2007 Tundra Known Problems

I am looking at buying a 2007 Toyota Tundra it’s only at 80,000 miles. The engine is a 4.7L V8 DOHC VVT-i 32V. The guy is letting the truck go at a pretty good price. I am just wondering if there are any known problems for this truck I should be aware of. If there is major maintenance needed at 100K. Thank you.

 

Check the timing belt replacement history, make sure the frame isn't rotted.

 

4.7l engine is an amazing engine..do the normal timing belt, ensure the rubber/plastic components are taken care with regular 5k FullSyn Oil changes and you will see this engine run forever.
You may need to do some modes like replacing the plastic heater T's on the engine as well.

In regards to the truck body.. as mentioned take some under carriage pics of the truck and post those on here and we can guide you on how bad is the rust on the truck. Although I am sure you may have enough knowledge on rusted cars to not need our opinion..

Lastly check the AC/Heater by switching the AC vent switch to each Vent position and verify it works properly.. the 2nd gens have a notorious issue with AC servos vents getting stuck which is a BIG big PITA to fix. I.e. needs the removal of the whole dash.. Its the only major issue thats on my truck.. and I have been putting off fixing it for the time it takes to fix it.

 

I have a 2007 4.7L DC it has been solid I would suggest replacing the timing belt every 100k miles, at the same time I do the water pump and a new serpentine belt ( you have to take it off so might as well put a new one back on

the only major part I had to replace was the alternator @220k miles, still have the original starter and radiator

The SAIS system has been a thorn in my side failed the first time @ 135k miles, had the system ( 2 air pumps and 2 switching valves) replaced under warranty than failed a 2nd time @ 250k miles which at that time I bypassed using a Hewitt Gen 2 kit, my truck now has 265k miles

The air blend door that switches between vent and defrost broke on me the part has 2 servo motors with plastic gears and axles to fix the problem it is a $1800 job at the dealer they will take off the dash to access but there are a few YouTube videos where you can go through the bottom of the dash just above the gas pedal it is about a 6 hour job


80k miles on a 4.7L is just getting broken in

 

Maybe look out for the secondary air injection pump haveing been replaced or not. They pretty much all fail on the 2nd gens and they aren’t cheap to replace. Bypass kits are better price wise.
