Coolant leak is most likely the water pump. It is driven by the timing belt. There is also a plate on the RH head that has O rings on it that can leak[rare]. Rad fan running all the time could be a couple of things. Defective relay,defective PCM,defective temp sensor,short in the wiring.
thanks for responding. question, I just bought the dealers service manual, and it says when replacing the timing belt to also take valve covers off and loosen rocker arm assy. I have done timing belts before, but I have never had to do that. It is the 3.5l, and I am wondering if it is really nec.
any help is deeply appreciated.
hey G here you go i'll send send pictures,moe
The water pump on all models can be replaced without discharging the air conditioning system. WARNING:DO NOT REMOVE PRESSURE CAP WITH THE SYSTEM HOT AND UNDER PRESSURE BECAUSE SERIOUS BURNS FROM COOLANT CAN OCCUR. NOTE:It is normal for the water pump to weep a small amount of coolant from the weep hole (black stain on water pump body). Do not replace the water pump if this condition exists. Replace the water pump if a heavy deposit or a steady flow of engine coolant is evident on water pump body from the weep hole (shaft seal failure). Be sure to perform a thorough analysis before replacing water pump.
[ol][*]Drain cooling system (Refer to 7 - COOLING - STANDARD PROCEDURE). NOTE:The water pump is driven by the timing belt. [*]Remove engine timing belt (Refer to 9 - ENGINE/VALVE TIMING/TIMING BELT/CHAIN AND SPROCKETS - REMOVAL).[*]Remove water pump mounting bolts (Water Pump - 3.5L Engine). Note position of longer bolt for proper re-installation.[*]Remove water pump body from engine (Water Pump - 3.5L Engine). [/ol]
