2000 ford taurus thermostat replacement

SOURCE: Replace thermostat in 2000 ford ranger

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

Follow the top radiator hose to the engine,the thermostat is behind the housing where the hose is connected to.

If it's the 3.0L Vulcan Engine (OHV), the thermostat is on the driver's side of the vehicle. Follow the upper radiator hose back to a metal area with three 10mm bolts. This is the thermostat housing. Undo the bolts, and there's the thermostat. Mark the back of it with the old thermostat in it (if you get one with a jiggle valve, it'll make it easier to put the new one in because the jiggle valve needs to be on top). The thermostat and housing aren't perfectly round, so you'll have to play with it a little to get it to line up. Make sure to change the gasket. The spring side of the thermostat goes into the engine.

The water pump is in the serpentine assembly. It's the larger pulley located toward the firewall. It'll be easiest to remove the water pump if you also remove the coolant recovery tank. The water pump pulley has four 1/2" bolts that you need to take out WITH THE BELT STILL ATTACHED. I can't stress this enough. The belt will keep the pulley in place so that you can remove the bolts. Take the pulley off, then the belt. Remove the heater hose at the top and the radiator hose at the bottom. There are 12 bolts of two diameters (1/2" and 10mm if I'm not mistaken). Tap the heater hose lightly with a soft-faced mallet to break the seal with the gasket. Trash the old gasket. Replace gasket (you can also line the mating surface of the water pump with RTV Sealant, put the new gasket on the new pump, and line the other side of gasket with a second coat of RTV sealant if you want a really good seal). Install the water pump and torque to manufacturer's specs. Attach the pulley to the water pump hand tight and put the belt back on. Tighten the pulley bolts. Put the coolant recovery tank back in place. Fill with coolant, start engine, bleed and check for leaks.

To bleed cooling system: Idle the engine until the thermostat opens (you'll be able to tell bacause the upper radiator hose will be uber hot and you'll feel coolant running through this hose). Squeeze all hoses in the system that you can reach, but don't burn yourself. Stop the engine and let it cool. Open the radiator cap and squeeze the COLD upper radiator hose. You'll see some bubbles in your recovery tank. You might have to monitor your coolant level for a couple of days while the final bits of air are purged through your radiator cap (that's why it's pressurized).

Hope this helps. It's not hard, but it took me quite awhile.

If it's only happening while sitting at a stop light and idling, the problem is probably in the cooling fans. Turn your A/C on high and pop the hood. Check your cooling fans to see if they're running. If they aren't running, it's the fan relay. In my 99 Taurus, the high speed fan relay is located in a slim black box next to the battery, it's the large square relay right up front. Use a known working relay of the same size and pop it into this relay. If the fans turn on, there's your problem. Replace the relay. Try the same with the A/C on low, but this relay is in the power distribution box (number 31). The 2002 may have a CCRM (Constant Control Relay Module). The CCRM is an expensive part (over $100.00). You'll be able to tell because the CCRM is a very large box that is mounted next to the battery and contains relays that are not replacable. It'll have a part number followed by a large letter/number. You'll need this part number and large letter/number to order the new.

sounds like the controller went bad use temp checker see what your temp is at inlet of heater core from hose
