I apologize beforehand for the newbie question but this is my first dealings the mod motors so I am still trying to learn as much as possible. I purchased a set of underdrive pulleys for my 05 gt..I was wondering if there was a difference in the underdrive crank pulley/balancer between the 96-04 and the 05's. The reason I ask is the invoice stated they were for the 96-04 and this company has already messed up my order one time ...any info on this would be greatly appreciated ..thanks

You will need a 3.5" pulley puller available from any auto parts store for $15 or so to remove the harmonic balancer. To put the new one on, many kits, including the Motoblue kit I installed, come with a disposable bolt. You use this bolt to get it on most of the way then use the real bolt to tighten. You also MAY need a breaker bar to get the harmonic bolt loose to begin with. I just used a piece of pipe and put one end of it over my socket handle to extend the handle by a few feet, giving me the leverage needed to loosen the bolt. An impact wrench would accomplish the same thing. Make sure your in 4th or 5th gear when doing this or you'll just move the car instead of loosening the bolt.

You'll have to remove the radiator fan to access everything, very easy, 2 bolts and it slides right out.

If you know a socket from a monkey wrench it should take you less than an hour and it really peps up the car. One of my favorite mods.

+1 on the breaker bar. It's not going to come off without that or an impact wrench. You should be able to rent a pulley puller from any good auto parts store if you don't feel like buying one.

I've been considering installing a lightened flywheel on mine- I can't stand how slow the engine rev's up, and then it takes forever to come down- difficult to match rev's while shifting.

Will the underdrive pulleys reduce time the engine takes to wind back down after releasing the throttle? Is it significant?

If anything it will make it worse due to less rag on the motor. I had the R{M Hold to. I do believe a lighter flywheel will help thign slow down quicker with less inertia.

I believe that you are correct- it would take longer for the rev's to come down.

I have had lightened flywheels in other cars- it completely changes the way you can drive the car- rev's are almost instantaneous (like a NASCAR engine).

Just a regular 3.5" pulley puller necessary. It is not threaded. A disposable bolt is usually provided to push it back on. Then tighten with the real bolt.

An extension to your wrench, like a piece of pipe will be needed to gain leverage needed to get it off. Or an impact wrench.

Wish I knew about the whole 4th or 5th gear thing. I was thinking 1st would hold it the best, WRONG, lol. Took a little bit longer than an hour.

There is also that Alternator bolt you need to replace that usually comes in the kit. If not it will rub on the belt, and thats not good!

Sorry to awake the dead with this old post, but I heard that the Chrysler puller works better than a ford puller for this install.... is that true? I'm installing mine in 3 hours and just wanted to double check.

also just wanted to check that I have everything that I will need for the install considering that once I take the pulleys off, I cant drive to the part store to pick up any last minute pieces to the puzzle. this is the list that I have gathered from reading all the old posts.

pulley install things needed/ to do:

- draw a diagram or take a picture of belt location.

- 3 jaw puller (3"-3.5"**)

- RTV gasket sealant

- some synthetic motor oil (for greasing up crank)

- Place car in 4th or 5th gear when loosening the harmonic balancer bolt

- impact wrench** or breaker bar

- pulleys and alternator bracket

- new crank bolt


am I missing anything? Would a harmonic balancer tool be needed? I think you can rent those, I have to rent the puller also.

I think you just about have it. I didn't know there were Ford and Chrysler pullers but I used a regular jaw puller. I used a 4", a bit big, 3 or 3.5 would be fine. I used synthetic grease instead of oil for the crank but I can't imagine that would be a problem. As for the beaker bar I just put a piece of pipe over a 1/2" ratchet handle and it worked great. Good luck. Pulleys was one of my favorite mods. They really pepped up my car.

well, it took a few more hours than planned and had some fun delays as always, but after 4 hours they have been installed and work great!
