Yes they are located front of block Remove air cleaner and fan and they become
easy to reach
Pull the wheel, pull the caliper and the rotor comes right off. You may have to tap the back side of it to loosen it up.
By the book, and probably the easiest way is to pull the pins from the hinges. There's a small retaining clip that has to be removed, then knock the pins out. It's a pain...especially the bottom side. Very little room to work. The other way is to remove the interior kick panes to access the bolt that can't be removed from the outside.
Your question needs a little more clarification. As far as bolting it in....nothing. They are pretty much the same engine. Are you replacing a 2.8 with a 3.1 that has the same fuel delivery system? Are you using one with the same computer control generation?
Check your battery. You may have one with a dead cell. You may need one with more amperage. If that is not it, there may be something wrong with your electrical system but it is probably a battery either going bad or too small.
To change the thermostat you must follow the lower radiator hose from the radiator to the "Y" shaped housing. To locate this housing stand in front of the vehicle, look directly down and to the left of the engine front.. it is pretty easily seen. it is above the ac/compressor. and in front of the water pump. All you need to do is remove the 2 bolts that hold the housing together, then separate the housing, pull the old thermostat out and clean the matting surfaces of the housing before you install new stat and gasket. After this, put stat in where you took it out... put new gasket on.. connect the two halves and tighten bolts... Job finished.
Map sensors can do some strange things. Most of the time the "limp home" mode will allow the car to run even if it does go bad. AutoZone will test that Map sensor for free. It will at least give you a place to start. There are several things that could cause your problem. Is the "check engine" light on?? yes the check engine light came on.
Ok....If you know how to do it, you can pull the codes yourself. The diagnostic link is mounted right next to the fuse box...just to the right of it. Mine is mounted verticle. There are two rows in the plug in. The upper two on the left row can be jumped. If yours is mounted horizontally, it's the upper row, right two. Take a paper clip or any type of small wire and insert each end into those two. Now, turn on the key....but do not start it. The check engine light will start to flash. The first code should be flash....pause flash flash. That would be a 12. That is just showing the ECM is in diagnostic mode. Each code flashes 3 or 4 times. Write them down. You can look up what the codes mean on the net or most any parts store can tell you. It's not as precise as the newer OBDII cars, but it will give you a place to start looking.....Hope that helps.
It is Fuse #14 in the fuse box located under the drivers side dash
it would be a really hard swap to go from the 2.8 to a 3.8. one the 2.8 is a 60 degree motor and the 3.8 is a 90. i am going to swap the 2.8 for a 3.4 because as far as power the 3.8 isn't much more powerful than the 3.4 and the 3.4 is a very straight forward swap almost everything is interchangeable.
if u'v opened the idle compensator on top of ur carb check for leak there
check the carb seat gasket for cracks and check bottom screws some of them will leak if they're not tight enough
