Fuel Filter problem & recommended tire pressure?

First of all, Happy Holidays to ALL

1999 Grand AM SE 3.4L V6

I have 3questions:

1. What is the recommended tire pressure? GM says it should be 30psi but Jiffy Lube recommend 35psi. I have just replaced all 4 tires to the Dayton UNI-T. Any comments on that?

2. I went to GM to have my fuel filter replace but was told that the clip was broken. I have to buy the whole fuel sending unit (part#25317984) and will cost me over $500 (parts & labor) to have it replaced? Is that justify? It is a lot of money. Will driving with a old filter damaged the engine???

3. Tranny fluid change? I went to GM and they says that it is not necessary (I have 66000 miles) They recommend that a change @100,000 miles for my model??? I have read in this forum that change every 30000-50000miles.

Thanks

Go by what's on the sticker on your door.

Have them show you the broken clip. If they're talking about the small clip that holds the filter to the line, that is total and complete BS!!! It's no big deal to change this yourself - especially if the clip is already broken. That thing is a pain in the but to get off. You'll see what I mean if you want to try to change the filter yourself. A regular hose clamp would work just fine. And if you buy a filter at a store, you'll need to remove any connectors already attached to the filter. If you don't want to do it yourself, I'd definitely take it somewhere else that won't try to screw you like this.

Unless you're having problems or are wanting to go synthetic, you really shouldn't have to change it.

I agree with the door sticker for your tire pressure. First you should always go with what the car maker says next follow what the tire maker says in that order. Never listen to Jiffy Lube!

Your fuel filter should get changed the gas you buy has alot of dirt and stuff in it. And no a hose clamp will not hold the fuel line on. Do not even try using a hose clamp on it. Your fuel line is made of a type of plastic which has a real hard end on it (some cars have a metal collar on them.) to lock the clip to the filter you will not get a tight lock on the filter with a hose clamp. GM does not sell the clips seperately they should but don't you have to buy the whole pump unit to get the clip. I would reccomend you visit a junkyard and get a clip off a junk unit. It would be chaeper and alot less work to replace the clip then to replace the pump.

Who ever told you that your trans fluid is good for 100K was wrong your trans filter is good for 100K the fluid is good for 30K.

Here's the perfect example of a mechanic's point of view vs. the real world. Remember, they are not in the business of making people's lives easier. Rather, their's is a world where the means are outrageous parts and labor costs with the end being their big fat pockets.

If you are familiar with the clip that holds the fuel filter on you would know that it slides out of the fitting at the end of the line for easier removal and installation of the filter. That would also tell you that I didn't mean to wrap a hose clamp around the whole line and crank it down on the filter. I can take a picture, if you would like, of the $.10 hose clamp I inserted in its place.

But you're right, he should probably just buy a whole new pump and sending unit to be on the safe side. :disappoin

In reply:

It is the technician at GM (Colma Pontiac, Daly City, CA) who says that I do not need to change tranny fluid until 100000 miles. So he says that my car was a newer 99 model. Does that make sense?

tire pressure man you should always look at the tire to see what the max PSI the tire can hold. never assume tire pressure is the same for every tire because every tire is slitley different. You can find the tire pressure for any tire, by the bead(the closes part to the rim), its typed in small font. it will tell you the max psi on cold tires(tires that have been sitting for about more than an hr) becaust the warmer tires the psi increases. So to get accurate readings, try filling up on cold tires. thas what i've learned. just sharein' to you. don't want your tires to blow from over fill
