Q: How to remove the coolant reservoir in Hyundai Elantra?A: In 2010 and earlier 1.8L and 2012 and earlier 2.0L models, remove the coolant reservoir cap, and overflow hose, and detach the reservoir by loosening three bolts. For 1.4L and 1.6L models, the coolant hoses need to be disconnected, which can then be removed from the inner fender panel.
