I have a 1993 Dodge Caravan 3.0 Engine V6. I have been told It needs a water pump. I checked the hoses and clamps. I filled the radiator and on the left side driver's side it just kept pouring out behind the oil pan. Is that where the water pump is located? Unemployed in flippin Minneapolis. No honest mechanics. thanks Kathy

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

If it over heated before the thermostat, replace the radiator cap. Make sure the coolant (recommend just water until this is fixed) is full. When disconnecting the upper hose you lose all the coolant from the engine and about 1/3 of the coolant in the radiator. If you only full the radiator you don't have enough water. The new remonstrate needs to open for you to get enough water. In short- take radiator cap off. Start the engine. Fill radiator. Watch level for 5min, filling as needed.

drain the radiator, there is a petcock on the side/bottom it is plastic tee-handled shaped. then remove the two hose clamps one on the radiator the other on the engine( best with a socket mine are 5/16 inch). Hope this helps Tim.
Note: putting on ramps or jacking up and using approved jack stands gives plenty of workspace

the 1993 caravan had two engines offered a 2.5L 4cylinder and a 3.3L v6........on the 2.5L the thermostat is located on the front of the cylinder head were the top radiator hose attach's.
remove the top hose were it attach's to the thermostat housing and the remove the thermostat housing and lift out the thermostat and replace with the new one making sure the spring on the thermostat is facing the engine replace the thermostat housing and top radiator hose and remove the bleeder screw from the top of the thermostat housing and fill radiator with new antifreeze. when you see antifreeze coming out the bleeder hole replace the bleeder screw.

The 3.3L v6 also has the thermostat at the front of the cylinder head were the top radiator hose attach's the thermostat housing the procher is the same except for bleeding the radiator, to bleed the cooling system remove the coolant temp. sensor it is located just below the thermostat housing and fill radiator with new antifreeze until the antifreeze starts coming out the coolent tempt sensor hole them reinstall the sensor and top of radiator.........GOOD LUCK

check electric fan then check thermastat

replace? disconnect the negative battery cable from the battery, remove the serpentine belt, drain the radiator, remove the upper radiator hose to let the coolant drain from the engine, remove the hoses on the pump, remove the bolts holding the water pump on (if you're not sure which one, look at the belt diagram in the engine compartment on the passenger side. keep in mind, some coolant will still be in there), remove the pump (may need to knock it loose. do not use a screwdriver to pry it off. this will damage the metal and will not make a proper seal), gently remove all of the leftover seal from the engine, replace the seal and the pump, hand tighten all of the screws, then tighten them down, replace the hoses, fill the radiator with a 50/50 mixture of antifreeze and water, reconnect the battery, start it up. top off the radiator if necessary. put some extra in the overflow tank.

I hope this helps. The numbering is incorrect in the sequence but the instructions are correct.

Replace the bad radiator hose first.  Second- get you special formulated anti-freeze dye from the auto store and pour it into the radiator.  Third- make sure you got all the air pockets out of your system, cause the coolant system won't work with air pockets in it.  Fourth- Check for leaks by looking for the colored dye.  If it's not the radiator hose, then could possibly be a pin hole in your radiator.  Would suggest replacing all the radiator hoses at the same time while you got the coolant system disconnected, cause you don't want to have to come back and replace another hose in a few months.

You have to get the system pressure tested. Any decent mechanic probably won't charge for that because it takes but five mins. If you dont see any leaks it could be an internal leak, not good, so cross your fingers.

1. Disconnect the negative battery cable.
2. Place a drain pan under the radiator drain and drain the cooling system to just below the thermostat level. Close the drain.
3. Remove the upper radiator hose from the thermostat housing, then remove the housing.
4. Remove the thermostat and discard the gasket. Thermostat installation detail—3.0L engine Thermostat installation detail—3.3L and 3.8L engines

To install:

1. Clean the housing mating surfaces.
2. Dip the new gasket in clean water and place it on the water box surface.
3. Center the thermostat on the gasket, in the water box. Remove the radiator hose from the waterneck by loosening the hose clamp . . . . . . then loosen and remove the waterneck housing retaining bolts
4. Make certain the bolt threads are clean. Threaded bolt holes exposed to coolant are subject to corrosion and should be cleaned with a small wire brush or correct size thread-cutting tap. Install the housing, making sure the thermostat is still in the recess, and tighten the retaining bolts to 105 inch lbs. (12 Nm) for 3.0L engine or to 21 ft. lbs. (28 Nm) for 3.3L and 3.8L engines. Reconnect the upper radiator hose and tighten the hose clamp.
5. Connect the negative battery cable.
6. Fill and bleed the engine cooling system with a clean 50/50 mixture of ethylene glycol antifreeze and water. Lift the waterneck housing off of the lower intake manifold, then . . . . . . remove the thermostat out of its mounting flange
7. Make sure the radiator is full and start the vehicle
