Question about 2012 Honda Accord - Coupe, 3.5L V6 - Pro-Kit Lowering Springs

1 Answer

"Underdrive Pulley" Hello, I am thinking about putting on a "under drive pulley" on my 2012 V6 Accord Coupe, to gain a few more horsepower. It is of course smaller, and made out of Aluminum. And will need a new belt. Any Pros or Cons for doing this? Thank You so very much.

The pros to doing this are that it is an easy way to gain a little power, the cons are that whatever you put them on are now running slower than they were so they will not be as efficient as they were. The alternator won't charge as well, the power steering system won't have as much assist, etc. Some might be more noticeable than others. If you have a stereo system in the car with amps and subs, it would definitely be a drain on the charging system but if there aren't any accessories installed like that, it shouldn't be a large change. I'd go for it since it's an easy reversal if you don't like it.

Testimonial: "Many Thanks "forddoc94," no big stereo, have LED fog lights, turn signals front and rear, backup lights, interior. And my car is an Automatic. Can also go with LED's on my side markers too. Oh and my rear lights have LED's in there also. I also assume that the AC would also take a hit somewhat. I live in Iowa, and the humidity does get high also. My Honda Dealer was adamantly against putting it on, "what if your water pump goes out, what if you need to change your Timing belt." All kinds of "what if's." My comment back was "What if your Aunt had Nuts, then he would be your Aunt." :) They also brought out a 5 foot breaker bar they said they use to remove the nut on the pulley. I didn't understand that, unless it would crack while installing. Plus I found a Federal Law that protects us "upgrader's" that says if something goes wrong with your vehicle, the Dealer has to prove that the after market item caused a failure relating to an after market part. I can't think of it off hand, but will look for it. Thank You very much for your answer, as the pulley has been in a box since June of 2012. Have a wonderful New Year. johne"

Serpentine belt diagram mazda

2012 Mazda 3 I touring Skyactiv - Takes a 38" 6 groove serpentine belt- Very hard to find. The only place I found besides the dealer it Advance Auto but they had to order from the warehouse. There are three grooved pulleys and a smooth tensioner. To relieve the Tensioner you will need a shallow 17MM socket, it is a bit difficult to see, but if you stand on the passenger side the mount point for the socket is to the left of the tensioner shock. The Tensioner shock is just above the smooth tensioner pulley. All the threaded pulleys' (Drive, A/C, and alternator are within the serpentine belt, the tensioner pulley is outside the belt pushing down on the belt. The easiest way to replace this belt, First remove the old belt by placing the socket on the mount point and pulling up on the ratchet towards the rear of the car, then pull belt off. Next remove socket, place the belt over the drive pulley (this is the one on the bottom to the rear of the engine. ( you will see there is another belt on this pulley on the back side.), then put the belt over the A/C pump bottom front. Keep tension on the belt so it stays in place. Now put that socket back on, push up to lift the tensioner pulley and slip the belt over the alternator pulley. Make sure the belt is sitting properly on each pulley and under the tensioner pulley. Good luck. I have run into quite a few problems finding parts and information for this particular model. Good luck. Hope this was helpful

Not charging

Most likely this is due to bad diodes in the alternator. The diodes go bad due to time, heat, or attempting to charge a completely dead battery using the alternator alone. What does the battery indicator in the Camaro dashboard read? Does it get better with increased RPM? The RPM question is because, some 3rd generation Camaro owners would put "underdrive pulleys" on their vehicles. This would make the crankshaft, water pump, and alternator run slower to reduce horsepower drag. I had to switch back to a standard alternator pulley because my battery would die in traffic with the underdrive pulley. I hope this helps.

I hear humming under my hood. i have a 99 honda accord. i heard it earlier while i was driving through the drive thru .... i opened up the hood and i can hear it when i parked.

Most likely cause is a pulley going bad. Very possibly the alternator, power steering pump, or a/c compressor going bad. Could be just an idler pulley or the tensioner pulley.

The power steering pump should have a couple of retainer bolts, and then one adjuster bolt. Loosen the two retainer bolts slightly, then adjust the pulley back out of the way, slip the belt on, and use the power steering pump to tension the system.

