2010 Toyota 4.6 V-8 Interview Part 2


we’re back here at toyota motor sales USA to get more information about toyota’s new 4.6 all aluminum v8 i’m mark williams with pickup trucks calm and with me is our resident expert David Lee right here David let’s go in deep this engine start start talking to me from the bottom up what what’s new about this engine sounds great Marquis others a lot of changes here we’ll be able to see it but if you look down in here to the engine block the 4.7 liter v8 which supports dates back to nineteen ninety-eight had a cast-iron block without always cylinder heads and a timing belt for valve control now and then we mention here we’re now going to an alloy block as we do with our big 5.7 liter v8 that saves us a lot of weight on the engine the other thing we’ve done is along with other newer engines as we switch to a timing chain for our cam drive system which gives us improve reliability consumer that buys the 4.6 liter engine now he’s not gonna have to worry about the occasional timing belt replacements through the service life of the engine so there’s some reduction and maintenance right there you mentioned the aluminum block obviously that’s going to save some weight is there a physical size difference between the 47 and 46 here is this smaller just because it’s a smaller this engine actually the block it should be very close to the same size it’s the same bored I ammeter as the 47 in fact for you trivia buffs out there every year engine for the tundra whether it’s the 4.0 liter v6 the 47 46 or the new 57 all of them have a 94 millimeter board but anyway that aside before points6 is the same bore as the 47 but actually has a little bit shorter stroke in the engine so but block size should be very similar as we move up in the engine you’ll see that there are some physical changes so similar size less weight another benefit is aluminum block of course it comes up to operating temple quicker you know for faster warmups in the morning on cold starts and the early part of the drive that interesting the main pieces of technology that are brand new or different about before six competitive forces the valve train of the engine here we have a dual independent variable valve timing on this engine just like we do on the 5.7 liter where the 4.7 just had a single variable valve timing with intelligence system operated only the intake valve timing could phase that in advance and retired that now we can do that on both camshafts like we do with the big v8 so what we gain here are some performance and output benefits reduction in emissions and also an improvement in fuel economy output for its size is great so 310 horse 327 pound-feet of torque on the valvetrain that i should point out it’s the same it’s on the 57 and that is your 4.7 liter engine folks the valve adjustment was done with it had solid lifter set up on it you know a human bucket set up so about every 60,000 miles we recommend that they were going to the dealership and have the clearances checked and inspected by the dealer this engine like the big 57 uses roller rockers and hydraulic valve lash adjusters in there so there are no maintenance requirements on that so as long as the engine is running properly and has been serviced the custom consumer no longer has to worry about those valve adjustments either so we’ve taken off the engine cover the most pronounced thing that sticks out to right off the bat as is gr yes that is a system that’s unique to this engine right now for the tundra pickup this is a cool EGR system traditionally EGR Tsar that system is known for emissions reduction to reduce your nox emissions on it Kool the combustion temperatures inside the engine the other side benefit that I see is that on the light engine loads if you don’t have this system you’ve got engine displacement there that you can’t vary so if you’re going to draw air in there and run your engine you’ve got to put it up gasoline in that cylinder to ignited haven’t burned a proper mixture to still have a clean engine so this allows us under light engine loads to introduce a little bit of exhaust gas in there and actually reduce the amount of volume ever putting in which allows us to them further reduce the amount of fuel we’re introducing help enhance your fuel economy when you you know like like cruising posting conditions they thank you very much for sharing all this information it looks like it’s going to be pretty impressive to the tundra lineup that’s my pleasure market thank you for more information about 4.6 liter v8 in the toyota tundra and sequoia for 2010 go to pick up trucks com

  1. all you tundra lovers are morons. as I said on the first video, I work as a TECH for toyota, and I was a FORD tech for 4 years before that. I would take an F-150 any day over a new tundra. everything about it is better, its more reliable, better gas mileage with the 5.4 3 valve, better payload, better towing, and its much better looking both inside and out. the tundra is so fucking ugly it makes me sick. I work with 64 other techs, and every single one of them HATES them

  2. If you are so proud of Ford what are you doing working for Toyota. You wish you were a TECH…gogogo tundra

  3. I wish I was a tech? that makes no sense, I am a tech, and probly the only one here thats A.S.E. master certified at age 20. I work for toyota cuz they offered me MORE MONEY you fucking tool. technicians dont work for just the car companies they love. believe it or not, out of the 45 techs at my shop, I can count on 1 hand how many actually like yotas. they suck, I see them everyday, I fix them, YOU dont. if ur gonna try an outsmart a guy that fixes them for a living, ur a fucking idiot.

  4. and that isnt counting the 15 or so body shop techs that work in the shop next to me, they REALLY hate toyotas, cuz everything they consist of is extrememly cheesy, low quality material and it breaks easy. I dred interior work, the interiors oy yotas are so flimsy and brittlr that just taking a radio out is a nightmare in the making. doesnt matter how skilled you r, ur gonna break, scratch, or chip something almost everytime. I'm american, thru and thru, I will never b caught dead in a yota

  5. I bought a toyota becouse i wanted a truck made in america, by americans. If i wanted a less reliable, ugly slower truck thats made in mexico, i whould have bought a ford.

  6. the big three? I take it you mean honda, nissan and toyota.

    I really hope the american car companies get there shit together, the f-150 was the best truck out for a long time but not anymore.

  7. The ford is the best selling because it is the cheapest. Any yahoo that wants a truck can get a f-150. Which is good, there should be a nice cheap basic truck out there for everyone. Now, how does ford MAKE it the cheapest? Do your own research, you wont believe me if I tell you.

    p.s. the tundra is not an import, its made in San Antonio with a higher ratio of domestically made parts than any other truck manufacturer.

  8. Why are you always bitching about Japanese trucks? Competition is good because everyone tries to be better than the other. The customer wins, if there is not any competition the trucks would still be under 300 hp and four speed transmission. I bought a truck that is best for my money and I don't care who manfactures it. I work for my money and nobody tells me what to buy.

  9. i love american cars but the tundra does have a strong engine but everyone ik has problems with there transmissions, and there almost all under 60k

  10. i just bought a 2010 4.6 litre tundra. so far, so great! 400 miles on it so far. drives great, plenty of power. and yes, it can tow people. i'm not hating on other brands of trucks. I JUST KNOW THAT I LIKE THIS TRUCK. Smooth ride, but when i want to drive it offroad, it definatly takes the challenge well.

  11. No, racist would be saying that everything made in mexico smells like beans and rice. Istead, I'm saying Id rather support a company that employs Americans. Just like I'm sure people in Mexico would rather support a company that employees Mexicans, its call nationalism.
