I have a 99 2.5 with the smaller valve stem, anyone know the actual part number for a new one? After 6 miserable hours of uncomfortably laying on top of my engine like a beached whale and ripping of all the parts for the 4th time in the past month, successfully managed 15 valve locks (barely) and of course all the way in the back on the last damn spring, the spring tool decided it didn’t wanna do it anymore and snapped right down the middle sending my lock into the unknown abyss. I spent another solid 40 minutes checking absolutely everywhere from the top of my tranny to across the shop like a crackhead looking for a rock the he lost in his carpet. If anyone’s got the number for a single lock please let me know before I pour gasoline on my self and this truck and hop in and smoke a cigarette

 

well I guess If you got the PN still reply for anyone in the future looking for it but I found the damn lock while working today halfway across the shop in the middle of the floor

 

This is out of a 2000 Ranger shop manual. I'm pretty sure 98-2000 used the same 2.5L.
I'm glad to hear you found your part on the garage floor, but I figured I'd post this just for future reference.

 

does your manual state the number for that tool? I’d be interested in buying that for future work.

 

Here ya go.
The tool may or may not be available for sale, or the part number or tool may have been changed since 2000.