Focus Sport Underdrive Crank Pulley Installation This How-To Library article is for the FocusSport crank pulley, which as indicated on the FocusSport product information page, includes a 6061 aluminum lightweight crank underdrive pulley and a new Goodyear Gatorback accessory belt. The FocusSport crank pulley underdrives your accessories by 23%. This, in turn, decreases the drag on the engine, unleashing power that you never knew you had. And since the FocusSport (7.6 ounces) crank underdrive pulley is lighter than OEM (3 lbs. 4 ounces) crank pulley, you'll benefit from the weight reduction of rotating mass; resulting in a more responsive engine. FocusSport crank underdrive pulleys come in a red anodized finish. (Product description taken directly from the FocusSport product page...)

car-raised-small.jpg Note: It helps to have the car on a lift before you begin, though not too high up, as you'll need to get at teh top of the engine bay under the hood. If you don't have access to a lift, use a 2 ton jack stand.
  1. Remove the plastic splash guard inside the right front fender well.
    • There are two 10mm bolts holding it to the fender.
    • After removing the bolts, it should pop right out.

  2. Remove right front wheel.
  3. Remove the bolt on the crank pulley
    • Use an impact wrench if you have access to one.
    • This bolt is a regular right-hand thread.

  4. Install the new pulley on the crank.
    • There is a keyway on the crank that the pulley must fit over.
    • Push it firmly into place by hand first, to avoid binding when you torque it.

  5. Torque the bolt to 85-91 lb-ft.
    • This is tricky if you don't have an impact, so try to find one.

  6. Relieve the belt tensioner and route the new belt over the pulley and accessories.
  7. Reinstall the plastic splash guard.
  8. Put your front wheel back on.

2001 mitsubishi mirage engine will crank but it wont start. Was told to change the crankshaft position sensor. Would like to know how

I have changed the crankshaft position sensor a few times and I tell you it is no easy task. It requires almost damn near pulling the motor out of the car. The sensor is located under the timing belt behind the underdrive pulley. This will require you to pull everything off the car on that side of the motor including the motor mount so have a jack with a piece of wood ready to support the motor.(First take off your battery cables) Once you remove all components the remove the timing cover, loosen the timing tension pully (be careful of the spring) try not to remove the timing belt or be ready to re-time it. you will see the crankshaft sensor down at the bottom behind the underdrive pulley. Its just two 10mm bolts that are not very easy to remove (be prepared to drop one and retrieve it). Unscrew the bolts and re-assemble everything (the hardest thing for me was tightining the timing pulley) This is the easiest way to do it short of pulling the motor completely out and removing the underdrive pulley which would require re-timing and special tools. I hope this helps.

I can't find the Auto-tensioner on my 99 accord. Does it have one? If not, how do i get the belts off?

I think this is right, but…
Find someone to help you if you can. To help hold the new belt in place when you are putting it on.
Make a diagram of the way the belt fits over and around the pulleys on your car. Don’t thing that you are going to remember where it goes.
Locate the drive belt auto-tensioner on the upper part of the engine (see pic). The tensioner is an idler pulley, since it does not drive any accessory on your vehicle. Its only function is to give the belt its proper tension.
Insert a long boxed-end wrench on the auto-tensioner pulley bolt of the appropriate size (probably 14mm) and slowly turn the idler pulley to release the tension on the drive belt (you are not removing the bolt; you are turning the tensioner so you can get the belt off while you have it turned under pressure). If you have a 2.4L engine model (2.3 Vtec should be similar), turn the pulley clockwise; if you have a 3.0L engine model, turn the pulley counterclockwise. Slide the belt off any pulley located on the upper part of the engine while you have the tensioner under pressure; then slowly release the tensioner pulley and remove the belt from the engine.
Check every pulley run by the drive belt and make sure they are free of dirt, debris and built-up material.
Compare the old belt to the new one and make sure it is of the same width and configuration.
Install the new belt beginning with the crankshaft pulley at the bottom and center of the engine and work your way up to the last pulley; follow your notes or the routing diagram on the engine compartment. If necessary, ask your helper to hold the belt stretched next to the last pulley on the upper part of the engine. Using the boxed-end wrench, slowly rotate the auto-tensioner pulley in the same direction you turned it to release the belt. Then slide the belt over the last pulley, and slowly release the auto-tensioner.
Make sure the belt is properly seated between the flanges of every accessory pulley.

Need diagram showing timing adjustment for a 1992 honda accord 2.2 engine see no timing marks how do i set timing

Check the position of the timing marks. The timing pointer mustbe perfectly aligned with the TDC (white mark) on the flywheel orflex-plate; the camshaft pulley must be aligned so that the word UP isat the top of the pulley and the marks on the edge of the pulley arealigned with the surfaces of the head. Additionally, the face of thefront timing balancer pulley has a mark which must be aligned with thenotch on the oil pump body. This pulley is the one to the left crankwhen viewed from the pulley end.
