2002 Ford SVT Focus - Page 6 - Answered Questions & Fixed issues

Your computer is reading engine knock. Do not drive under hard conditions. You need to have it check out by a mechanic.

Clint, you might want to check your break switch to see if your button is stuck. It is right above your brake pedal. The pedal led actually hits the button of the switch. See if you can loosen it.

Have you checked the bulb?

there you go, if you need another diagram for one without AC its in that same page, remember to use belt dressing, go slowly, and if you need one, use a belt tensioner wrench to help you slide it off, a special trick is to put the belt on the water pump pulley last, as the rounded edge is easier to slide on to, as well as making sure the belt length is correct

Hi
You are going to have to check the battery supply leads from the battery to the alternator and to the starter solenoid / starter.
I would expect that one is loose of corroded.
Dont forget to check the earth points as well especially the one from starter to the chassis.

low speed fan relay is bad

serial number?

the problem may be the wiring too the fans there maybe a break in the circuit.

Only way too go about it is checking all cables that correspond with the radiator fan by using a circuit breaker tester.

it could be the filter for the PCV system. foam like?

This is a fairly expensive repair, I'd guess about $2000 or more. You have to pull the head, which generally means removing a lot of other things (time consuming). As long as the head is off, have the valves inspected and machined or replaced as needed, and check the head for warpage (flatness).

Can be due to the failure of the Thermostat valve in the inlet that can be open at all times thereby allowing the radiator to work even in cold condition. The thermostat failure can also cause the fan to work at all times thus not warming the engine.

use marvel mystery oil both in your fuel and in your oil it will clean your injectors and eat any sludge build up due to oil residue and make winter starts easier... hope you take this in this stuff workes wonders the ratio is on the back of the bottle on what you add to your fuel... but when you put in your oil remember not to over fill!!!!

the check engine light comes on for a problem to find out what problem you need to scan and read codes for example did you gas up and leave the car running this would code a p0440 evap system or the car runs rough you can have a p0300 misfire so you are asking if the transmission needs oil you would have to check the engine light is not design for that purpose so get it scanned or unplug the battery if you cant afford to test system and see if it comes back on

The key and car might need re-synchronising after changing the battery or pressing the buttons too many times when out of range.

Put the key in the ignition and turn the key to position 2 and back four times within 6 seconds.
After a beep the car is in programming mode for the next 10 seconds.
Press any button on the remote fob to synchronising.

Its the one in front of the convertor . The way it works is bank one is the sensor closest to the front of the vehile its in the pipe bank 1 senoer 2 would be the next closest to the front of the vehicle because you don't have a y pipe its a 4 cylinder engine

the engine diagram you should be able to find it pretty easy on internet but for you pulleys you should have a diagram under the hood some where around the hood hitch good luck hope that i gave you a good hint

its at the back of the engine ,not difficult but a lot easier with a ramp or a pit ,but it can be done jacking vehicle up and putting a stand under it .Bracket on back of starter to be removed as well .

if the button is flashing it usualy means there is a trouble code in the tranny see a tranny shop or your dealer

On this thing that.The most problem is that you will need to try a first step and the cheapest one is to have your cooling system flushed.If that don't help then more likely you have a bad heater core.

Follow the upper radiator hose from the radiator to the engine. The hose will be attached to the thermostat housing which is fastened to the engine with two bolts. While the engine is cold, remove these two bolts and lift up the housing to expose the thermostat. Replace the old thermostat with a new one. An auto parts store employee can help you purchase the correct thermostat for your particular application. When you install the new thermostat, be sure to use the rubber gasket that comes with it. Make sure you don't put the new thermostat in upside down. Sounds silly, but it does happen. Bolt the housing back down, careful not to over tighten the bolts since they most likely will be going into aluminum. Replace any antifreeze that may have been lost with a 50/50 solution of antifreeze and water. You can buy this already premixed by the gallon wherever you buy the thermostat.
