. That being said, yes, check XREAS for leaks as it tends to die around 100k-120K miles. A radiator flush and refill is advisable as well. There seems to be some controversy about tranny oil change here on T4R.org, but I have 105K on my '05 and I am about to have mine changed. If yours is a 4x4 you probably want to have the transfer case fluid changed. I'm sure more peeps will chime in, but that's what I've got off the top of my head at 4:35AM in the morning.

Like all Toyota's of late cleaning the MAF sensor once every year or so is a good idea to keep things running great. You can search to find how to do it fairly easily. Also make sure you exercise your center diff lock and 4lo once a month or so. They have a bad habit of leaking or locking up.

After I had purchased my 4Runner used a while back...I started by taking her to shops to have maintenance/work done. Being a college student and having little knowledge about my 4runner that often meant going to a variety of shops and having the work done that was suggested. Resulting in a cocktail of fluids(sometimes incorrect fluids) and being over charged for services that are easily done yourself. One place charged me for platinum plugs(my v6 calls for the coppers - but I know platinums will work fine) but put in the copper plugs. So they charged me for the more expensive plug in put in the cheaper plugs.

My advice is to just learn everything(often just reading and following the owners manual) you can about your truck so you can decide what is right rather than have a shop/dealer tell you what is right. If you do have a shop do the work make sure you ask them exactly which product they plan on using on your truck and make sure it meets the oem specs.

After realizing I had been a victim of repair shops I decided to do all of my own maintenance and to get a clean start so I knew exactly where my truck stood as far as maintenance. I chose to change the front/rear differential fluids, transfer case fluids, engine oil, cleaned the MAF sensor, did a totally coolant flush(not just drain and fill of the radiator) to ensure that the cocktail of coolant in there was removed. Check the health of your spark plugs and possibly replace them if you aren't positive when they were put in. As preacher35 mentioned there is controversy about the tranny fluid, but I chose to do a drain and fill of the tranny oil pan which would add some fresh fluid.

There are tons of walkthroughs and videos on how to do some of this stuff if you decide to do it yourself and need a bit of help(I know I did).

Congrats on your purchase!

V8 or V6 ? Different stuff should def be done . All fluids trans, rear diff, hope you have the manual it will have most of necessary things , cabin air filter, plugs should be done man I could go on but search & maint sect will help the most .

Do all your fluids change.
