I had taken my van in to ford and for repairs for the P171 & P174. ford covers this service under teh 7 yr 70 miles waranty. luckly my va was onl at 64K so ford covered it.
What was done replace a/ repaired the some under teh oil (blk cover where the oil is pored into the engine. then took off th manifold cover (black top cover ) and replaced the soe parts with new parts. gray colo rings ( like a oil ring but flexable kind not a solid kind. bottom line is they fixed it and the van runs fantastic just lie new again with full 20 horses back to the engine. But now I have other mior isses such as ABS brake system how do I check and replace the part if need it and what is the part number and what is it called? also how do I fix the wires for the speckers. |
