Recently changed Plugs in my 2008 EdgeAWDSEL V6~3.5L~DOHC from stock Platinum FordMotorCraft# ayfs22fm\sp411 to Iridium AutoLite# xp5364 with good results, running 10kMiles since. Cleaned+OhmChecked the Coils while I was there. If no Transmission Drain+Refill in the last 33kMiles, consider that. Awhile back switched ATF from stock MerconV Fluid to AmsOil# SSMV with good results; shifts smooth+quick.

After reviewing OwnersManual spec & a little online reading+research, these 3 Coolants seem best suited for my 2008 V6~3.5L~DOHC

Drain\Suction old GearOil from the PTU. ReFill with 16oz~18oz of AmsOilSevereGear# 75w140 or SAE250. It may be too late to save it, but can try this as last resort. These PTUs are simply mounted too close to exhaust & cats, which cooks the GearOil. Best to change PTU GearOil every 5k~10kMiles along with engine Oil+Filter.

Ok yes , ATF level is good, checked it daily during the trip. Will try setting new TempSwitch down another 10~15f & see what effect that has on Transmisson operating temp. Using AmsOil SevereGear 75w140 & 75w90 front axle PTU & rear axle DIF respectively. Now servicing PTU every 6months along with Engine Oil+Filter; rear DIF is getting only 33kMile GearOil changes as that used oil comes out appearing new. PS: yes when I had the Radiator & TransmissionCoolers out, I did wash AC Condensor, picked out the road kill & strainghtened any bent fins. Getting the Condensor coil seperated from the radiator was a job, they were not designed to be installed\removed seperately.

2008 EdgeAWDSEL V6~3.4L~DOHC Roughly 147k Miles before above maintenance items & road trip; just rolled 150k Miles. Radiator fans now respond as they had before; ~ normally OFF when idling with AirCon OFF. ~ normally LoSpeed when idling with AirCon ON. The 2 new 8inch TransmissionCooler fans (front mounted pushers) operate independent of RadiatorFans (rear mounted suction), on their own 20aRated Adjustable TempSwtch set to come on at roughly 195f via a TempBulb strapped to the hot side tubing. This Switch has a 5~6f deadband. Highest ambient temp seen during trip was ~90f in Nebraska; typically has been 70~80f. So this trip has not been a test in >95f summer heat. Prior to above maintenance items both Engine & Transmission temps typically ran 6~8f hotter. So I feel I've done some good, but would like another 5-10f cooler if possible. Is it possible using ForScan, to adjust the Radiator Fans to go HiSpeed earlier & stay on longer?

2021Sep29 Update on above 2008 Edge Maintenance Items, after multistate NY~PA~OH~MI~WI~MN~SD~NE~CO road trip: ~ Mileage peaked at 21.9mpg, typically 21.6mpg running Regular 85~87octane, better at lower altitudes ~ Engine Temp peaked at 205f, typically 195~201f at highway speed, higher while accelerating\climbing ~ Transmission Temp peaked at 208f, typically 190~199f at highway speed, lower while idling\parked Ran well with good power. 0~65mph freeway ramp acceleration, & 65~90mph passing acceleration, but ~ would like Engine & Transmission temps 5~10f lower; considering new Radiator & TransCooler. ~ will need new tires soon.

Have someone pull release handle under dash, while you're lifting front edge of the hood. Then liberally apply silicone spray lube to the latch before closing.

^^^^Ditto on changing+maintaining all fluids. Especially the PTU GearOil, assuming it's AWD? Consider installing a PTU Drain+Fill per the threads below, so it can be easily+frequently serviced. https://www.fordedgeforum.com/topic/23396-ptu-drain-plug-drill-and-tap/?do=findComment&comment=219556 https://www.ford-trucks.com/forums/1665303-2007-2011-ford-edgeawd-ptu-mod-for-easy-oilchange.html Again welcome to the herd!

Welcome to the herd! Looks like same SilverMetalic color as my 2008 EdgeAWDSEL. If yours is AWD, change the PTU GearOil as soon as possible; maybe even Drill+Tap the PTU & install a drain per this thread https://www.fordedgeforum.com/topic/23396-ptu-drill-and-tap/?do=findComment&comment=219556 Again welcome!

@Ramon You've got a problem with a 2011 EdgeSEL; you've posted this thread in the 2008 Edge forum section? Might get a better response by moving it to the 2011 Edge forum section.

