The thermostat on V6 engines is under the thermostat housing at the engine side of the top radiator hose. The thermostat on V8 models is found by tracing the bottom radiator hose back to the thermostat housing on the engine. The housing, thermostat, and O-ring on the V8 models is built as an assembly and will have to be replaced as such.

Hello. Here a non-photo diagram. Hope this helps!!!

The thermostat is located on the side of the water pump, the water pump is located just above the a/c compressor, the thermostat is fed coolant from the radiators lower radiator hose.
Thermostat :
1. drain coolant and tighten drain plug ( easier method : remove radiator cap, get big drain pan, place drain pan under lower radiator hose to radiator connection, remove clamp, slowly remove hose, allow coolant to drain into pan, now is a good time to remove radiator hose and clamp from thermostat housing )
2. remove thermostat cover / cap ( easiest to get at this when front of car is supported by jack stands and right hand side lower cover is removed ).
3. thermostat cap is held on by 3 bolts / remove thermostat.

You will notice that the thermostat's air bleed hole is pointing up and lines up with notch in water pump housing,,

ATTENTION :failure to install new thermostat in the correct location will cause engine to overheat.

1. install new thermostat to water pump, make sure air bleed hole lines up with notch, install and tighten bolts, install a new lower radiator hose, fill cooling system.

thermostat # 17670-77E00
lower radiator hose #17854-65G20
hose clamp #09401-36403
upper radiator hose # 17852-65G20

The engine got hot could it be the thermostat and where is it located also the water pump


Could be thermostat, follow the upper radiator hose from radiator to engine, where it hooks up at engine end, is where thermostat is at, remove small bolts at housing where hose clamps to, under that housing is where thermostat is at.Water pump, follow lower radiator hose from radiator to engine, where it hook up to, is where water pump is at.

If you were to take the upper radiator hose off the engine, and look into the resultant hole, you would see the thermostat.

The thermostat on all cars blocks water leaving the engine and going to the radiator, until the thermostat warms up enough to open.

While the thermostat is closed, water circulates through the heater hose, straight back to the inlet of the water pump. This circulation prevents hot spots, distributing the heat evenly to warm the engine up, and also brings that warmed water to the thermostat.

When the t-stat gets hot enough to open, water leaves the engine instead of circulating through it, and that allows cool(ed) water to flow from the radiator through the bottom hose to replace the water that left through the upper hose and t-stat.

The stub that the upper hose attaches to on the engine should be part of a small housing that is bolted to the engine. Removing that housing is how you remove the t-stat.

2000 chevy silverado normal operating temp 210 , recently temp rises to 250. water pumps no leaks therm. appears OK .


With the truck running at operating temperature, squeeze your upper radiator hose. You may have to check it a couple times allowing time for your thermostat to open. Are you able to compress the hose a little when you squeeze it or does it remain stiff/solid? Your thermostat may be stuck open or even stuck closed.

Need to replace thermostat 2000 taurus


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.
