Is the UDP Visible?

Stillen sent me the wrong color and I was wondering if it's visible when looking at the engine or if it's hidden from sight.

You need to buy one new belt.

No, it's not visible. Unless you look really hard. Just install it.

Other IMPORTANT info that could potentially kill your car if not done (like it did to mine).

• 1995-2001 Maxima/I30 Only: Check 4 allen bolts that affix timing ring and make sure they are tightened fully.
• 1995-2001 Maxima/I30 Only: Check to see if stainless steel oil seal sleeve is mounted to the rear of the pulley.

Do they have to be the gates? Do I have to worry about those problems with a 2k2?

Sorry, I missed that part. I thought you had a 4th gen, but that's Vyrus, not Virus.

For a 2K2, don't worry about either of those problems. And it doesn't have to be a Gates belt, although I'm not sure what other kinds there are. Just make sure that the length and width are correct.

That's why I wanted to know what size the belts are. Do you know what factory spec is for the tension of the belts?

Ya got me. But if you bring that belt size to Checker/Pep Boys, they will be able to give you the correct one...... Sorry if that doesn't help.

I went to all the major stores and no one had any cross references to the gates part numbers. Pep Boys is a joke here in Manassas. They are gonna end up closing up shop. The very last store I went to had the belts. Thank god for the mom and pop shops. Does anyone know what tension the belts need to be at? It says stock, but whats stock?

Ya got me, but Stillen severely underestimates the difficulty of the install. The power steering tensioner is a friggin nightmare. 3 bolts. Have fun.

I just installed a prototype ASP underdrive and here are some instructions I wrote for the job along with the belt lengths I used on my 2K2. This will especially help when it comes to the power steering. If I had it to do again it would be a piece of cake!

1. If a lift if not available jack car up sufficiently to perform work under car. Use jack stands for safety.

2. Remove front passenger wheel and tire.

3. Remove passenger side plastic splash guard for easy access to pulley.

4. Loosen 12 mm locking bolt on power steering adjuster. Head of bolt is facing toward inner fender well, perpendicular to adjuster bolt and just to the rear of power steering pulley. Access to this bolt is best from under car.

5. Loosen 14 mm power steering pump rotator bolt on engine side of pump. It is accessible behind rear precat with a swivel or series of swivels and long extension from center of vehicle. The oil line to the oil filter is directly in line with this bolt.

6. Turn 12 mm adjuster bolt clockwise, as in tightening, to loosen belt. This bolt faces towards the ground and is located on bottom of adjuster. Use a long extension and swivel for access.

7. Loosen 14 mm ac/alternator tensioner pulley bolt. This bolt is in the center of the pulley and holds the pulley to the tensioner bracket. With bolt loose tensioner pulley is free to slide up and down on bracket within the limits of the 14 mm adjuster hex bolt. Turn 14 mm adjuster bolt counter clockwise to loosen belt and clockwise to tighten.

8. With both tensioners in the loose belt position, remove both belts.

9. Use a pneumatic impact wrench remove 19 mm center bolt holding crank pulley to shaft. Pulley is free to remove.

10. Use motor oil to lubricate ASP underdrive crank pulley seal ring on pulley hub. This insures lubrication to the crank seal when installed. Install pulley by hand locating keyway groove to key. Insure that pulley bottoms out on the crank shaft.

11. Reinstall crank bolt and torque to 140 ft/lbs. Locktite 242 thread sealer is recommended on threads.

12. For ease of belt installation, adjust both belt tensioners to insure plenty of free play to belt. Install Gates belt part number K040292 (or equivalent) on power steering and K060408 on ac/alternator. Insure both belts are properly positioned in grooves in all pulleys.

(I'm guessing on this one, I just tighten it until it felt right to me. Might have to refer to shop manual for belt tightening)
13. Tighten belts until belt has 1/4" movement at center of belt. Do not over tighten. Remember the power steering pump 12 mm bolt turns counter clockwise, as in loosening, to tighten belt.

14. Reinstall splash guard and wheel.

Now wasn't that a piece of cake? Hahahahahah!

Nice instructions. I found the gates belts last night. Now the problem is finding a shop that is willing to do the work. I'm getting the same response everywhere: "2002 Maxima. That's a new car" Me: Duh. Not out loud. "Why would you want to put a pulley on a Maxima" Family car seems to be in the thought process.

I wish I had these instructions before I did mine. Everybody's instructions just said loosen tensioners and remove belts. Telling the location of the bolts helps! That was the hardest part, the old pulley came off easy with impact wrench.

Sorry I did not have these instructions written when you did your pulley. Maybe this information will help others.
