Question about 1988 Dodge B350

1 Answer

Sudden severe Dodge 360 cooling-system problem

I have a sudden severe Dodge 360 cooling-system problem - 1989 B350. Suddenly the hose fitting for the ''engine side'' of the water-pump bypass hose began leaking profusely with no warning. Now I get about 1 mile per gallon of water into the radiator. I took off the ''bypass hose'' and there was no obvious defect in the hose, but I replaced it anyway. Naturally, the leak was unaffected.
4 NAPA folks can't tell me from memory if that fitting goes into the block or into the intake manifold or into the timing cover. There are so many hoses and shadows and glops of old blackened oil that I can't see clearly back in there - not even with a normal flashlight. The leak appears to be either from the base (threads?) of the large metal hose-fitting or from the corresponding threads of the block/intake-manifold/timing-cover itself.

Naturally I worry that an oversize pipe-fitting remover will simply crush or shear the old rusty fitting and leave an ugly fragile shattered stub sticking out of the engine.

Does you know where I can find a good diagram or photo for the front of the engine at this location in-between the water pump and the intake-manifold area?

Is it futile to remove the fitting when maybe the fitting is OK, but the threads of the block/intake/cover could be the culprit? Is there any way to remove a rusty fragile shattered stub from its tomb in the mounting threads in the engine - if that accident happens next?

Thanks in advance for all helpful ideas.

    I really suggest based on the complex issue here that u pay to use the live chat option or the pay question option, your choice, otherwise it is doubtful u will get much help in the free forum.. also u can buy a used factory service manual on ebay.

How do you put a water pump i a 1999 dodge durango 5.2 8cyc 4wd. if can step by step and a


First disconnectthe cable from negative terminal of the battery. drain the cooling system if the coolant is relatively new or in good condition, save it. remove the cooling fan and shroud. remove the drive belt and water pump pulley. loosen the clamps and detach the hoses from the water pump. if stuck try to twist to break seal. check hoses if bad replace. on v6 & v8 remove the water pump coolant return tube mounting bolt. Remove the bolts and detach the water pump from the engine. Note: the location of the various lengths and different types of bolts as you remove them. to ensure correct installation. on v8 models reach above the water pump with pilers to release the hose clamp on the bypass hose.clean the bolt & and the threaded hoses in the engine. compare the new pump with the old one make sure there identical. remove all traces of old gasket material from engine.

1997 Dakota v8 water pump replacement steps


Hope this helps!

Common Steps
  1. Disconnect the battery negative cable(s).
  2. Drain the cooling system.
  3. Remove the accessory drive belt.
  4. Remove the lower radiator hose (except Diesel).
  5. Disconnect the heater hose from the pump, if fitted.

WARNING Most cooling system hoses use "constant tension" hose clamps. When removing or installing, use a tool designed for servicing this type of clamp. The clamps are stamped with a letter or number on the tongue. If replacement is necessary, use only an OEM clamp with a matching ID.



f90cf3b.gif
Heater hose pipe O-ring (arrow): twist gently when removing or installing; check condition; lubricate with coolant before installing

CAUTION Always wear safety glasses when servicing contact tension clamps.


  1. Always use a new gasket when installing the water pump. Clean mating surfaces thoroughly before installation.
  2. This would be a good time to replace radiator hoses. At least, inspect them carefully for aging or other damage.
  3. If the heater hose pipe was removed, use thread sealant or equivalent on the pipe threads (if threaded), or lubricate any O-rings with coolant before installing.
  4. Check the accessory belt routing against the plate in the engine compartment before starting engine.
  5. Allow the engine to reach operating temperature and check for leaks.

3.9L, 4.7L, 5.2L, 5.9L, 8.0L Gasoline Engines
  1. Carry out the "Common Steps" above.
  2. Remove the upper radiator hose.
  3. Remove the fan and shroud assembly.
  4. On engines except 4.7L, remove the four water pump pulley bolts and remove the pulley.
  5. Remove the heater hose pipe mounting bolt, if fitted.
  6. On engines except 4.7L, loosen the bypass hose clamp at the water pump.
  7. Remove the seven water pump mounting bolts and, on the 4.7L, one nut.

WARNING Bolts may be of different lengths. Be sure to note their locations.


To install:
  1. Reverse the removal procedure.
  2. The 8.0L engine uses an O-ring to seal. Use a new one and lubricate it with petroleum jelly before installation of the pump. Also, use sealant on the threads of the heater hose pipe, position the pipe as shown before installing the pump and tighten the nut to 12 ft. lbs. (16 Nm).
  3. On pushrod engines, connect the bypass hose to the pump while installing it.
  4. Tighten the bolts to 30 ft. lbs. (40 Nm) on pushrod engines, 40 ft. lbs. (54 Nm) on the 4.7L engine.
  5. Spin pump to ensure the impeller is not rubbing against the timing chain case.
  6. When installing the heater hose pipe, ensure that the slot in the pipe bracket is bearing against the mounting bolt. This will hold the pipe in as far as possible to prevent leaks.
  7. Tighten pulley bolts to 20 ft. lbs. (27 Nm) on V-6 and V-8, 16 ft. lbs. (22 Nm) on the V-10.

Cooling system requires burp.


A large air pocket can sometimes be tricky to get rid of. The easiest way is to jack the front end up in the air with the wheels off the ground and support with jack stands, remove the radiator cap(make sure engine is cool) and allow to sit over night in this condition. The elevated front end will allow the air pocket to move to the most highest point and then escaping out the top of the radiator, after doing this procedure make sure to inspect coolant level in radiator and overflow reservoir and top off as needed.
