So the closest DIY for a timing belt has been the Toyota tundra 4.7. Is there any gx470 write up? Do you guys leave the front bumper on or pull it off? I am very very seriously considering doing a DIY while doing my wife's timing belt!

If you did a write up with pics, they would write songs about you for the next hundred years.

I don't mind taking pictures but I'm not excited about having to type up the word for word thread. Maybe I can take pics and write scratch notes and someone else on here can help with the post. I'll chat on the phone and we can team up. I am doing the timing belt 100% this weekend. I will be replacing both belts, water pump, all necessary gaskets and seals, both right and left bearings/pulleys. Prob doing plugs as well.

well sometimes a pic will tell a thousand word so just post them in the order of operation and we can figure it out... please do, thanx

An FYI for those bold enough to tackle the 4.7 belt:

Incorrectly setting the belt at TDC versus the "T" on the cam gears can result in the cams spinning, bending valves. This is not a hard job, but not for the weekend warrior.

That said, the 4.7 is the same on all cars once you get into it a bit, so any 4.7 DIY should do you. You will need to pull the radiator to do it on the GX.

well shoot if you have to remove radiator then might as well replace mine with a koyado radiator while i am at it, but i think i will take my gx470 to a toyota dealer near me to do it all and avoid the hassle - but mine is an 04 with 50k miles so does anyone think it's too early?

Way to early, 90,0000 and I am sure toyota picks that mileage with plenty of leeway.

clubsport

cool... i am always itchin to get things done but yeah i might leave that alone for awhile then

You must have other toys or stuff to do around the house to keep you busy for the next 40,000miles LOL.

I've seen 4.7s with 220k on the original belt.

You're alright.

Sometimes a person can read too many posts and start to hear foot steps. Every time I read that trnasfer case o-ring leak, I want to run out to my car and look, but I don't.

Perform regular maintenance as specified and have fun driving it. I always look on the garage floor for any kind of fluids. If your radiator is acutally leaking, you can smell it in the front of the car, after you stop and walk around the front.

There is one exception to the fluid on the garage floor rule. After an oil change by the dealer or other, you will get drips on the floor, from some getting spilled on the skid plate. I just spread out about 6 pieces of newspaper stacked on each other, under the engine for a day or two.

The only time I didn't getting any dripping is when I removed the skid plate completely, changed the oil my self. Pain in the butt. I have paid extra, to have my skid plate removed, some places don't charge. If you have an older GX with rusted bolts, then they will brake. This opens another can of worms and more foot steps.

I rarely listen to my GX at start up. All sorts of sounds, that really don't mean a thing. The plastic panels that cover the engine will rattle sometimes at start up. I usually wait a minute or two (first start up on cold days), for it to come down off fast idle, then I listen. Purrs like a kitten.

yeah i used to spend lotta time working on the g35 coupe to make time fly by but now it's cold out so i just conjuring ideas for the gx470 this summer when it gets warm hahaha

well i have rusting undercarriage so i wonder if i can do oil change without touching it - anyone?

cdew002

Without touching what? The undercarriage? Sure, but you're probably going to have to remove the skid plate to get to the oil filter - if it's rusted like mine, just be sure not to over tighten the skid plate bolts when you put it back on.

Coat those under carriage bolts with grease next time you work on them
