Well I finally installed my Steeda underdrive pulleys. It was easier than I thought it would have been. The hardest part was keeping the crankshaft from turning. The power gain is very noticeable. I have to say, dollar for dollar, it is probably the best way to add HP. For those who are interested in how I did it, read on.
1. Disconnect the battery, take the belt off the alt pulley and disconnect the wires going to the alternator. Because of the coolant crossover tube, you must remove your alternator. (or, if your weird, leave the alternator on and disconnect your crossover tube.) Using Marine ingenuity, Secure the alternator from spinning, and remove the large nut on the front of the pulley. At this point, my pulley literally fell off of the shaft, but you might need to use a puller. (which I bought beforehand). Install the new pulley on the shaft, and securing the shaft, tighten the nut. Next, there are 4 10mm bolts holding the water pump pulley on, I grabbed the back of the pulley and used a socket to get these off, easy as pie. Now that it's off, reinstall the alternator and secure it. If you put the new water pump pulley on before the alternator, you will have problems tightening the alternator down. Now that the alternator is on, and tight, plug it back in. NOW put on the new water pump pulley. Tighten it as best you can, later when the belt is on you can use it's tension to hold the pulley tight enough to torque these down. It was about this time that I busted my right ring finger middle knuckle awfully bad. I should go get stitches, but that takes time away from my car. Now, jack up one side of the car, and put a jackstand under it. Remove the inspection pan cover from directly behind the oil pan. It has 2 8mm bolts. Now stick something between the flywheel (flexplate for those who believe a flywheel is for standard transmissions) and the transmission housing. Or, if you have an impact wrench (which I dont, and didnt really need) loosen the 18mm bolt on the front of the crankshaft pulley. Unplug the fan, and loosen the 2 8mm bolts holding the fan housing on the radiator. Pull the fan housing out of the car. You do not have to remove the drivers side radiator hose. Use some bearing grease on the hose and the fan will slide out. Using the harmonic balancer puller that you will need before hand (I picked mine up a day earlier)remove the old, fat, heavy, stock pulley. Using the large washer that was on the 18mm bolt you pulled out, use the long bolt supplied with the new pulleys and tighten it down. This draws the new pulley onto the crankshaft. ****MAKE SURE YOU ALIGN THE KEYWAY**** DO NOT TIGHTEN ALL THE WAY. This bolt is used only to pull the new pulley onto the crank. Once the bolt bottoms out, remove it, use the same washer on the new bolt (the shorter one) and torque it down to the specified amount. I used the tried and trued method of 2 grunts and a fart. It's not as precise, but it works miracles. Now that all the pulleys are back on, reinstall the fan, plug it back in. Replace the belt onto all the pulleys. Notice I didnt mention anywhere that you need a new belt. You dont. Once the belt is back on properly, remove whatever you used to secure the engine from turning, and lower the car. Check everything over and reattach the battery.
It took me 45 minutes, I used hand tools, and I did it by myself. The only thing I needed was the harmonic balancer puller. Pulling the fan out was the only way to get the old pulley off and the new one on. I would say this was slightly harder than a brake job, but way easier than a rear main seal. Next up is my motor mounts, but I have 2 weeks before I leave for Iraq, so I doubt I'll get to it. :L
