ranger 4.0 head
« on: October 28, 2011, 08:39:06 PM »
Gaskets, Im thinking I need to replace them the coolant has been slowly disappearing but no leaks I can see. The oil looks fine(on dipstick) but there was a little spot of milk under the oil cap, would like to replace before it gets worse. Is there a decent manual to buy or do I need to find a factory service manual? Or and links or forums that can help with disassemble diagrams and mainly all the torque specs.

They aren't too bad. Check and make sure the vakves are sealing good. Some 4.0's had issues. Wouldn't hurt to get a book.

Thanks, it didnt look too bad I'll prob get a gasket set. Do you know if I need to remove the rockers or just pull the head then put it back on?

What you describe sounds like the results of crankcase condensation. Don't go fixing a problem that isn't there.

Do a cooling pressure test, and see where it's leaking.


If it's an OHV 4.0, head gaskets are easy. Similar to the 3.0L. You'll need a head gasket set (comes with every gasket needed), as well as TTY headbolts. Make sure to torque them correctly! I highly recommend a torque angle gauge.

If it's an OHC 4.0, you have to pull the engine to pull the heads. One of the camshaft chains is in the front, and the other is in the back. To get access to the rear one you gotta pull the engine. You *MAY* be able to do the job by unbolting the cam gear and tying the chain out of the way, but be sure not to drop the chain into the crankcase!

I'm pretty sure his is ohv. If its ohc, I recommend scrapping it.

Yeah its got a cam in block, I looked today at the coolant level with about 300 more miles than the last time I had to top it off and its at the same hot level as when I filled it a week ago. Hopefully ill be able to do the leakdown test this weekend, plan on doing a compression check while im at it.

If its not a bad leak, put some black pepper in it and ride on.

Have you pressure checked the radiator cap?

Didnt want to make a new topic but are all ford ranger bolt patters the same? Looking for the cheapest set of wheels to mount snow tires for the winter.

just changed the oil last night almost 3000 miles on the dot and it just looked like dirty oil no milk solution, need to do a compression check and plug check. If its burning coolant slowly I'll wait to hopefully spring to fix it, getting cold here soon  :'(

5 x 4 1/2" bolt pattern is used on all Rangers. Same as some F-150s, Dodge trucks, Jeeps. That is the "small" truck bolt pattern. The "big" pattern is 5 x 5 1/2", used on Fords and Dodges as well.

For example, my '05 Ranger has a 5 x 4 1/2" bolt pattern, but my '87 Dodge Ram has a 5 x 5 1/2" bolt pattern. Both are 4x4.

You'll find the smaller bolt pattern on base 1/2 ton Ford and Dodge trucks, typically 2WD models. I know for Dodges, the D-150s had the small pattern, whereas the W-150s have the big pattern.

This information is for old trucks, talking 1980's here. New stuff (2000's) may have metric bolt patterns, I dunno.
