the open pipe that you took the hose off of is the thermostat housing, you will need to remove this to reveal the thermostat, make sure you use a new gasket with sealant when reinstalling thermostat housing to prevent leaks and dont over tighten the bolts,run both bolts down as far as you can before final tightning

SOURCE: 98 ford ranger 4 cylinder.
Just did this today on my 2000 4 cyl. It was a pain.
First off drain the radiator. There is a piece that sticks out at the bottom on the radiator on the drivers side. Put a large container under it and unscrew the white-ish plastic bolt to release the fluid. Make sure the radiator cap is opened to let it drain quicker. Then remove the top hose. The thermostat housing is at the end of the radiator hose on the engine. There is a bolt on the upper right, right up against the belt shroud for the camshaft. There is one more under the housing to the left. You pretty much have to feel for it. There is not much space to work with so I removed the fan (4 bolts) wiggle it off. To remove the fan you also have to remove the shroud to get it off. No problem just two bolts. This should give you plenty of room to work with. Then remove the housing and exchange parts. Replace the gasket (its a small rubber o ring. Mine looked fine so I left it, but I did put a bead of silicon around it just in case. Reverse the steps and add fluid back to the system.

I recommend flushing the radiator thoroughly if not done recently. there seems to be some sort of blockage in the radiator at this time. if you get lots of metal fragments that are flushed out during this flush, i will then recommend a rebuild on the radiator or replacement of the radiator. make sure the cooling fans are cycling on time as well.

If you are just replacing the bulb, then it is accessable from the engine compartment with minimal effort. You may have to remove the battery or any other movable object right behind the headlight, but in a lot of cases, even that is not necessessary. Look at the rear of your headlights (through the engine compartment) and on the far side twards the fender (where the turn signal should be) there will be a wire running into it. At the point of where the wire meets the casing there should be some type of clip. You just rotate the clip about 1/4 turn or less and it will release the clip with bulb attached. Then push, twist, and release on the bulb to get it out of it's socket. Installation is reverse of removal.l

Testimonial: "Yours is the only helpful advice so far. Hope the actual work is as easy as you make it seem. Thanks. tikit72"
The valve covers installed on the 3.0L engine incorporate integral
(built in) gaskets which should last the life of the vehicle.
Replacement gaskets are available if required.
