Question about Ford Focus

2 Answers

My 2001 Ford Focus (Zetech) overheats when going uphill for long distance (2 km uphill).All off a sudden it will shoot to near red zone for a short time then back to normal when I slow down or run at flat surface. when the car is in park or i could leave it on all day and at normal surface street speeds the temperature would be normal and it does not overheat I have changed the tehrmostat and the led of the water bottle. but still the same problem. I have checked the water pump and it is working fine. I can drive inside the city for hours and temperature remain normal. I noticed that when i turn on the heater it doesnt blow out really hot air is more like slightly warm air with smell like antifreeze smell . while the water level in the waterbottle stay constant with time.

You are leaking coolant somewhere. Are there any wet spots on the ground when the problem occurs?

Ford Fiesta Zetec engine, year 2000. overheats after getting up to temperature, stays on normal for 1-2 kilometers, then gauge shoots over to the red. I stop, can hear water bubbling, wait till it cools...

1. Check the radiator cap.
2. Check the reserve tank, whether water level is maintained or getting filled. If it's getting filled, there should be a leak in the radiator or gasket

You can look up the recommended spark plugs for your vehicle in the owners handbook. If it is not available, you can go to the various spark plug manufacturers Websites (Champion, Bosch, NGK, KLG) enter your vehicle particulars and be provided with the correct type.
Try putting some Injector Cleaner (from the auto parts store or gas station) into your fuel tank to see if that helps with the rough running. Follow the instructions on the bottle.

Dash temp guage goes to red on 2000 ford focus dohc zetech

Because you have done so many repairs already I would most likely say that the gauge is defective. I would use a manual temp probe and probe the coolant temp after the car has reached operating temp. Coolant will be between 180- 230 degrees. If coolant temp checks out and you can see coolant moving in radiator and the vehicle does not overheat then you will need either a gauge or a coolant sensor. To locate the sensor it should either be mounted in the thermostat goose neck housing or the intake manifold.

Are you actually getting less distance between fill ups? The dash display relies heavily on driving style.

It very much sounds like the head gasket. Just one thing though. Has the timing belt been changed? If so recheck timing as one tooth out will cause this problem.
