try putting in some fuel injection cleaner in the gas tank.

4.0 'shortstars' do not have a bleeder screw, they are filled at the surge tank which is higher than the coolant anywhere in the engine compartment-fill it to the full level when COLD, and check for pressure in the system when the engine is hot (squeeze the top hose, it should be solid, not easy to callopse). Your surge tank also holds pressure so your cap has to seal tightly with no leak through the overflow tube.

Need to replace your throttle control sencor, This controls the fuel flow to your engine, Best of luck to you.

Antifreeze leaking into ur oil is not good,this will mess ur eng. up very bad it sounds like u have a busted head gasket,u need to have this checked

Look for the vehicle speed sensor mounted on the transmission to be bad,this is the most likely cause.

The most likely cause,besides the speedometer being bad is the vehicle speed sensor in the transmission.It is mounted on the outside of the transmission and is fairly easy to replace.

This is a problem with the multi-function lever [the one with the turn signal and headlamp controls]. It needs to be replaced. Unfortunately, this is a somewhat expensive repair.

The main fuse panels [actually they are small black boxes] are located under the rear seat on the driver's side of the car. There is an auxiliary fuse panel on the extreme left side if the dash which you can see when the driver's side door is opened.

There's a blower control module on the passenger side of the car near the glove box which has failed.

There's a fuse under the rear seat labeled Inst #1 or Inst #2 which may be blown. Try that first and hopefully that will fix the problem. If the fuse keeps blowing, then you've got a real problem because that circuit runs all over the car [at least a dozen different locations] any one of which may be in trouble. Good luck!!

Head gaskets are quite common to fail on Auroras. If it leaks internally, coolant burns and causes a smell to exit through the exhaust.

To be honest, when the electrical wires and parts get wet, there can be all kinds of problems. The best advice I can give you is have it professionally scoped.

IF YOU DONT SEE STARTER UNDERNEATH CAR NEAR FLY WHEEL AND YOU HAVE THE 4.0L ENGINE STARTER LOCATED UNDER THE INTAKE MANIFOLD JUST LIKE THE 4.6L ENGINES IN CADILLACS.YOU HAVE TO REMOVE INTAKE TO REPLACE STARTER.

If fuse is good and motor is new then I would be looking at switch that operates your wipers. Double check your wiring also.

you need to have battery tested , then cables,

Check for power and ground to the blower motor

you don't fix them - they are not serviceable except for replacing. if they're bad they need to be replaced.

Hello bladresha: My name is Roger and I will help you. The water pump on the 4.0 engine is located at the rear of the motor inside of the water cross over tube. It does require special tools in order to remove and install. This pump does not bolt in or on to the motor. This is a twist and lock in pump. Just like the Cadillac Northstar motor. You will need to remove the upper hose housing from the crossover tube. Look inside of the housing and you will see the water pump. You will need to use the special tool in order to unlock the water pump. Pay close attention to the water pump when removed. There will be a notch in one of the ears. This is a location notch. The new pump must go in the same notch. I have attached a picture that shows the water pump location. Should you need further help please just ask. Please rate the answer. Thank You for using Fix Ya. Roger
