INTERCOOLER Coolant System Check (CELICA Turbo)
- Intercooler coolant reservoir should be filled up to bottom of filler neck. There should be no rust or scale deposits. There should be no oil deposits.
- If necessary, drain and replace coolant. Drain plug is located on bottom of intercooler radiator. Use a 50-50 mix of water and ethylene-glycol coolant. To bleed system, turn ignition on with engine off. Open throttle valve which causes coolant pump to operate. Refill with coolant, if necessary.NOTE: If the coolant level drops too low, coolant level switch will turn coolant pump off.
- Start engine and accelerate a few times to 3000 RPM. Stop engine and recheck coolant level. If necessary, check intercooler system for leaks with radiator pressure tester. Refer to the INTERCOOLER COOLANT PRESSURE SPECIFICATIONS table.
