The 2007 Ford Freestar, built on the aging Ford U platform with either the 3.9L or 4.2L Essex V6, is notorious for catastrophic head gasket failures and transmission cooler line corrosion that can destroy the transmission. These are not 'if' problems—they're 'when' problems that make this one of the riskiest minivans to own past 100k miles.
Head Gasket Failure (Both Banks)
Common · high severity
Typical onset: 80,000-140,000 mi
Symptoms: White smoke from exhaust, especially on cold start, Coolant loss with no visible leaks, Milky oil on dipstick or under oil cap, Overheating or rough idle as coolant enters cylinders, External coolant seepage between head and block
Fix: Both heads must come off due to the V6 design—you don't do one side on these. Requires head removal, resurfacing (often warped 0.008-0.015 in.), new gaskets, and typically new head bolts. Budget 14-18 shop hours. If coolant contaminated the oil long enough, you're looking at bearing damage and a full rebuild. Many shops won't touch these anymore without quoting engine replacement up front.
Estimated cost: $2,800-4,500
Transmission Oil Cooler Line Corrosion and Cooler Failure
Common · high severity
Typical onset: 90,000-150,000 mi
Symptoms: Pink or red fluid in coolant overflow tank (cooler leak mixing ATF and coolant), Transmission slipping or delayed engagement after cooler contamination, Rust-through of steel cooler lines at radiator connections, Transmission overheating from blocked cooler passages
Fix: The internal trans cooler in the radiator corrodes, allowing coolant into the ATF—this is a transmission death sentence if not caught immediately. Requires radiator replacement, cooler line replacement (they rust from the inside out in salt states), complete transmission flush, and often a transmission rebuild or replacement because coolant destroys clutch packs and bearings. If you catch it early (just cooler leak, no slipping), you might escape with radiator, lines, and flush—8 hours. If contamination reached the trans, add 12-20 hours for trans R&R and rebuild.
Estimated cost: $1,200-5,500
Intake Manifold Gasket and Runner Control Failure
Occasional · medium severity
Typical onset: 70,000-120,000 mi
Symptoms: Coolant smell from engine bay with no visible leak, P2004/P2005/P2006 codes for intake runner control stuck, Rough idle and poor throttle response below 3000 RPM, Coolant loss traced to lower intake area
Fix: The composite intake manifold gaskets fail, leaking coolant internally or externally. The IMRC (Intake Manifold Runner Control) actuators and linkage seize up from carbon and heat. Intake removal on these V6s requires pulling the upper plenum and dealing with brittle plastic connectors. 6-8 hours for gaskets and IMRC actuator replacement, plus cleaning carbon from runners.
Estimated cost: $900-1,400
Harmonic Balancer Separation and Wobble
Occasional · high severity
Typical onset: 100,000-160,000 mi
Symptoms: Visible wobble of balancer pulley at idle, Squealing belt that won't stay aligned, Rough vibration at idle that smooths out at higher RPM, Outer ring separated or visibly offset from inner hub
Fix: The rubber bonding layer between the inner hub and outer ring deteriorates, causing the balancer to wobble or completely separate. If it flies apart, it takes out the radiator, AC lines, and can crack the timing cover. Replacement requires special pulley puller and installer tools. 2-3 hours if caught early; add time if it damaged accessory drive components.
Estimated cost: $400-800
Rear Transmission Mount Collapse
Common · medium severity
Typical onset: 60,000-110,000 mi
Symptoms: Clunk on acceleration or deceleration, Excessive engine/trans movement visible when shifting from Park to Drive, Vibration through floor at idle in gear, Shifter feels vague or notchy
Fix: The rear trans mount (under the trans tail) fails frequently from the weight of the 4-speed automatic. The rubber tears and the aluminum bracket can crack. Requires lifting the trans slightly for access. 1.5-2 hours. Do all engine/trans mounts at once if budget allows—the others aren't far behind.
Estimated cost: $250-450
Camshaft Position Sensor Failure and Cam Walk
Occasional · medium severity
Typical onset: 80,000-140,000 mi
Symptoms: P0340/P0345 cam position sensor codes, No-start or extended crank time, Stalling at idle after warm-up, In severe cases: metal shavings in oil from cam thrust bearing wear
Fix: The cam position sensors fail electronically, but the real issue is cam endplay (cam walk) on high-mileage engines due to worn thrust plate and bearings. Sensor replacement is 1 hour, but if you're seeing metal in the oil, the cam is walking and destroying the timing chain and thrust surfaces—requires heads-off teardown or engine replacement.
Estimated cost: $180-350 (sensor only); $3,500-5,000 (if cam walk damage)
Owner tips
Change coolant every 30k miles with proper Ford Gold coolant—these head gaskets are on borrowed time and clean coolant buys you maybe 20k more miles
Inspect the coolant overflow tank monthly for ANY pink/red tint indicating trans cooler failure—catching it early saves $3,000+
Replace the harmonic balancer preventively at 100k miles; the $300 part is cheaper than the $2,000 collateral damage when it grenades
If buying used, pull the oil cap and dipstick immediately—any milky residue or coolant smell means walk away, the heads are already cooked
Budget $500/year for surprise repairs after 100k miles; these don't age gracefully
Hard pass unless free and you're a masochist—the head gasket and trans cooler issues are catastrophic, expensive, and nearly inevitable, making this the minivan equivalent of financial self-harm.

Ford is recalling certain model year 2004-2007 Freestar and Mercury Monterey vehicles manufactured from March 24, 2003, through November 7, 2006, equipped with a third row seat and originally sold in, or currently registered in, Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin and the District of Columbia. The third row stowable seat can experience corrosion and structural degradation at the seat anchor mechanism mounted to the rear wheel wells. As a result of the corrosion, the third row seat may not fully latch into its seating position.
Consequence: In the event that the vehicle is crashed into from the rear, an unlatched seat may increase the risk of personal injury.
Remedy: Ford will notify owners, and dealers will install new third row seat latch striker mounting brackets, free of charge. The recall began on March 28, 2013. Owners may contact Ford Motor Company Customer Relationship Center at 1-866-436-7332.
