I do not recommend that especially with you being stock. A hot engine is a good thing, it's efficient at operating temp. Don't change it.

so what temp should i get..
Stock temp thermostat. 195*
Stock engine + 180*tstat = worse MPG and no real performance gains
I believe my '01 GT has a 180* thermostat in it (not my doing...bought it like that). In the winter, my check engine light comes on. Code says that the engine is not reaching normal operating temperature. This is due to the 180 thermostat.Quote:

Good write up! luckily, my car isnt showing any of those symptoms (knock on wood)
Awesome tips. I am actually going to look at one today that the owner thinks needs head gaskets because of water in the oil. I'm thinking it may just be intake gaskets though.
Not a bad thread, although I wish a person who REALLY knows about w-bodies will go through it and fix a few of the things and list price ranges for fixing things. I mean, you see leaking elbows and some may think ah that's a deal breaker. No it's a $4 part.
The subframe does not have to be lowered. The motor mount must be removed and the engine temporarily supported.Quote:

you would think this list would deter people from buying them but if you are familiar you can get a good one and work on the little bugs and have a great car for years
* Rusted rear strut tower – This has been happening more often to cars in the “salt belt”, open the trunk and look back towards the strut towers, pull back the carpet and inspect the top of the tower for signs of rust.<<< I HAVE this problem it has actually broken through the body on the passenger side and rusted on the drivers but not as bad... I did not check this before I bought it although i checked the rest of the car so it was my bad.
* Rocker panels / lower door – The rocker panels are notorious for rusting out, crawl under the car and look at the rocker panel from behind the body molding, you’ll be able to see any signs of rust. Also the lower parts of the doors are known to rust, with the door open, look underneath them. <<< also this although I knew when I bought it about this.
I am trying to get a price on what it would cost to fix.
When your list of common problems doesnt even take up an entire thread I think its a good thing, there are cars out there that you can list the common problems and probably take pages.
To be fair he listed things only that you can visually find wrong, or test while at a dealer lot. Common problems that just pop up would add more close to filling a thread, like crank sensors, wheel bearings, etc.
No those are things that commonly go out on every car.

I guess. I still know that GP's are a little on the high end when it comes to the amount of parts that need to be replaced after 10 years. But sometimes it makes up for it with the prices of the aftermarket being fairly low.
Compared to any car that is over 10 years old a gp is probably the same as far parts that need to be replaced or break.

Thanks for posting this. Just what I was looking for. Plan on buying one by February.
I have started looking for a 98-03 GP for my wife who loves her 98 Grand Am (95,000 miles) that has become a money pit.
I do not want a car with a 3100 or 3400 so the SE is not an option.
Is there a reliability difference between the GT and the GTP?
Is there a year model I should avoid?
Is there a year model I should target?
Is there any option that is a deal breaker like maybe a sunroof that is prone to leak?
Great writeup. Thank you for posting it. I will have it memorized before I go tire kicking again.
No reliability difference between gt and gtp for the most part, although GTP's only have a few more parts than a GT (and a few more parts to go bad) Supercharger rotors, coupler, belt, tensioner, vacuum trees always break, etc. Still just about the same overall.Quote:

To target? Not really. Usually things always get better as a model gets later into production. In 2000 they put rear wheel well covers to help prevent strut tower rust, in mid 2003 the 4t65e transmission was updated with a few new style of parts that are more reliable, in mid 2005 the 3800's came with more reliable lower intake gaskets, and the 2004+ GP's are less prone to rust overall. 97-03 rots the rockers out in only a decade in the salt belt. Other than that they're almost the exact same car minus the styling. The series III 3800 which is 04+ comes with the electronic throttle body which always fails after the mileage gets up there.
No options are deal breakers really, the only options that usually have issues are leather seats wearing out, and the heads up display commonly fails if equip.
