Re: I want to replace the thermostat
Follow the top radiator hose to the motor..there you will find a clamp.on the end of the hose. take it loose and move it out of your way. there are two bolts that hold the housing in place that you will need to pull and there you will find the thermostat

I just replaced the T-stat on my 2003 Focus ZX3 last weekend. I'm a novice; it was easy. You shouldn't have to remove anything except the T-stat housing. It's located on the right side of the block, across from the battery. You need a 10 mm wrench to remove the three bolts holding the housing onto the block. Removing the four hoses was the most difficult part. When they're off, the housing unit slides under and out. The T-stat and O-ring cost $20.
you have to drain the radiator there should be either a screw or a yellow plug on the bottom of the radiator. then from there you pull apart the thermostat housing you will need a new thermostat and gasket then gasket sealent. the you pull the hose from the housing then take a paint scraper and scratch all the crossion off then pull the housing off and then the thermostat and put everything back the same way
The alternator will be located in the front of the engine on the drivers side. To replace it you must loosen the idler pulley and remove the serpintine belt, once the belt is off you must unhook any wires goin to the alternater and then there are two bolts at the bottom of the alternater holding it in place. Remove those and the alternater is loose then it may take some jockying back and forth to get it out. Obviously at this point the new one can go in the same way the old one came out.
WORKING FROM THE FRONT; YOU NEED A SIZE 17 SOCKET ON A TBAR.THE
ALTERNATER IS ON DRIVER SIDE AT THE BACK.THERE ARE THREE BOLTS TO
LOOSEN (DONT TAKE THEM RIGHT OFF) . PULL THE ALTERNATER TOWARDS THE
FRONT OF THE CAR, SLIP BELT OVER CRANK PULLEY THEN OVER ALTERNATER
PULLEY .LEVER ALTERNATER BACK TO TIGHTEN BELT,THEN RETIGHTEN 3 BOLTS
From the top of the car remove the slide and anchor bolt from the alternater bracket. remove your 3 or 4 pin plug and diconnect the pos power line beside the 3 or 4 pin plug ( on the back of the alternater). now raise the car and from below remove the lower bolt that allows the alternater to swing back and forth. the bolt fits through the housing of the alternater. remove the belt. now the alternater is free. this lower bolt that was just removed attaches to a bracket bolted to the block. remove this bracket and the alternater will slide out of the bottom of the car. complete the above steps in reverse to install new part.
free the engine from the compressor and then remove the plug then first insert the drive belt on the smaller pulley side and after that try inserting the belt on the larger pulley side slowly by rotating the pulley slowly by stretching the belt with a rope
