Coolant Leak/Overheating Due to Radiator Leak on Ford Explorer

A coolant leak may develop from the radiator. Ford has released and updated radiator and powertrain control module (PCM) software update to address this issue. The software update includes revised cooling fan operating parameters. Failure to complete both service procedures may result in repeated radiator failures.

Same problem like everybody else here. Bought it used 1 1/2 years ago with 118,000 miles. I filled up the coolant of my Explorer every couple of weeks for the last months and last weekend all the coolant was under my car. Ford replaced the radiator and 2 hoses, they charged me $1,300. I don't know if the previous owner had the same problem already. Fortunately (because of this site) I knew about the PCM software update and after telling them they double checked it and found out, that my car needs the update. What if I didn't ask? I'm just glad that this didn't happened during my 3,000 mile road trip a month ago (especially in the Death Valley).

Engine kept "reving" when accelerating out of low gear. Had transmission serviced twice without any resolution. Finally drove car around with tech and diagnostic computer. Saw temp gauge going up and down slightly when accelerating. Checked radiator and found crack in seam. Clearly a defect but ford would not cover repair. $900 to replace radiator with only a 1 year warranty.

08/01/2015 - Took car for regular oil change at our local Quicklane and found out that plastic intake manifold is cracked. The total cost with parts and labor $510. I am writing this report as I am waiting for the vehicle to be fixed. After reading multiple reports online, it seems like this is a very common problem with Explorers and relate to design/manufacturing problem. I checked with the service manager to pull a report for extended warranties by Ford on this part he found none for this particular part. Very disappointed with the product.

Check engine light went on & What I initialed thought was an oil leak, it turned out to be antifreeze on the ground. The local mechanic replaced the radiator & is taking it to a ford dealer for a software update which includes new cooling parameters. Hopefully this will keep it from happening again.

replaced radiator
All the coolant leaked out onto my garage floor overnight. Repair shop replaced the radiator and mentioned that radiators for 2006 Ford Explorers are becoming hard to locate due to the number of complaints that are being reported recently. I contacted the Ford dealer prior to getting my vehicle into a nearby shop. The Ford service reps never bothered to get back to me on this problem.

Radiator leaks. The radiator repair man says Explorers are notorious for this, sometimes needing radiator repair/replacement every other year.
Car needed a new radiator, due to leaking (driveway spots). Extended warranty purchased through CarMax covered all but a $50 deductible. Have read this is a somewhat common problem for this vehicle.
