Mitsubishi Galant 2005 4dr blower fan has no power

The radiator fan will not normally have power. It is only when the engine coolant thermostat detects high temperature it sets on the fan relay which starts the fan. So it is likely the thermostat or the fan relay are faulty.

I have a 4 cyl engine in my galant and the thermostat is found by following the LOWER radiator hose. You will need to remove the battery in order to gain access to the thermostat housing mounting bolts. There is a video on showing the removal and replacement of the thermostat and radiator for a 1999 mitsubishi galant.

Change the thermostat in the galant.

1. Raise the front of your Mitsubishi Galant with a jack and lower onto jack stands, or use wheel ramps. Disconnect the negative cable from the battery. Drain the coolant into a suitable container by opening the drain plug on the bottom of the radiator.
2. Step 2 Follow the upper radiator hose to where it meets the engine at the thermostat housing. Loosen the clamp at the engine end of the radiator hose and pull the hose off the thermostat housing.
3. Step 3 Remove the two bolts on the thermostat housing cover and pull off the cover. Note the position of the old thermostat and remove it from the thermostat housing. Place a rag in the thermostat housing and scrape any gasket residue from the inside of the thermostat housing cover.
4. Step 4 Take out the rag and insert the new thermostat in the same position as the old one, with the spring-side facing into the engine. Install the new gasket or o-ring, depending on the type of thermostat you are installing. Note that most late 1980s and early 1990s Galant models use a thermostat gasket.
5. Step 5 Replace the thermostat housing cover and tighten the bolts. Re-attach the radiator hose and tighten the clamp. Fill the radiator with new coolant, or use the coolant drained from your Galant earlier if it's relatively new and clean.
6. Step 6 Start your Mitsubishi Galant and run with the heater on high until it reaches operating temperature. Make sure the heater is blowing warm air to ensure the thermostat is working properly. Check for leaks and tighten the radiator hose clamps if you detect any.

My teperature gauge on my mitsubishi galant show's it is overheating 5 minutes after i start my motor

Is the car actually overheating? Are you adding coolant often or occasionally? Check your thermostat to see if it's working properly. If it's stuck closed, that's about how long it would take start to overheat. To check, remove thermostat, boil water in an old pot, drop thermostat in, it should open. If it doesn't, replace it.
