Hi there.
Yes, You do not have to take the engine out for this operation.

First, make sure that it is the coolant thermostat that is faulty.

When starting the vehicle from cold with a faulty thermostat, the radiator will start to warm almost instantly. The temperature gauge will stay low for a long time, and getting cabin heat within 2 minutes will be impossible.

Thermostats are nearly always located on the engine at the hose outlet to the top of the radiator. As it is at the top front of the engine, access is usually straightforward once any soundcovers etc are removed.

Other related problems are - Electric fan problems (caused by faulty temperature switch) and temperature sensor reradings - caused by faulty sensor, or electrical supply.

Thanks for using Fixya! If this provides a solution, please rate as such. Thanks.

Just purchased an AO Smith condenser fan motor, installed it but it runs counter clockwise, how do i reverse it to run clockwise?

Hi, this is very easy to do. On the back end of the motor you will see a pair of wires plugged in to each other. Kill the power and just unplug and reverse these wires. This will reverse the rotation of the condenser fan motor. If you have no wires, check for an arrow on the motor housing. It will only go one way if there is one, and you will need to take it back. 2 pair of wires...., just reverse them very easy. Tie or tape them away from the blade.

Changed battery and now the heater stays on regardless of the AC setting

I don't know the answer right off, but I can tell you how to trouble shoot to see if there is something wrong with the thermostat or if something happened to the furnace. The thermostats only purpose is to act like a switch, just like a light switch, and should never be stuck to one setting unless something internal has gone wrong. Now, to troubleshoot, you can take the thermostat off the wall and you will see the colored wires attached to terminals marked according to wire colors. If you take a jumper wire, or even some needle nose, you can jumper the R terminal to the G terminal and see if only your fan motor comes on in the furnace, then you will want to jumper the R and the Y together and make sure that only your A/C and fan motor come on without the heat. Be sure not to touch any of the terminals to the other ones besides the ones described, otherwise you may blow a fuse or damage something else. Don't worry about the electric current, it is only 24volts and you will barely be able to feel it, not saying it's okay to grab ahold of lol! If any of these don't work as they should by jumping the thermostat wires inside the house, then the problem is the thermostat which should be replaced. Just in case, depending on the system you have, you might have 4 wires, 5 wires, or 7 wires. I will explain what the common terminals mean. R(red) is Power, W(white) is Heat, Y(yellow) is A/C, G(green) is Fan Motor, and B or C (usually blue) is Common. You may have more than that, but those are the basics and all your doing is acting as the switch and applying power from the R terminal to whatever you want to run. I really hope this helps and good luck!

Outside unit fan not working

The fan is told to come on by the control board that is being sent a signal by the thermostat. There are several things that will contribute to the fan not coming on:
1. The fan capacitor may be bad. When the signal is sent for the fan to come on, try to get it started with a spray from the water hose. If the fan gets up to speed, you have a bad capacitor.
2. The fan motor may be bad. You can remove and test the motor or replace.
3. The control board in the outside unit may be bad. Usually, this is difficult to troubleshoot without a meter and schematic. What you CAN do is to take all of the power off of the unit, including the power from the thermostat, and open the enclosure for the control board. Check for loose and corroded connections. You can clean terminals effectively with the eraser end of a pencil.
4. Check the power relay where thewiring comes into the unit. Make sure that the contacts are not burned, or welded together.
Best regards, --W/D--

If you take thermostrat back off and connect the wires together will baseboard heater get hot. If not you may have bad heater. If it gets hot your new tstat may be bad. The way you have it wired is correct. Most line voltage tstats have a ground screw. Your 's may not but will work without one .

Check your furnace for power. will be 4 wires. power ground and 2 thermostat wires. Check for power at the time delay relay, if you have power there check for power going in the fan motor, if power in motor wire, motor is bad. If no power in motor wire and power going to circuit board take the 2 thermostat wire apart and wrap the 2 together comimg from the thermostat. Fan will stat in about 30 seconds. If it does you need a control kit in the ac. But sounds to me like you have a furnace problem.
