I couldn't see it as I looked for it from the right front wheel well or looking under the front bumper, etc. I had to lay on a creeper and roll under the car. The filter is on the passenger side, near the front tire. It's easiest reached and unscrewed with a filter wrench. The filter wrench is available in a parts store and is shaped to fit like a cap over the top of the filter. It is about three inches in diameter, about an inch deep and has 15 flats around its circumference to grab the flats on the top of the filter. It has a 3/8" square hole in the top to accomodate a 3/8" ratchet wrench. You'll need to use a 2" extension with the wrench in order to get the ratchet clear of the auto frame in order to turn it. Be prepared for a litte mess, because the oil that drips as you unscrew the filter will drip onto the frame.
Engine starving for fuel is a symptom. Best thing to do is replace it according to the maintenance schedule in your owners manual. They are not fixable only replaceable.
only if it doesnt have fluid.
I would say NO ( I was looking at the 2001 Lincoln Navigator Owner Guide and it does not show anything about it having a cabin air filter )
Brake Booster needs replaceing
On a 1991 Lincoln Continental : I'm not a mechanic / technician but I have never heard of aluminum heads for the 3.8 litre Ford V6 engine So , I would assume they are cast iron
Its inside the passenger side front fender. Remove the plastic cover. Replace as you would any other Lincoln filter.
Would have been built for R12, can be converted to R134a.
You might need freon
That would be found on the transmission where the linkage hooks up.
No, as being a master mechanic, it would have nothing to do with it.
It isprobably not getting fuel or not getting spark.
