On the 1996-2001 Ford Crown Victoria, the plastic intake manifold on the 4.6L V8 is prone to cracking near the thermostat housing crossover, causing coolant to leak externally or internally into the engine oil. This was subject to a class action settlement.

This issue also affects: Audi A7, Audi Q5, Audi Q7

Common Symptoms

Coolant loss
Overheating
Coolant smell
Visible crack near thermostat housing

How to Fix

Pressure-test the cooling system and inspect the intake manifold around the front coolant crossover/thermostat housing area, as the original all-plastic 4.6L manifold commonly cracks there and can also leak coolant into the spark plug wells or intake ports. The proper repair is to replace the complete intake manifold assembly with the updated Ford or Dorman design that uses an aluminum coolant crossover, along with a new thermostat, intake gaskets, heater hose O-rings, and fresh coolant; change the engine oil as well if any coolant contamination is suspected. During installation, clean the cylinder head sealing surfaces, torque the manifold bolts in sequence to spec, and verify there are no remaining leaks after refill and bleed. Typical repair cost is about $700-$1,200 at a shop, or roughly $250-$450 in parts for DIY depending on manifold brand and related hoses replaced.

On the 1992-2011 Ford Crown Victoria 4.6L 2-Valve, the 4.6L 2-valve engine uses spark plugs that thread into aluminum heads with only a few threads of engagement. The plugs can eject from the head under load, stripping the threads. Later models (2004+) use a 2-piece plug design that can break during removal.

On the 1992-2011 Ford Crown Victoria, the Ford Crown Victoria equipped with rear air suspension (standard on LX and optional on base models from 1992-2011) suffers from premature air spring bag failure, compressor burnout, and ride height sensor malfunction. The rubber air spring bags deteriorate from heat, UV exposure, and moisture infiltration, developing cracks that cause slow or sudden air leaks. When the bags leak, the compressor runs continuously attempting to maintain ride height, which overheats and burns out the compressor motor. Strutmasters.com and CrownVic.net forums document thousands of cases. The rear of the vehicle sags noticeably, sometimes bottoming out on the bump stops. Many owners convert to conventional coil spring suspension as a permanent fix rather than replacing the expensive air suspension components repeatedly.

Common Symptoms

Rear of vehicle sagging or sitting lower than front
Air suspension warning light illuminated on dashboard
Compressor running continuously or cycling frequently
Loud compressor noise from trunk area
Harsh ride quality over bumps
Vehicle bottoming out on rear bump stops
Hissing sound from rear air springs
Uneven ride height side to side

How to Fix

Most cost-effective permanent fix is air-to-coil spring conversion kit from Strutmasters or Arnott ($200-400 for kit plus $150-300 labor). Conversion eliminates all air suspension components and maintenance. If keeping air suspension: replace both air springs simultaneously ($150-250 each), compressor ($200-400), and check all air lines for cracks. Strutmasters FA1R0 or FA3RB kits are the most popular conversion options.

TipThe most popular permanent fix is the Strutmasters air-to-coil conversion kit (FA1R0 or FA3RB depending on year). At $200-400 for the kit, it costs less than a single air spring replacement and eliminates the problem forever. Ride quality is comparable to the air system when functioning properly.
NoteIf your compressor is running constantly (you can hear it cycling in the trunk), shut it off using the air suspension switch in the trunk before the compressor burns out. A burned-out compressor costs $200-400 on top of the air spring replacement.
