Question about 1998 Ford Ranger SuperCab
Change the thermostat on ford ranger 2.5L
If the radiator is filled to the top with coolant and the engine is run without the radiator cap in place, the coolant will expand and spill over as the engine warms up.
When replacing the thermostat, also replace the gasket that seals the thermostat in place and is positioned between the water outlet casting and the engine block.
Generally, these gaskets are made of a composition fiber material and are die-cut to match the thermostat opening and mounting bolt configuration of the water outlet. Thermostat gaskets generally come with or without an adhesive backing. The adhesive backing of gaskets holds the thermostat securely centered in the mounting flange, leaving your both hands free to align and bolt the thermostat securely in place.

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.
