On the 1999-2003 Ford Windstar 3.8L V6, the 3.8L V6 intake manifold gaskets degrade and allow coolant to leak externally or internally into the engine oil. This is closely related to the head gasket issue and can lead to overheating and engine damage if not addressed.

This issue also affects: Audi S5, Cadillac DTS, Cadillac Eldorado

Common Symptoms

Coolant loss with no visible leak
Milky oil
Overheating
Coolant smell from engine bay

How to Fix

Replace both upper and lower intake manifold gaskets. Use updated Fel-Pro gaskets. Flush the cooling system and change the oil if coolant contamination is found.

On the 1999-2003 Ford Windstar 3.8L Essex V6, the 3.8L Essex V6 in the Windstar is notorious for head gasket failure, often caused by the aluminum heads warping from overheating. The composite head gaskets deteriorate and allow coolant into combustion chambers.

This issue also affects: Citroën C3, Acura TL, Audi A7

Common Symptoms

White exhaust smoke
Coolant loss
Overheating
Milky oil

How to Fix

Confirm head gasket failure with a cooling-system pressure test, combustion-gas/block test, compression or leak-down test, and inspection for coolant in the oil or steam-cleaned spark plugs. Repair requires removing both cylinder heads, checking the heads and block for warpage/cracks, machining or replacing warped heads, and installing updated head gaskets with new torque-to-yield head bolts; the cooling system should also be flushed and the thermostat, radiator cap, and any overheating-related components replaced as needed. Because overheating commonly triggers the failure, inspect the water pump, radiator, fans, and intake manifold sealing before reassembly. Typical repair cost is about $1,500-$3,000 depending on machine-shop work and whether engine damage has occurred.

On the 1996-2003 Ford Windstar, the Ford Windstar equipped with the AX4S (1995-2000) and AX4N/4F50N (2001-2003) automatic transmissions suffers from widespread premature transmission failure. CarComplaints.com records 140 complaints for the 2000 model year alone, and 166 problems for the 2003 model year, making transmission failure the single most reported problem for the Windstar. The AX family of transmissions in the Windstar struggles with lubrication problems, harsh 1-2 and 2-1 gear changes, torque converter clutch issues, and catastrophic internal failures. The torque converter clutch solenoid is a particularly weak point, causing shuddering and codes P0741 and P1744. Average repair cost is $2,190 at 102,200 miles according to CarComplaints.com data. Many owners report needing a complete transmission replacement or rebuild, with costs ranging from $1,750 to $3,100.

This issue also affects: Acura TL, Acura ILX, Acura MDX

Common Symptoms

Harsh or jerky 1-2 and 2-1 gear shifts
Transmission slipping or shuddering during acceleration
Torque converter shudder at 40-55 mph
Check engine light with transmission codes
Delayed engagement when shifting from Park to Drive
Transmission overheating warning
Complete loss of forward gears
Grinding or whining noise from transmission

How to Fix

For TCC shudder only (codes P0741/P1744), start with transmission fluid change and TCC solenoid replacement ($400-800). For complete transmission failure, remanufactured transmission replacement is the most common solution ($1,750-2,500 installed). Jasper and Ford Motorcraft remanufactured units are the most commonly recommended. Rebuild is an option at $2,000-3,100 but ensure the torque converter is also replaced. Preventive: change transmission fluid every 30,000 miles - the Windstar transmission runs hot and degrades fluid rapidly.

NoteThe Windstar AX4S/AX4N transmission is one of the most failure-prone transmissions Ford ever produced. If you own a Windstar, change the transmission fluid and filter every 30,000 miles without fail. The transmission runs extremely hot in this van and fluid degrades faster than normal maintenance intervals suggest.
TipIf replacing the transmission, insist on a remanufactured unit with an updated torque converter, not a used junkyard unit. Used Windstar transmissions are almost guaranteed to fail again. Jasper remanufactured units come with a 3-year/100k warranty and include all known updates.

On the 1998-2003 Ford Windstar, the Windstar rear axle is prone to stress fracture and complete breakage at the spring perch, causing the wheel to tuck under the vehicle. This was subject to NHTSA recall 10V-040. Rust and corrosion in northern climates accelerates the failure.

Common Symptoms

Clunking from rear
Rear end sway
Visible rust/cracking on rear axle
Uneven tire wear

How to Fix

Inspect the rear beam axle closely at both spring seats/perches and trailing arm attachment areas for perforation, heavy scaling, or cracks; if any corrosion damage is present, the axle should not be welded for repair and must be replaced. Ford’s recall remedy for affected 1998-2003 Windstar vans was installation of reinforcement brackets if the axle passed inspection, or complete rear axle assembly replacement if cracking or severe corrosion was found, followed by a rear alignment check and inspection of shocks, brake hoses, and rear tires for collateral damage. If the recall is still open, the repair may be performed at no charge by a Ford dealer; outside recall coverage, typical owner-pay cost for a complete rear axle replacement is about $1,200-$2,500 depending on parts availability, rust severity, and labor.

On the 1995-2003 Ford Windstar, power window motors and regulators fail frequently, especially on the driver's side. The plastic guide clips break, causing the window to drop into the door or operate very slowly.

Common Symptoms

Window drops into door
Slow window operation
Grinding noise
Window won't stay up

How to Fix

Replace the window regulator and motor as an assembly. Aftermarket units are widely available and more cost-effective than OEM.
