Radiator fan not working? Unplug fan switch on the thermostat housing and jumper the pins in the plug on the harness side. Fan should now start immediately when you turn the key on. If it doesn't start, troubleshoot the motor, fuse, and relay. If it does run all the time, test drive with the jumper in and confirm no overheating. If it doesn't overheat, the switch must be bad.

 

Thank you. i'll try this out

 

Hey Mike,

Have you tried "burping" your coolant system? Air pockets in your coolant system can cause overheating because there will not be enough coolant in the cooling system, even if the radiator and coolant reservoir look full. So although you have observed a sufficient coolant level in your Civic, it is possible that there are air bubbles trapped in the coolant system.

Here's the simple procedure for performing this vital maintenance job:

1) Add a mixture of one-half water and one-half antifreeze to the radiator. Fill it right up to the top.

2) Fill the overflow/coolant reservoir with the same 50/50 mixture (the reservoir tank is displayed in this '97 Civic Cooling System diagram.

3) Leave the radiator cap off, turn the engine on and let it run until the radiator "burps": You will see the coolant level drop and may see or hear a large air bubble come to the top as the system burps.

4) Keep an eye on the temperature gauge throughout this process.

5) Refill the radiator to the top and coolant reservoir as needed.

6) Put the radiator cap back on.

7) Note that if the engine runs hot after this procedure there may have been another pocket of air that "burped." Let the engine cool down and then add more coolant to both the radiator and the coolant reservoir.


Hope this resolves your overheating issue, man!
