Coolant pouring from bottom most outter shell of engine underneath crankshaft, secondary belt is gone the one that pulls the water pump and air. What caused this and what the cost might be to fix. Thankz

Re: massive coolant loss
The water pump is located inside the timing cover depending on engine size and is more than likely the culprit. You will need to replace all the belts,pump and timing belt. This requires a special puller for the crank pulley so if you don't have it you will more than likely not get it apart.Let me know if this helps or you need more info. Thanks....Dan

For all dodge minivans 94 to 2001 (and others) with 3.0 ltr V-6. You're
driving on the freeway your temp gauge starting to go up. You get off
the freeway. when the engine is cooled down you discover that the
coolant in gone. You refill the radiator and look for a leak but can't
find one. You check the oil but its not foamy, so no coolant there. If
all seems to be operating normally, check under the vehicle when the
engine is warmed up. There may be a slight coolant leak on the
passenger side near the front tire .When the water pump on these
engines typically coolant will leak out of the pump thru a "weep hole"
located at the bottom of the pump. Most of the loss occurs while
driving so your only indication may be that small drip of coolant. The
water pump is powered by the camshaft timing belt and is located under
the timing belt cover and can not be seen, however any coolant leak, no
matter how small, in the area just to the rear of the crankshaft pulley
is almost surely a failed water pump and must be addressed immediately

This phenomenon is called blow by. This usually happens when the engine compression escapes through the worn out piston rings due to the severely scratched cylinder wall. It also happens after the engine becomes severely overheated due to the loss of coolant or the car is driven with ruptured element air cleaner for longer period of time or due to the aging factor.
In this case the engine requires complete overhaul. It includes the replacement of the following parts to help enable the engine to perform satisfactorily as long as for many years without any problem.
The dire requirement here is to maintain the oil clearances of various parts during the machining process to ensure the reliability and dependability of the engine.
Engine parts to be replaced with original:
- Engine valves.
- Valve guides,
- Piston set (oversize).
- Ring set (oversize).
- Main and big end bearing shell set (Oversize).
- Crankshaft thrust (oversize).
- Timing belt and bearing set.
- Gasket set complete kit.
- Oil filter.
- Element air cleaner.
- Engine oil.
- Silicone RTV Grey.
- Radiator coolant.
- New valves and guides fitting and valve seat redressing.
- Valve clearance adjustment.
- Cylinder re-boring and honing.
- Crankshaft grinding, main and big end bearings fitting, and main line checking/ correction.
- Connecting rod alignment.
- Radiator cleaning and cooling system inspection.
Hope that works.
Thanks for visiting Fixya.
Maybe. The broken belt would not cause the leaking coolant, but it could have damaged some valves when it broke.
It may cost more to fix the engine than to replace it. You would need an actual estimate for repairs to know for sure.
It has popped the freeze plugs out and you won't know the extent of the damage it has made till you replace the freeze plugs. You never i mean never pour water into a vehicle around time for freezing weather
Does it have a 2.5L? If so this particular engine is notorious for bad head gaskets. The after market ones are great but the originals are ****. In a shop this may cost you around a $1000, they fixed the problem in later years. Is there white smoke coming from tail pipe? A milky substance on engine oil dipstick? Lack of power? losing coolant and not knowing where its going (none on ground)? It is the head gasket!
If I am wrong and it is the water pump the job is a lot easier. I apologize but I am going to explain this to you like you are 3 years old , just in case you are not mechanically inclined.
Unlike old older cars the water pump is driven by the timing belt. The timing belt is located under the timing cover in the front of the car. When you removed the thermostat the thermostat came out of the water pump, literally.
1. First you need to remove all the drive belts off the alternator, power steering, etc.
2. Then you remove the crankshaft pully (this is in the pulley in the center of the engine it is surrounded by a black cover behind it). You will have to stick a screwdriver in the flywheel (there is a access hole in between transmission and engine below the throttle body (like a carburetor) ) to stop the engine from spinning while loosing the bolt on the crankshaft (it is on tight).
3. After that you have exposed the timing cover it is maybe in 2-3 pieces (depending on the engine) remove the bolts of the timing belt cover (I believe they are 10mm) The timing cover should slide right off and the timing belt underneath is revealed.
4. Looking at the timing belt configuration you will see several pulleys. The ones to the far left and to the far right are the cam shafts (do not move these it will throw off the timing and make the car run like ****) The center is the crankshaft and there are 2 idler pulleys (they tighten the belt down). Finally on the right in between the camshaft and crankshaft is the water pump (you will see the lower radiator hose going into the bottom.
5. Drain the coolant from the radiator ( should be a plug on the bottom right (while looking at engine)
6. Once it is all drained you can then remove the lower radiator hose (where the thermostat is).
7. remove the 2 bolts holding the thermostat housing (what the radiator hose connects too) on the bottom
8. The thermostat will fall out
9. Mark the place of the timing belt with marker on camshaft pulley (on both sides), belt, and on engine. (this ensures that it goes back on exactly the way it came off. Remove the water pump bolts and remove the water pump (it may stick a little, tap side lightly to break seal) while removing water pump the timing belt will loosen just leave it (when you put new water pump back in it will tighten back up (do not remove the timing belt!!)
10. Scrap the old gasket off and apply new gasket, apply new water pump. Torque the bolts to 20 ft pounds. In a zig zag pattern (this ensures that it goes on evenly and gets a proper seal) Make sure that the timing belt marks you made all line up also. (If timing belt looks old and is fraying it may need replaced email me to get details on how replace it at email@example.com
11. Put thermostat back in and thermostat housing (maybe easier from underneath. Put radiator hose back and tighten clamp.
12.. Put timing belt covers back on, crankshaft (torque this to 90ft pounds) be sure to remove the screwdriver from flywheel, and put drive belts back on.
13. Put coolant back in the radaitor (be sure the drain is closed up first)
14. Run engine for about 15 mins coolant may go down replenish as necessary (getting air out of system).
Hope this helps, please email me if you have questions. firstname.lastname@example.org
If you have a 2.7 engine, your water pump is in need of replacement bad. It's located behind the timing cover and is turned by the timing chain. When the water pump goes out, coolant pours out in the inside of the timing belt and into the oil pan leaving the same water in the oil look as if you had a blown headgasket.
