New 2008 Edge Limited owner

Recommended Posts

Good looking 2008 Edge.  Have a 2008 EdgeSEL AWD here.

Be aware of these NotoriousFailureItems:

~ InternalChainDriven WaterPump in the transverse 3.5L\3.7L, best to change this out every 100kMiles before it leaks coolant into oil & destroys engine.

~ PowerTransferUnit\PTU in AWD models, best to Drill+Tap a drain, then renew 75w140 GearOil every 33kMiles; otherwise this PTU will fail.

As @DILLARD000 said, plus check SPARK PLUGS, need to be changed at 90k miles. If there's any question, change all fluids, brake, pwr steering, PTU, COOLANT and TRANSMISSION. (Caps are .out important).


Less important is the cabin air filter (behind glove box) and under seat filters (if you have heated/cooled seats. The filters in the 08 are actually filters. In late 09 and later these were changed to open grills).

Yep, SparkPlugs & OxSensors should be renewed every 10yrs\100kMiles or your MPGs+Performance+CatCons will suffer
