How to Look for Wear or Leaks on Hoses and Clamps in a Mitsubishi 3000GT
- 1). Find the upper and lower radiator hoses, which go from the radiator to the engine and from the radiator to your exhaust manifold. The coolant hose runs from your radiator to your intake manifold. The heater hoses run from the radiator to the back of the engine block, as do the hoses attached to the intake manifold.
- 2). Inspect each hose for cracks, frisions or tiny tears. If you find any, replace the damaged hose immediately. Wipe away grease before checking your hoses and clamps so you can easily inspect the parts.
- 3). Run your hands down the hoses to make sure they feel firm, not soft or pliable. If the hoses are soft to the touch, replace them.
- 4). Squeeze each hose at both ends and pay attention to how it feels. If you can feel ridges when you pinch the ends of the hose, that's an indication that the hose is failing from the inside and needs to be replaced.
- 5). Check the ends of each hose to ensure it's fully connected and not slowly slipping free.
- 6). Use a screwdriver to snug up the clamps at the end of each hose. Depending on the year of your Mitsubishi 3000GT, you'll need a Phillips or flathead screwdriver to do this. Make sure the clamp is snug but not too tight. If you tighten the clamps too much, you can create a tear in the surface of the hose.
- 7). Start the car and move it to a clean, dry location. Let the Mitsubishi 3000GT run for about 5 minutes, then inspect the surface below. If you see liquid, you have a leak. Inspect the hoses and clamps again, if necessary, to see if you can determine where the leak is coming from.
