GENERAL INFORMATION

The cooling system is designed to keep every part of the engine at appropriate temperature in whatever condition the engine may be operated. The cooling method is of the water-cooled, pressure forced circulation type in which the water pump pressurizes coolant and circulates it throughout the engine. If the coolant temperature exceeds the prescribed temperature, the thermostat opens to circulate the coolant through the radiator as well so that the heat absorbed by the coolant may be radiated into the air. The water pump is of the centrifugal impeller type and is driven by the drive belt from the crankshaft. The radiator is the corrugated fin, cross flow type.

INTRODUCTION

The system cools the engine so that it does not overheat and maintains the engine at an optimum temperature. The system components are the radiator, water pump, thermostat, radiator fan, condenser fan. Possible faults include low coolant, contamination, belt loosening and component damage.

TROUBLESHOOTING STRATEGY

Use these steps to plan your diagnostic strategy. If you follow them carefully, you will be sure to find most of the engine cooling faults.

  1. Gather information from the customer.
  2. Verify that the condition described by the customer exists.
  3. Find and repair the malfunction by following the SYMPTOM CHART.
  4. Verify that the malfunction is eliminated.

Scheme 3: DIAGNOSIS
Scheme 3: DIAGNOSIS
  1. STEP 1. Check for coolant leaks. WARNING: When pressure testing the cooling system, slowly release cooling system pressure to avoid getting burned by hot coolant. CAUTION: Be sure to completely clean away any moisture from the places checked. When the tester is removed, be careful not to spill any coolant. When installing and removing the tester and when testing, be careful not to deform the filler neck of the radiator. Check that the coolant level is up to the filler neck. Install a radiator tester and apply 160 kPa (23 psi) pressure, and then check for leakage from the radiator hose or connections. Q: Is leakage present from the radiator hose or connections? YES: Repair or replace the appropriate part, then go to Step 2. NO: There is no action to be taken.
  2. STEP 2. Retest the system. Q: It there still coolant leakage? YES: Return to Step 1 . NO: The procedure is complete.

Scheme 4: DIAGNOSIS
  1. STEP 1. Remove the radiator cap and check for coolant contamination. Q: Is the coolant contaminated with rust and oil? YES: Replace it (Refer to «ENGINE COOLANT CHANGE < 2.0L ENGINE NON-TURBO, 2.4L ENGINE >»(/mitsubishi/lancer-evolution/x-2007-2016/remont/cooling-system-mechanical/#engine-cooling-except-lancer-evolution__engine-coolant-change-20l-engine) ) or (Refer to «ENGINE COOLANT CHANGE < 2.0L ENGINE TURBO >»(/mitsubishi/lancer-evolution/x-2007-2016/remont/cooling-system-mechanical/#engine-cooling-except-lancer-evolution__engine-coolant-change-20l-engine) ). NO: There is no action to be taken. Go to Step 2.
  2. STEP 2. Check the radiator cap valve opening pressure. NOTE: Be sure that the cap is clean before testing. Rust or other foreign material on the cap seal will cause an improper reading. Use a cap adapter to attach the cap to the tester. Increase the pressure until the gauge indicator stops moving. Minimum limit: 83 kPa (12 psi) Standard value: 93 - 123 kPa (14 - 18 psi) Q: Does the reading remain at or above the minimum limit? YES: Go to Step 3. NO: Replace the radiator cap. Then go to Step 5 .
  3. STEP 3. Check thermostat operation. Refer to «THERMOSTAT CHECK»(/mitsubishi/lancer-evolution/x-2007-2016/remont/cooling-system-mechanical/#engine-cooling-except-lancer-evolution) . Q: Does the thermostat operate correctly? YES: Go to Step 4. NO: Replace the thermostat, then go to Step 5 .
  4. STEP 4. Check the drive belt for slippage or damage. Refer to «DRIVE BELT TENSION CHECK»(/mitsubishi/lancer-evolution/x-2007-2016/remont/mechanical/#engine-mechanical-20l-non-turbo-except-lancer-evolution) . < 2.0L ENGINE Non-turbo > Refer to «DRIVE BELT TENSION CHECK»(/mitsubishi/lancer-evolution/x-2007-2016/remont/mechanical/#engine-mechanical-20l-turbo-except-lancer-evolution) . < 2.0L ENGINE Turbo > Refer to «DRIVE BELT TENSION CHECK»(/mitsubishi/lancer-evolution/x-2007-2016/remont/mechanical/#engine-mechanical-24l-except-lancer-evolution) . < 2.4L ENGINE > Q: Is the drive belt loose or damaged? YES: Adjust or replace the drive belt, then go to Step 5. NO: There is no action to be taken.
  5. STEP 5. Retest the system. Check the engine coolant temperature. Q: Is the engine coolant temperature abnormally high? YES: Return to Step 2 . NO: The procedure is complete.

ENGINE COOLANT LEAK CHECK

WARNINGWhen pressure testing the cooling system, slowly release cooling system pressure to avoid getting burned by hot coolant.
CAUTIONBe sure to completely clean away any moisture from the places checked. When the tester is taken out, be careful not to spill any coolant. Be careful when installing and removing the tester and when testing not to deform the filler neck of the radiator.
  1. Check that the coolant level is up to the filler neck. Install a radiator tester and apply 160 kPa (23 psi) pressure, and then check for leakage from the radiator hose or connections.
  2. If there is leakage, repair or replace the appropriate part.

RADIATOR CAP OPENING PRESSURE CHECK

Note. Be sure that the radiator cap is clean before testing. Rust or other foreign material on the radiator cap seal will cause an improper reading.

  1. Immerse the thermostat in water, and heat the water while stirring. Check the thermostat valve opening temperature. Standard value: 87 ± 1.5°C (189 ± 3°F) < 2.0L ENGINE Non-turbo, 2.4L ENGINE > 76.5 ± 1.5°C (170 ± 3°F) < 2.0L ENGINE Turbo >
  2. Check that the amount of valve lift is at the standard value when the water is at the full-opening temperature. NOTE: Measure the valve height when the thermostat is fully closed, and use this measurement to compare the valve height when the thermostat is fully open. Standard value: Full-opening temperature: 95°C (203°F) < 2.0L ENGINE Non-turbo, 2.4L ENGINE > 90°C (194°F) < 2.0L ENGINE Turbo > Amount of valve lift: 8.5 mm (0.33 inch) or more
