Thanks for the reply. Any idea why the overdrive indicator blinks? Related to 4X4 switch code?

Hi all- A friend of mine has a '97 Expedition. He bought it a few months ago. Twice since he bought it, he notices that the overdrive light on the shift lever handle is blinking. Just driving down the highway. Then he pulls over to the side of the road. Shuts off the engine. Restarts it and...

No offense intended. My appologies. That's why I used quotation marks.Thanks for your replies. I appreciate it very much!

Owner of this vehicle traded it off. It's outa my hair! Thanks for your responses!

Working on a 2001 F150. Drained the rear diff to replace axle seals. Has the 9.5 inch ring gear with "positraction". The tag on the diff says to use 75w-140 synthetic fluid. My question is... do I need to add friction modifyer?

It turns out the owner of this vehicle had the engine rebuilt at an indie shop 15000 miles ago. The shop agreed to repair it for the owner for free! So I'm outta the loop thank goodness!Thank you all for your replies. I sincerely appreciate it!If you have any General Motors questions, feel...

Nope. No oil cooler. Lookin' more like a head gasket all the time!

I was just looking at alldata. Did not realize that the cooler is mounted by the oil filter. Haven't looked yet to see if it has one there. I will check it out. Thanks for the info!

Not sure what u mean by a filter inside the LF fender... I see only one set of cooler lines going to the radiator. I would suppose they are for the transmission.

No the oil doesn't appear milky. It's quite dark, 1 qt low and needs to be changed tho! The coolant in the jug that's under the layer of chocolate brown oil is nice and green.

I'm working on a 1999 Expedition with a 4.6 engine. There is about 1/4 inch layer of oil on top of the coolant in the surge tank. Can someone tell me where this most commonly comes from? Thank you!
