Keep it simple, keep it running, have fun
Just Checking in here, I have owned my 99 Ranger XLT (4.0 OHV) for a while now. No huge plans, just want to keep it running and looking good as long as possible. Planning on pulling the bed off and doing some rust clean up this summer. Already pulled the vacuum system 4x4 off and installed some manual lockers.
Need some pointers to remove the intake manifold and do the gaskets. Probably already a write up for it but I haven’t search around yet.
-Thanks ahead of time,
Chris
Welcome to the forum
Nice looking Ranger
I have a 1994 4.0l with 400k
Watch for overheating and shut down engine right away, 4.0l heads have a weak spot between valve seats, if overheated a head will crack, so don't try to make it home, let it cool off and then limp home in short hops.
Heads are fine if not overheated.
The 4.0l lower intake bolts like to unscrew themselves, and they only have like 12ft/lb torque, so use locktite on those bolts when reinstalling gasket
Also the lower intake is aluminum, and its bolted to cast iron heads, so aluminum can get eaten away if you don't keep coolant PH high
Always swap around heater hoses at the firewall, every year or so, reverse direction of flow in heater core will make it last longer, apples to any vehicle really
1999 Ranger will run 55psi fuel pressure, 1997 and earlier Rangers ran 30psi
Rangers used 2 different 4 liter engines, 1990-2000 4.0l OHV and the 2001-2011 4.0l SOHC
1999 Ranger was also the first year for 2 wire Cam sensors and PATS(passive anti-theft system)
PATS requires a PATS key in the ignition that sends a unique number to the PATS module(above glove box), that number is compared to 3 or 4 numbers programmed into it at the factory, the keys it came with new
If match is found engine will start, if no match then no start, it disables fuel pump and fuel injectors, so no "work around"
You do want to have an extra/spare working PATS key
Keys can be programmed(added to PATS module) by most locksmiths
Or Working PATS key can be Cloned, less expensive option, so same unique number from working PATS key is cloned on to a Blank PATS key, then cut to match lock like any key
