The problem with going into auto mechanics is that A: It's a fairly crappy job on the best day, what with being hot in summer, cold in winter, always being dirty, always scraping your knuckles, cutting your hands, burning yourself, etc., dealing with stupid people who don't know what you're talking about, don't take care of their cars, don't trust you, and don't want to pay you, and B: You have to constantly be learning new stuff. Every new car that comes out is a new bag of problems, and your have to try to keep track of all their quirks, or you won't be able to diagnose obscure issues accurately. You'll be expected to work on stuff made last week as well as stuff made 40 years ago, and just "know" what's wrong with all of them, or you won't get any respect. Most of the best mechanics have been messing with cars since they learned to drive, it's not something you just decide to take up on the spur of the moment. I've been working on cars for 35 years in my spare time and as necessary, and I don't know that I would ever have wanted to do it for a living. I've known some really good mechanics who've thrown down their tools in disgust and walked out, it was that bad. While I think it's true that any job is what you make of it, it's not a glamorous, high paying job. It's hard, dirty, sometimes dangerous, and you're expected to pull your own weight. In a work environment that's 99% male, you're going to get a lot of lonely guys hitting on you, or just resenting you for being there. They're going to be angry they can't tell their crude jokes with you around, or maybe they will anyway, and you'll have to put up with it. As a woman, you're going to have to be twice as good to be noticed, much less taken seriously, and any mistake is going to get twice as much attention. I'm not trying to discourage you, but just bear all this in mind.
I had a 87 with a 2.9 and a 5 speed. It was great. Went through mud. The electric lockouts sucked but just convert them to manual locking hubs. The 2.9 is bulletproof accept the head. They had a problem with leaky valve cover gaskets but no biggie.
If it has the slip yoke rear driveshaft (looks like a CV shaft) they suck but you can get a regular U joint shaft to make it stronger. No biggie. I loved mine and took a pounding.
well now you've heard a stupid answer see if its the bypass hose or heater hose could be a head but i'd let it get warm full of water look for the leak make sure its not a cracked thermostat housing
make sure you have a spring loaded radiator cap that meets the specks for your vehicle. the cap opens at certain pressures [usually above boiling] and releases coolant into the over flow tank and later the coolant is sucked back into the radiator. this is normal. installing a lower t-stat will usually enhance the problem because the coolant will not stay in the radiator long enough to transfer away the heat properly. it could be other things causing the problem, and the heads are the same so don't worry about that statement. any time you bore a motor you thin the cylinder walls allowing more heat to enter the cooling system. this can be a big problem in high performance engines so that's why the parts boys sell high dollar aluminum radiators. anyway good luck on solving the up chucking ford. by the way is that the original motor? how about the radiator?
The car runs some tests of the emissions system as you drive it. Sometimes these tests require several hundred miles of normal driving to complete, or specific types of driving, called a "drive cycle". For example, some tests might require the car to be warmed up and going over 35 mph for a certain amount of time.
OBD means On Board Diagnostics. Having OBD tests not complete means the OBD system hasn't had time to complete all its tests. This can happen if the battery was replaced or run dead recently.
http://www.justanswer.com/cadillac/2ujzp-need-drive-cycle-cadillac-seville-sls-2001.html shows a drive cycle. You just need to do the ones related to the catalyst (5 minutes of steady 55-60mph). That should take care of your evap system also. If not, do the ones that say "EVAP purge" also.
