Question about 2000 Ford Focus

1 Answer

I have a 93 ford ranger. I replaced the water pump, thermostat, and temperature sensor. Now the problem is my check engine light turns on and off regularly, and my temperature gauge goes moves to the right like it wants to overheat but then goes back down and it does this over and over. Not sure what to do next?

Hi there,
The temp guage would not have anything to do with the engine light i wouldnt think, take it to a mechanic who has the right diagnostic equipment to extract the codes to tell you what that problem is. As far as the temp guage goes it might be that its riding on the new thermostat as long as its not overheating it should be fine.
I hope this helps.

Looks like you need to replace the coolant temperature sensor for the computer. This will make the engine run rich all the time. You can simply check it with a scan tool with live data capability. With the engine warm read the engine coolant temperature. My guess is it will read very cold even with the engine warm. If so replace it and the truck will be running like new

I have a 2002 ford ranger that runs normal while engine is running but gets hot when i shut off engine


SOUND LIKE ENGINE OVERHEATING.USE A INFRA THERMOMETER ENGINE TEMPERATURE SHOULD NOT EXCEED 104 CELSIUS WHICH IS 220 DEGREES IF ENGINE EMPERATURE GOING OVER 230. THERMOSTAT STICKING PARTIALLY CLOSED,WATER PUMP FAILING CHECK WEEP HOLE IF LEAKING REPLACE WATER PUMP.FLUSH RADIATOR ,HEATER CORE, AND ENGINE BLOCK. MAKE SURE YOU HAVE 50 / 50 ANTI FREEZE AND WATER.MAKE SURE ENGINE EXHAUST NOT STOPPED UP BECAUSE EXHAUST SYSTEM ALSO TAKE HEAT AWAY FROM ENGINE.

From your description it sounds like your engine is overheating. Make sure you have enough coolant in the radiator and the coolant reseviour. Check your hoses, radiator, and waterpump for leaks. Have your thermostat replaced if it needs to be. If you can't get hot air from your vents when the engine is heated up it most likely means your water pump impeller is broke and it's not circulating coolant.

i am suspecting a flow issue like a clogged radiator or something to do with the impeller on the water pump was there alot of rust? If so that is the impeller and it is in your system real good make sure to flush it until clear water runs out

Changed expansion tank but light still on any ideas 03 ford escape low coolant level light on dash stays lightup


bad low coolant switch or still low on coolant.

Engine Cooling The cooling system components are the:
  • engine coolant temperature sensor (ECT sensor) (12A648)
  • radiator (8005)
  • degas bottle (8A080)
  • radiator draincock (8115)
  • water pump (8501)
  • water temperature indicator sender unit (10884)
  • water thermostat (8575)
  • dual speed fan motor assembly
The water pump circulates the coolant.
The water thermostat:
  • controls the engine coolant temperature.
  • allows quicker engine warm-up.
The degas bottle:
  • provides a location for fill.
  • contains coolant expansion and system pressurization.
  • provides air separation during operation.
  • replenishes the engine coolant to the system.
The fan motor (8C607):
  • operates only when the ignition switch is in the RUN position.
  • will not operate with the switch in the OFF position.
The engine coolant flows:
  • from the lower radiator hose (8286) to the water pump.
  • from the water pump to the engine block and the cylinder heads.
A closed water thermostat returns the engine coolant to the water pump; an open water thermostat allows the engine coolant to flow to the radiator.
Engine coolant provides freeze protection, boil protection, cooling efficiency and corrosion protection to the engine and cooling components. In order to obtain these protections, the engine coolant must be maintained at the correct concentration and fluid level in the degas bottle.
When adding engine coolant, use a 50/50 mixture of clean, drinkable water and engine coolant.
To maintain the integrity of the coolant and the cooling system:

Engine warning light 2004 focus temperature rising


change your thermostat, and your temperature sensor. The sensors can have a tiny crack in them and cause a lot of problems. Once this is done you should notice a difference. Special note, check to ake sure your fan is coming on, and that your water pump is good. Remember if you change your water pump, you must change your timing belt. If you don't you will be replacing them both in under 6 months. Also make sure your coolant is still good.
