So for years I've owned my Mountaineer & it seems to have been reliable. Aside from transmission shifting problems that feel like I'm being rear ended or slammed into gear, the sunroof leaks and the fix I was given BY A FORD DEALERSHIP is to park downhill. Recently a grinding sound from rear wheel bearings and told they are not bolted on & quite expensive. Automatic power running boards that cost me $1,500 to have repaired due to them staying extended. Broken spark plugs in cylinder head, exhaust manifold weld cracked, a thunking sound when making a hard right turn. Recently I smelled the sweet scent of radiator fluid. It would take months but I found myself adding about 1 gal of fluid.
I read up and saw some complaints of different things and investigated. I looked under intake manifold, a metal tube runs from front to back & can rot leaking fluid onto engine but won't see it due to leaking under manifold & evaporating. No fault seems to be found. I check front and rear heater cores, apparently rear core is known to rot away, no fault seems to be found. I did see some crusty hoses so i replaced all heater hoses & clamps. Still had the scent & then one day driving it overheated so bad it went into limp mode, when it shuts down 3 or 4 cylinders to avoid any potential engine damage, only allows vehicle to drive like 30 mph & check engine light actually blinks! That was the broken plug i found later. So back to the radiator fluid disappearing trick.
I call around and am told to replace water pump, thermostat and housing. Original was aluminum and replaced with plastic one because original developed hairline cracks and seepage. So I flush & replace & then come to go to a medical appointment (retired disabled veteran on ssd fixed income) and there's a puddle under my vehicle. No leakage from heater, upper or lower hoses though, water pump looks dry, but somewhere inside shroud is leaking. All over car complaints see problems with these radiators leaking, but they're all 4.0 models. But the same 4.0 radiators were put in (2006 4.6L mountaineers as well as all the 4.0L engines).
Call FORD and they deny any knowledge, say won't flash pcm as tsb states, nor will they reprogram tcm as tsb states. I guess your smart people left when Mercury was disbanded...
