Thermostat or gasket?

Asked by Jan 17, 2018 at 12:54 AM about the 2014 Honda CR-V

Question type: Maintenance & Repair

I need to top my coolant bottle up once a
week. My car never overheats but i havent
heard the fan kicking in. Any ideas?

Your overfilling it ... every time the radiator puts the coolant from expansion it overflows the coolant tank ,,, then when the engine cools it sucks the coolant back into the engine minus what you added that overflowed so the tank looks like it did the last time you filled it


some small motors can take a long tome before the fans come on , some will click on when the ac, gets turned on ,, I would watch the temp. gauge it should reach operating temp. and stay there


Only fill the coolant bottle to the indicated "HOT" or "COLD" level. This level is usually imprinted on the bottle. If you are doing it properly and not overfilling it there may be a coolant leak or the coolant could be going out the exhaust via a bad head gasket or cracked cylinder head. A cooling system pressure test should reveal any leaks you may have. How many miles on this Honda?