Best thing I've done for this Edge is to make PTU GearOil changes easy (now done with routine Engine Oil+Filter changes) by installing a PTU drain valve, fill hose, & vent hose up to an UnderHood Fill+Vent+FilterCan per these threads: https://www.fordedgeforum.com/topic/23396-ptu-drain-plug-drill-and-tap/?do=findComment&comment=219556 https://www.ford-trucks.com/forums/1665303-2007-2011-ford-edgeawd-ptu-mod-for-easy-oilchange.html

Also now gathering parts to replace plugs & other items on a 2008 EdgeAWDSEL V6~3.5L~DOHC. Putting in new AutoLite xp5364 Iridium Plugs. While there, will also: ~ Clean+OhmCheck Coils ~ Replace PCVValve ~ Replace All 4 OxygenSensors ~ Replace 5of6 Coolant Hoses+Clamps ~ Replace Coolant ThermoStat ~ Replace IntakeManifold Gaskets\ORings, Clean ThrottleBody+IntakeManifold ~ Drain+Flush+Replace Coolant ~ Replace Both Belts Some vids on replacing the plugs: https://www.youtube.com/watch?v=8GDZ3Fn5uUU https://www.youtube.com/watch?v=Yg7rmtKZ360 https://www.youtube.com/watch?v=QES9mgex8cw

Do simular thing here also, with both the 2001 ExSportTrac & 2008 EdgeAWD, handpump both Steering & Brake reservoirs down near empty & refresh with those respective new fluids, plus handpump ~1qt of fluid out of the Tranny DipStickTube & refresh that ATF, all along with the usual Engine Oil+Filter change, as part of the 6mth maintenance routine. Also have added doing the PTU GearOil drain+refresh every 6mths, since adding Fumoto DrainValve & OilCatchCan+Fill@FireWallUnderHood for that.

Wanted to thank ManiN for his thread entry, specificly how to remove the PTU VentCap, & BuckNewby for his vids on how to install a PTU Drain. These inspired the PTU mods on my 2008 EdgeAWD; details at: https://www.fordedgeforum.com/topic/23396-ptu-drill-and-tap/?do=findComment&comment=219556

I'd confirm what OilChange Tech said; best put Edge on jack stands then crawl under & inspect yourself. PTU=TransferCase could be venting GearOil out top & that's spilling down over the case & rear output shaft? How many miles on the vehicle & has the PTU GearOil ever been changed? Does your PTU have just a 1/2" FillBung, or does it also have a smaller DrainBung? If only a 1/2"FillBung, then recommend Drilling+Tapping the PTU case bottom & installing a Drain. Details on how to do this at https://www.fordedgeforum.com/topic/23396-ptu-drill-and-tap/?do=findComment&comment=219556

Posted this in AllWheelDrive\AWD section, but thought it's also appropriate in this thread on 2008 Ford Edge PTU issues. Thanks to Bucknewby plus several other videos & forum threads, while doing latest 3yr\33kMile Oil changes for the front PTU & rear Differential on my wifes 2008 Ford EdgeSELAWD, installed modifications noted+pictured below to ease servicing the PTU. ~ Drilled+Tapped PTU AluminumCase bottom; installed new 0i375\0m010ThreadDiameter DrainValve Fumoto#f124n. ~ Removed PTU top Vent JiggleCap+Rubber1Way (used 5/8"Socket+ScrewPick); reveals 3/8"HoseBarb; installed 3/8"ID Fuel\Oil Hose upto new OilCatchCan on FireWall. ~ Replaced PTU side FillPlug with 1/2"PipeThread~3/8"HoseBarbElbow; installed 3/8"ID Fuel\Oil Hose upto new OilCatchCan on FireWall. ~ Installed new OilCatchCan\Tank + VentFilter + 3/8"PipeThread~3/8"HoseBarbElbows2ea on FireWall upper lip, between FuseBox+Battery. The Filter+Strainer fittings inside the OilCatchCan are not required, thus were removed & not used. Now easy to drain Oil from PTU & refill at OilCatchCan top Plug: 1/2qt=16oz AmsOil#75w140.FullSyn + 2oz ATP#at205\ReSeal. Also wrapped ExhaustPipe under+near PTU with FiberGlassInsulation to help reduce it's operating temp. Considering trouble others have had & how black oil was, may do PTU Oil change with Engine Oil change every 6mths\5kMiles.
