Before the replacement engine goes in...what should I do to it?

[joey_hv]

I have to change out my engine in my '98 explorer 4x4 4.0 SOHC
with a replacement that has 46k miles. Is there anything that I should do to the replacement engine before I put it in that can only be done while the engine is out?

haha I say make sure the plugs are brand new! It is a $%#@ trying to change them in a 4.0 SOHC!

Besides that though...I say just make sure it is looking good!

roger that!
i ran into the plug problem already...i just changed 4 of them and called it good:

The placement of the two plugs on the passenger side (not the front one) are SOOO annoying to replace. It took me an hour just on those two plugs with a ten inch extension and a swivel to get them replaced. By the way..if you are replacing plugs on a SOHC, a swivel and extension are INVALUABLE!!

GOODLUCK with the swap!

If you are doing it yourself...is there anyway you could post pics and make a how to thread about it???? I REALLY would love that!!

Plugs are easy to access if you remove the right front wheel well liner. Obviously much easier when the engine is out.

I'd also look into replacing/updating the cam chain parts. Cheap insurance that the engine will run a 100K without any mechanical issues.

Pressure wash the engine compartment so it's nice and clean.
