Do a pressure test on the cooling system.

My suspicion at this point is that you have a blown head gasket or cracked cylinder wall.

Maybe your radiator is clogged.

Hope this helps you....

Instructions

1. Prepare the Dodge Intrepid
   • 1 Lay out a drop cloth underneath the Dodge Intrepid to protect the floor from coolant spills. Designate an area to lay out each part alongside its bolts and connecting hoses and wires. Use a drop cloth here as well, some of the parts will have traces of grease and coolant.
     
   • 2 Disconnect the negative battery cable, using a screwdriver to unscrew the clamp that secures the cable to the negative (-) post. Pull the cable away from the battery post.
     
   • 3 Use a jack to elevate the Dodge Intrepid and jack stands to shore up the jack. Release the pressure in the radiator by removing the cap. Take out the drain plug located underneath the radiator. Catch the coolant in a resealable container
     
   • 4 Use a grease pencil to mark on the timing belt its position in each pulley before removal. This will save time when reinstalling. If needed, replace the timing belt and skip marking the old one.
     
   Remove the Damaged Pump
   • 5 Locate the water pump on the Dodge Intrepid. It's mounted on the front of the engine block and connected to the radiator and various other parts through a series of hoses. It's rotated by the timing belt. Study these parts, as you'll have to remove them.
     
   • 6 Disconnect or remove the parts in front of the water pump, using an adjustable wrench. In the most common Dodge Intrepid engine--the 2.7L--you'll find, in order: the upper radiator crossmember, fan module, accessory drive belts, crankshaft damper, timing cover, timing chain and guide wires.
     
   • 7 Unbolt the water pump from the engine block, using an adjustable wrench. You may have to use a chisel to gently break the seal between the mount and the pump. Discard both the pump and the bolts.
     
   • 8 Clean off the mounting area with a shop rag.
     
   Install the New Pump
   • 9 Inspect the new water pump to ensure it's identical to the old pump and free of any metal splinters or debris.
     
   • 10 Arrange the new water pump on the mount. You won't need sealant for the o-ring on a Dodge Intrepid. Hold the water pump and o-ring in place as you secure it with the new bolts. Tighten them with a torque wrench to 105 inch pounds torque in any order.
     
   • 11 Install the timing belt and wires, using the grease pencil marks to guide you in installation. Install the rest of the parts in the order removed. The camshaft must be reconnected with a torque wrench at 125 foot pounds torque.
     
   • 12 Replace the radiator's drain plug and refill the radiator with the amount and type of coolant specified in your owner's manual. Release the jack and jack stands.
     
   • 13 Attach the negative battery cable to the post and tighten the screw on the clamp. Crank the Dodge Intrepid's engine and check for leaks. Then, close the hood.

Turn crankshaft so #1 cylinder is at TDC then loosen timing belt tensioner lock bolt and pry tensioner away to loosen belt retighten tensioner lock bolt, remove and inspect timing belt as now is the time to replace bad or worn belt remove the water pump bolts and then same the coolant pump is the plate with the timing belt tensioner and idler pulley and a cogged gear at lower right. clean mating surfaces install in reverse order tighten coolant pump bolts to 16 ft-lb and tihgten tensioner bolt to 32 ft-lb coolant capacity about 7 quarts. be ecofreindly dispose of coolant according to local laws

Then replace the thermostat, because if on lower hose not hot and on upper hose scalding hot = antifreeze flow blocked by the thermostat wich remains closed!!!

Prepare the Dodge Intrepid
1. Step 1 Lay out a drop cloth underneath the Dodge Intrepid to protect the floor from coolant spills. Designate an area to lay out each part alongside its bolts and connecting hoses and wires. Use a drop cloth here as well, some of the parts will have traces of grease and coolant.
   
2. Step 2 Disconnect the negative battery cable, using a screwdriver to unscrew the clamp that secures the cable to the negative (-) post. Pull the cable away from the battery post.

remove belt drain radiator remove fan shroud remove fan /pulley remove top hose on water pump and lower hose un bolt water pump remember mark bolts because lower longer need sealant due to they go into water jacket remove and clean around both water openings before setting in place hook up upper bypass hose easier to hook up before install--replace and rebolt everything

This a dificult and time consuming project. Suggest you purchase you a repair manual which gives you diagrams and detailed instructions for this type of repair. Difficult to explain procudure in writing.

check first if you are loosing water or cooling fluids on your radiator. There may be a leak or the radiator cap may no longer prevent the steam from escaping. check the radiator fans if they are turning. You can check the fan if it is working by removing the temp sensor at the lower radiator hose. The fan should turn on by then.
