Automatic Transaxle Cooling System Hyundai Santa Fe III

Description

The ATF warmer is mounted on the valve body cover to reduce oil viscosity friction by increasing oil temperature under cold condition, which in turn improves fuel efficiency. It is serial mounted on the entry of the Electronic Throttle Controller (ETC), as shown in the illustrated diagram, and minimizes the effects of cabin heating system.

Scheme 37

1. Engine coolant is used for circulating heat in order to heat and cool the transaxle oil.
2. Rapidly elevates the transaxle oil temperature during the initial cold start of the engine.
3. Prevents over heating of the transaxle oil while the vehicle is moving.
4. Transaxle oil warm-up and cooling can be done with a single system.
5. The water coolant and oil are separate in order to exchange heat.

1. Drain the coolant. (Refer to " «COOLANT»(/hyundai/santa-fe/iii-2012-2016/remont/cooling-system-mechanical/#engine-cooling-system) ")
2. Remove the air cleaner assembly and air duct. (Refer to " «AIR CLEANER»(/hyundai/santa-fe/iii-2012-2016/remont/exhaust/#intake-and-exhaust-system) ")
3. Remove the battery and battery tray. (Refer to " «BATTERY»(/hyundai/santa-fe/iii-2012-2016/remont/charging-system/#charging-system) ")
4. Remove the under cover (A). Tightening torque: 7.8 ~ 11.8 N.m (0.8 ~ 1.2 kgf.m, 5.8 ~ 8.7 lb-ft)
5. Disconnect the coolant hose (B) after removing the coolant hose clamp (A).
6. Disconnect the hose (B) after removing the automatic transaxle fluid cooler hose clamp (A). CAUTION: When hose & pipe assembly Align marking of pipe (B), marking of hose (A), and matching color each other.
7. Remove the ATF Warmer (A). Tightening torque: (A) 7.8 ~ 11.8 N.m (0.8 ~ 1.2 kgf.m, 5.8 ~ 8.7 lb-ft)

Installation

1. Install in the reverse order of removal. NOTE: Adding automatic transaxle fluid. (Refer to " «FLUID»(/hyundai/santa-fe/iii-2012-2016/remont/automatic-trans/#automatic-transaxle-system-general-information__fluid) ") Adding coolant. (Refer to " «COOLANT»(/hyundai/santa-fe/iii-2012-2016/remont/cooling-system-mechanical/#engine-cooling-system) ")
