Question about 1995 Isuzu Trooper

1 Answer

Coolant leak I have the same problem; one of the rubber coolant hoses that disappersbehind the engine broke off wherever it is connected. From the pieceleft in the hose, there was a plastic connector inside the hose goingto whatever is behind the engine, and it finally degraded and broke off(1995 model). Please tell me I don't have to remove the engine to fix; i don't see any other way as there is no room to work.

I have a antifreeze leak on the back side of my 3.5 liter kia sorento motor,I took all the heater hoses loose and they look fine. What else could be leaking coolant the Y that connects the hoses is ok


Hi Kevin.

The general route of coolant will be the engine block, the heater core in/near the dashboard, the radiator, and, often, a coolant overflow reservoir that buffers you from leaks if your coolant gets extra hot or bubbly.

So, along with the heater hoses, there are the radiator hoses, either end. Hose connections to the block. Hose to wherever your coolant check/refill container is. The drain plug at the bottom of the radiator.

There is one other place that coolant can go, though you gotta hope this isn't it. If your head gasket is on it's last legs, coolant can start leaking into your cylinder head. This can show up overtly as white smoke, not so smooth running, or mysterious random moments where a hose suddenly bursts or pops loose. Or it can just be an occasional pinhole leak that's hard to detect.

One of the biggest tells - park the car on a flat smooth surface overnight after you've driven it a while. When you come out the next day, is there coolant on the ground anywhere. if yes, the location can help you track it. if no, then exit through the cylinder head may be the culprit. You'd want to run a compression check to make sure, and then contemplate whether fixing it is worth it on a twelve year old car.

Good Luck!

How to check you Volkswagen & Audi oil cooler for leaks.


If you own a Volkswagen or Audi and have coolant in your engine oil or oil in your coolant you may have a failing oil cooler. This may have been misdiagnosed as a bad head gasket.

Before spending hundreds or thousands repairing a head gasket that may not be the problem you can perform this relatively easy check of your oil cooler which is a common problem on many Volks/Audi models that use oil filter type of oil cooler. This type of cooler is located between the oil filter and the engine block. The oil filter screws onto the oil cooler. It has two rubber coolant hoses attached to it and is made from aluminum.

The oil cooler works by passing engine oil through the body of the cooler. The engine oil passes over what resembles a radiator inside the cooler. This 'mini radiator' is passing engine coolant in through one of the hoses and out through the other. When working properly the oil and coolant is kept separated. Over time the passages inside the cooler can corrode and the oil and engine coolant inside can mix. This can lead to coolant in your engine oil (which may produce a milky substance on the inside of the oil filler cap) or oil in the coolant (which you may be able to see in the coolant reservoir as a dark ring or oily film).

To test your cooler for leaks you will need a few basic tools and about 3 hour of your time. (To allow for the engine to cool)

-Basic ratchet set and set of screwdrivers.

-One straight 5/8 inch plastic heater hose connector. You can find thisat most auto parts or plumbing supply stores. Cost about $1.

-A pan to catch some coolant that will spill.

This procedure is best done on a lift but can be done using jack stands as well. This MUST be done with a cool engine to avoid burns from coolant.

-Lift or jack the front end of the car. (If you don't know how to safely jack a car onto jack stands, DO NOT proceed any further. Take the car to your repair shop and have them follow these instructions)

-Remove the plastic cover under the front of the car (if your model has this) to expose the oil filter. The oil filter is a cylindrical part that sticks out from the side of the engine.

-The oil filter is screwed into the oil cooler. You will see two rubber hoses connected to the oil cooler.

-Using a flat screwdriver or socket loosen the clamps connecting the hoses to the cooler. Now have the plastic connector handy. Remove the hoses from the cooler, you may need to pry on them with a screw driver.I find that twisting them to break their seal works well. Catch any coolant that spills in the pan.

-Take each rubber hose and push them onto the plastic connector being sure to keep the clamps on the hoses. Tighten the clamps. (Not too tight, just snug) Now you have just eliminated the cooler from the system temporarily.The rubber hoses are now connected to each other.

-Wipe the oil cooler clean with a rag so it is easier to see any leaks that might develop.

-Now start the engine and let it run to normal operating temperature.This means at least 15 minutes but to be sure you find any leaks I suggest half an hour.

-Keep a close eye on the 2 metal tubes on the oil cooler. (The ones you removed the rubber hoses from) You are looking for engine oil to begin seeping out. It will appear golden brown to black in color.

If you see oil coming from those tubes you have found your problem. You will need to buy and install a new oil cooler.

If you don't see any oil leaking you will need to look elsewhere for the trouble. Possibly a head gasket, unfortunately.

-Let the engine cool for a few hours before reattaching the oil cooler. It is the reverse of removal.

-Replace any lost coolant with the same amount you caught in the pan.

And there you have it. A pretty simple procedure that may save you a bunch of cash in repairs.

I am losing coolant on my car and I see that the coolant from the reservoir is leaking from a little black rubber hose that"s connected to the firewall.


The black rubber hose may be bad and needs replaced. This hose should connect to the radiator at the radiator cap and run along the firewall to the coolant reservoir. Also the coolant reservoir might be cracked and leaking on to the rubber hose, if this is the cause just replace the coolant reservoir which may be a dealer only item, check at you local auto parts store and they will tell you if it is a dealer only item. If you have to replace the coolant reservoir, make sure the car has not been run and the coolant at the radiator is cool, cause when the engine is hot the hot coolant runs into the coolant reservoir till it cools and returns to the radiator when engine is turned off and cools.

ENGINE COOLANT LEAK FROM BACK OF ENGINE WHERE IS THE WATER PUMP LOCATED


Hopefully just a water hose or connection leak...some parts of these hoses are now metal, and rust away...these factory metal hoses are dealer, and salvage yard only...Many times you can replace the entire metal line with a rubber line...as long as you can connect to both sides...there is a water hose that runs under the coolant overflow, to the firewall...(many times the culprit)...the water pump on your motor is under a pulley located on the front of your engine...Hope this helps.

Heater-coolant hoses


If the car has dual-zone heating, then that hose should be teed into the other return hose.
