Difficulty: Beginner · About 2 min · Hyundai Elantra
Replace the coolant reservoir on a 2007–2010 Hyundai Elantra with the engine completely cool, reusing the cap only if sound and refilling with the specified coolant.
Tools you will need
- 10mm Socket
- Ratchet
Parts and supplies
- Coolant reservoir
- Vehicle-specified coolant
Steps
Let the engine cool
Park on level ground and wait until the engine is fully cold. Never open a hot cooling system; coolant can cause severe burns under pressure.
Remove the old reservoir
Unbolt the reservoir and place a drain pan below the hose. Disconnect the hose and lift the tank out, capturing any coolant that spills.
Install the replacement tank
Transfer the cap if it is undamaged, connect the hose securely, and seat the new reservoir on its mounts. Reinstall its bolts without overtightening the plastic tank.
Refill and inspect
Add the vehicle-specified coolant to the proper cold fill mark. Check the hose connection for seepage and recheck the level after the system reaches operating temperature and cools again.
Check your vehicle’s repair manual for exact specifications and fit.
