154000 miles great condition automatic 4.6 liter what should I look for and what sevice should be done. Thanks!

 

When I get one that has over 60K miles on it,the first thing I do is change EVERY fluid. ALL of them. You don't know when the previous owner changed them last,nor the actual condition of the fluids,and then you have a baseline of when your service scheduling should go from. I also change EVERY filter on the vehicle too,for the same reasons as above.
It might need a serpentine belt, spark plugs changed, and possibly upper/lower ball joints and u-joints if none of that has ever been changed.

Definantly change fluids and filters. To me these trucks are very reliable and shouldn't give you a whole lot of issues I have a 98 F150 with the 4.6L also but I have 237000 mi. on it and have had less problems than some new trucks. Good luck and remember if you do the spark plugs and wires use Motorcraft.

 

Thankyou!bbbbbbbb

 

Find out exactly WHEN your truck was made,,, on the models made in early 98' and before, with the 4.6L v6 engines, the lower intake gaskets (the gaskets that are between the block and the intake manifold), after years of use could leak coolant into the cylinder causing engine failure,,, check any and all paperwork that came with your truck to see if the gaskets have been replaced with upgraded ones,,
