How do replace the thermostat on a 1997 Hyundai Elantra?

Answer 1

CAUTION: Some models are equipped with anti-theft-radio make sure you have the activation code before disconnecting battery * Disconnect the negative battery cable * Drain the cooling system save coolant if its relatively new * Follow the upper radiator hose to the engine to locate the thermostat housing * Loosen the hose clamp then detach the hose from the fitting.If stuck grasp it near the end with a pair of large adjustable pliers and twist it to break the seal and pull it off * Remove the thermostat housing cover bolts and then remove the cover.If the cover is stuck tap it with a soft-face hammer to jar it loose.Thermostat will be right there just pull it out
