Ignition lock cylinder failure.

EVAP Emission Control System

When did you change your plug wires last?

The 3.8 liter for this year has a plastic intake manifold. These manifolds are known to fail around the EGR port. When this happens coolant will leak into the intake right behind the throttle body. Dorman makes a replacement upper plenum that has been reinforced in this problem as along with a new gasket and an updated EGR tube. This will more than likely solve your issue. If you see a little coolant behind the throttle body this repair needs to be done ASAP. If this area completely ruptures it will hydroloc the engine. This means that coolant will fill one or more of the cylinders and the engine will not turn over/start.

It`s a heat shield,there should be plastic caps covering the screws to remove that to reach the starter.

Blowing out the exhaust. Look for white smoke.

check fuses and blower relay if thet check out replace blower motor and blower resister wile ur at it this is a togethe r type deal they work together

That means no fan. So check the fuses, try different fan speeds.

there is a hole in the pulley for the power steering unit. That hole accesses the bolts to drop this unit down and then you can change the water pump. The trick is getting these two bolts lined back up to reinstall it

need to jack the motor up after u take the bolts loose should be able to take it loose on the other end of mount two bolts ithink when jacking motor up be carfull not to dent oil pan

Try a new back up light switch /nuetral safety on the side of the transmission,where the shift linkage ends up.

need to perform a coolant pressure test. fill the reservoir and after the engine cools down fill the radiator, next start the engine and wait till the coolant system builds pressure then turn off the engine and using a mirror and flash light look for a leak.check water pump, hoses,radiator tanks for cracks,intake gasket at the corners espesically at the back next to the trans.also pull the carpet back and check for coolant leaking from the heater core,and last remove the sparkplugs and check for leaking head gaskets.hope this helped.

if it is the head gasket you should have steam or fumes coming out of the water jug as sone as you start the car. Check your fuel pressure regulator by removing the hose off of it. Does gas come out of the hose or regulator? if so replace the regulator. Hope this helps leave comment.

Bad rings or blown head gasket. You'll have to replace both to replace the rings so I would go ahead and replace the rings and Head gasket and have the valves checked while you have the head off. Paying a little more now is well worth it trust me.

check with your local police officer !

I'm not familiar with this specific model, but usually they are not too bad. There is a spring-loaded tensioner pulley, usually it has a hole for a 3/8 or 1/2 inch ratchet to remove the tension, then you just slip the old belt off, put the new one on following the same routing pattern. On a car this old, I would replace the tensioner at the same time, the spring could be weak and allow the belt to slip. Ask your auto parts store worker for more details. Usually the tensioner is held on with three or four small bolts, but you may have to remove the belt first to reach them.
