Question about 1995 Isuzu Trooper

1 Answer

Undertermined coolant leak location

My '95 Trooper,w/200K mi., developed a serious coolant leak from somewhere other than the front of the motor.All the liquid seems to be leaking from the rear? of the motor and running down onto the frame cross member.
A local garage suggests there is some kind of cross over tube between the cylinder banks at the rear and that the gaskets must be bad.
I have no access to a manual so cannot verify this.
Do these motors have "freeze out" plugs ??
I know years ago, it wasn't unheard of for these to sometimes rust through,causing a coolant leak.
There are no factory authorized repair shops in my area anymore.
Do you have any suggestions as to what may be causing this sudden leaking???
Thanks for your help
Craig

    I have the same problem. I am changing the water pump to see if that corrects it. It is time to change the pump in anyway.

    I have the same problem; one of the rubber coolant hoses that disappers behind the engine broke off wherever it is connected. From the piece left in the hose, there was a plastic connector inside the hose going to whatever is behind the engine, and it finally degraded and broke off (1995 model). I'm going to have to get a manual to see where exactly it connects and figure out how I'm going to get it reconnected without have to take the engine out.

    the two pipe connectors that come out from the heater core are plastic; after awhile they degrade and become brittle and break off. The heater core will have to be removed and repaired/replaced. Get ready to remove the dash of the car.

Core plugs they are called ,not freeze plugs and they are for the manufacture of the block to remove the casting sand.if you keep antifreeze in system they do not corrode not sure what engine in these things only ever seen one that i imported for someone and the paperwork for this was horrendous.look behind engine with a torch and a mirror and i have no doubt you are correct about the core plugs .only ever seen a diesel version .

Motor is ticking vey bad and it keeps using a lot of antifreeze


You may be having what was a common problem in Malibu engines. The intake manifolds can develop coolant leaks (usually externally), normally between 70k-100k miles. Sometimes the leak goes internal and into the engine oil. Run the engine and check the dipstick. If the oil seems overly full and/or is a foamy chocolate-milk-like consistency, then you have issues that must be repaired immediately to avoid serious engine damage.

95 isuzu trooper i have waterf coming out the back of the motor cant find any cracks what else could it be


Check closely at front thermostat area. numerous hose connections there and it is probably leaking there and running down the lifter valley out the back. Check heater hose connections at firewall also.
Good luck

My mazda mpv 2001 coolant leaking somewhere. Filled it Saturday full line and is at low level monday afternoon.Where is it going? Van does not overheat


1. External Leaks
You need to get the vehicle to a mechanic to check all flexible coolant hoses, hose connections, around the exterior of the water pump and the entire radiator. To do properly the vehicle also needs to be on a hoist. If there is an external leak you should find coolant dripping from the front of the car while the engine is idling and the cooling system is fully pressurized. However it depends how bad the leak is and it's location.

2. Internal Leak

If coolant is leaking into the engine this is a serious problem and needs to be identified by a competent mechanic. For example, if you have a blown head gasket coolant will blow into the engine and contaminate the engine oil. If you check the oil in the engine's sump it should be completely free from coolant contamination.
You should also check the coolant in the radiator for any signs of oil contamination. If there is coolant in the oil then there will also likely be engine oil which has blown into the engines coolant passages and then mixed with the coolant.
IF you can find traces of coolant in your engine oil (or oil in the coolant) the likely problem will be a blown head gasket and the head on the engine will need to be removed and inspected .

Blown head gaskets are usually a result of an owner allowing the engine to overheat as a result of low coolant level, failed water pump or faulty thermostat. Overheating can also cause major damage to the head on the engine.

Theres coolant leaking from somewhere i cant see i know its not from the radiator or or hose unless there's another hose i cant see. the leak is located under the motor mount running down the tranny on...


really this could be one of several issues, does the vehicle run Hot, are you having to fill the reservoir with water or coolant, there is a hose that runs from the cap (overflow hose) to the reservoir, in addition to the upper and lower hoses, finally the water pump. the water pump is equipped with weep holes, which allow fluid to weep out when the pump is bad. finally the thermostat, hopefully one of these can solve your issue, good luck!

Low coolant


the fluid has to be going somewhere. run the car so that the coolant gets flowing look very carefully all over under the hood. i dont know but if you ever get an antifreeze smell while in the car it may be your heater core.

1995 isuzu trooper manual transmission is leaking fluid from the gear box bolt. i was wondering if this is motor oil or is there transmission fluid somewhere i need to fill or check?


Hello smeet3992: The transmission uses 5w-30 for tempretures up to 95 degreese in tempreture. Uses 15w-40 for all tempretures greater then 50 degreese. If you are in an area that has extreme fluctuation in tempretures I would use the 15w-4o engine oil. I also senrt a picture of where to check the oil at. Make sure you pull the right plug. The reverse idler pin has the same size bolt head.
