New Member with Tundra Questions

Hello everyone, I just purchased a 2004 Tundra (4.7L SR5 4x4 Access Cab) and I have a few questions about it. The truck has just over 122K on it and I have no knowledge of the timing belt ever being done on it. I just ordered the AISIN kit (with tensioner) and I'm wondering if I need any specialty tools to hold the cams or crankshaft? If so, does someone have a link? I've read that you do and that you don't, so I'm becoming confused. Maybe there is a slight difference in the later 1st gens where you need one?

My next question has to do with the frame. The frame on my pickup is solid and I would like to do what I can to preserve it. I live in Iowa and would like to make it last as long as possible, so what is the best way to keep it solid and strong? Clean it really well and POR-15?

Thanks for the help, and I'll try to get some pictures posted later! I'm new to Toyota pickups and so far I'm really enjoying it, even though I'm parking it until the timing belt is replaced.

 

Welcome aboard!

I finished my timing belt using the same kit on my '04 a few weeks ago. You don't need a special tool to hold the cams on this year, but I highly recommend this tool for holding the crank steady.

Here's a picture of the tool in action I put a 1/2" breaker bar reinforced by pipe on it -

The 05-06 models are VVTI so they might require something for the cams. IDK. But on an '04 you don't need anything to hold the cams, just make sure the timing marks remain in sync.

Good luck! A harmonic balancer puller also comes in handy but it's not too tough to get off in my case. You can maybe rent one at a parts store.

Welcome. Fluid film is the easiest way but you have to do it yearly. POR-15 allows you to do it once and then you’ll need to touch it up every 5 years or so. It’s a huge PIA to work with. You need a tarp, clothes you’re willing to throw away and a need to protect your hands and hair from getting the stuff on because it doesn’t come off.
