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.

1989 ford ranger thermostat replacment


First remove the bolts from the thermostat housing which is connected to the top hose on the radiator. Grasp the thermostat with either hand or pliers and remove, next use a scraper or wire brush to clean the surface on the engine and on the thermostat housing. Both surfaces need to be clear of debris, you should be able run finger accross surface and feel no bumps(it should be smooth). Then place the thermostat back in same orientation as old one came out and place gasket on thermostat housing (pay attention some gaskets have paper covering self adhesive). Place bolts through housing and gasket, thread the bolts into engine until finger tight then use socket to tighten snug but do not force tight.

Replace thermostat on 99 ford ranger with 2.5 engine


The upper radiator hose is connected between the upper radiator and the thermostat housing. Drain the coolant then remove the upper radiator hose from the thermostat housing, replace if necessary. Remove anything blocking access to the two bolts holding the housing to the engine such as the belt cover. Pay attention to the orientation of the thermostat so you install the new one correctly. If the housing is corroded or pitted you have have to replace it or suffer leaks. Push a rag into the engine opening now exposed and clean the contact surface well so it won't leak later. Installation is the reverse of the process.

Where is the Thermostat for 1999 ford contour located


On the 4 cylinder 2.0 L the thermostat is located where the upper Radiator hose and the recovery tank hose connect to the housing on the block. Disconnect the Neg (-) (Black) terminal. Drain and recycle the coolant, remove the air intake resonator, the recovery and upper hoses. remove the three bolts to the housing, remove the thermostat and )-ring (important, replace the O ring with your new thermostat. re assemble as you have taken apart. tork the bolts to 71-97 inch lbs on the 6 cylinder 2.5 L the process is similar, except there are only two bolts on the housing, tork the bolts after you have installed the new one to 15-22 ft lbs. I hope this solves your issue, thanks

How do you change the thermostat on a 98 ford ranger 2.5L


CAUTION 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.

  • Drain some coolant into a clean container until the coolant level is below the thermostat housing.
  • Remove the upper radiator hose connection from the thermostat housing.
  • Loosen the housing bolts and remove the housing.
  • Remove the gasket and scrape it carefully from the surface of the housing and the mounting surface on the engine. If the gasket remains on either of the surfaces, there will probably bea coolant leak after reassembly. Some engines use a rubber O-ring to seal a thermostat housing.
  • Compare the size of the thermostat to the old one. They are of different sizes, types, and temperature ratings.
  • The temperature rating is stamped on the sensing bulb on the bottom of the thermostat. The temperature bulb faces the block.
  • When replacing a thermostat, be sure that the thermostat fits into the groove in the block or outlet housing. If the thermostat is installed upside down, the engine will overheat.
  • Install the gasket.
  • Reinstall the thermostat housing. Refill the system and run the engine or pressure test to check for leaks.
  • When the engine has reached operating temperature make sure the thermostat opens.
  • You should be able to see coolant circulating within the radiator.
  • Another way of checking thermostat operation is to feel the top of the radiator hose or use a thermometer or multimeter with a temperature probe to confirm that the coolant is warming up.
  • If the engine is overheating, but the top hose is still cool to the touch, the thermostat is stuck closed and must be replaced.


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.
  • Remove the thermostat housing.
  • Remove the gasket and scrape it carefully from the surface of the housing and the mounting surface on the engine. If any gasket remains on either of the surfaces, there will probably be a coolant leak after reassembly.
  • Some engines use a rubber O-ring to seal a thermostat housing.
  • Install the gasket.
Hopefully this is helpfully
