Q: Engine heating issue.

asked by on

While driving the ac cut off and after a while I noticed the engine light come up and disappeared. I noticed that the heat gauge has spiked so I stopped the car and opened the hood and found that the outlet valve from engine to radiator gave off the thermostat has popped out of its place, the coolant level was zero, then towed to the mechanic. The engine is running no difference found in the engine noise, it runssmooth. The mechanic found that the water pump is faulty and replaced it thermostat is also replaced along with it's housing and new coolant is added. Mechanic took the car for a drive and found that the engine heat indicator gauge increases above the middle point, please advice on what the issue would be.

My car is Chevy Optra Petrol 1.6ltrs My car has 29000 miles.
My car has a manual transmission.

Hi there. From the description you provided, it would appear the engine does not have a head gasket problem from being overheated. If the temperature climbs above the middle point while the vehicle is at a stop it could be a cooling fan problem. If the temperature climbs above the middle point travelling down the road it could be a restriction inside the radiator. There is also the possibility that the replacement thermostat is bad. The car running hotter than normal should be repaired, so additional damage does not occur. I recommend having your vehicle inspected by a certified technician, such as one from YourMechanic.
