I have a 95 isuzu rodeo v6 3.2L 4x4 ..i just replaced the oil cooling hoses(upper and lower)..now when the engine warms and the thermostat opens coolant appears to be leaking from between the motor and the transmission.. i dont know what this could be.. any one have any suggestions/// pllease send them to [email protected]..... thanx
I have a 98 Trooper leaking engine coolant from above the the oil pan and can't see where the source is. It leaks alot after it has been parked for several hours, and very little when the engine is running.
All hoses have been replaced and no change.
The dealer replaced the water pump at 130K miles, now have 170K.
Same problem.

asked many time here, and same answer.
if you look , you see it, then see its not possible to get to the 2 rear bolts (telling you what?)
pull engine block, ? no
pull intake, yes.
You need to pinpoint the problem by measuring he temperatures of the system.
1. If the engine is 190f and the upper hose is warm, but the lower hose is cold, you either have a thermostat problem, or a bad water pump.
2. if both the hoses are as hot as the engine then you have either a bad fan (is it running at normal speeds?) or a bad radiator.
3. When cold, leave the cap off, is it full? do you see continuous bubble as it runs? when you start it does coolant spray out (from a cold start) if so then you could have a bad head gasket.
Properly drain the cooling system into a suitable container.
Disconnect the fan motor and motor connector.
Disconnect the upper and lower radiator hoses.
Disconnect and plug the automatic transaxle cooling lines at the radiator, if equipped.
Disconnect the coolant reservoir overflow hose.
Remove the radiator attaching bolts and brackets.
Remove the radiator with the cooling fan attached.
Remove the cooling fan and shroud from the radiator.
NOTE: Check all cooling system hoses for any signs of damage, leaks or deterioration and replace if necessary. To install:
Attach the cooling fan and shroud to the radiator and install the assembly.
Attach the radiator bolts and brackets. Tighten the radiator bracket bolts to 7 ft. lbs. (10 Nm).
Connect the coolant reservoir overflow hose.
Connect the automatic transaxle cooling lines to the radiator, if equipped.
Connect the upper and lower radiator hoses.
Connect the fan motor and thermo-switch wire connector.
Refill the system with the proper type and quantity of coolant, check for leaks and bleed the cooling system.
Reconnect the negative battery cable.

with my experiance on these engines it's usually the upper outlet hoses running from the heads into a t then into the upper radiator hose they are pain to replace but 3 out of 3 of my v6 isuzu's have had the same problem you'll have to pull off the theromstat and the coil pack the hoses are very small and run from the end of the heads one on each into a t then into the radiator hose just under the housing
Recheck the connection of the upper hose that leads to the engine side with particular attention to the lip of the metal tube. In most instances, it would be the hos not pushed in properly or a clamp that is not tightened wholly encompassing the hose. Additionally, you may want to check the thermostat housing for any cracks/leaks.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
