Question about 2000 Ford Focus

3 Answers

When I drive my ford focus 2000 se more than 15 miles the air conditioner causes my engine heat gauge to rise high. This overheating issue only happens while using air conditioner. Heater works fine! Also, once the car overheats the first interval of using air, it takes less and less time to overheat again. I can shut the car off and instantly turn back on and the heat gauge returns to normal. What could be my problem? The cooling seems to work fine and there is no strange noises during this occurrence. Thank you

Radiator Fan Relay should be the problem..they had a recall on 01's for it..both fans need to run when the ac is on..more than likely one of the 2 is not working..change the relays

I have a Fortd Focus 2.0 Zetec. The temp guage seems to be a bit erratic. Driving on the motorway it will go into the red section. If I take my foot off the accelerator and lose speed the needle returns quickly to normal then will climb back into the red momentarily and then back to normal. Under the bonnet some water hoses feel red hot whereas the main hose from the block to the radiator feels cool. If I squeeze this hose a few times it gets hot also.theres also a bubbling noise coming from it if the engine is left running.The fans are cutting in regularly also. Could it be the thermostat or something else?

99 ford taurus starts up but doesnt drive more than 10 miles per hour and temperature starts to rise


maybe a coolant thermostat that is faulty, a collapsed or perished hose..

It could also indicate cylinder head gasket/cylinder head problems.

Ten miles is about the correct distance for a car engine to reach normal operating temperature. If your temperature gauge continues to rise beyond normal ..ie. overheating .. you risk causing a lot of damage to your engine.

If you're not sure what to do or look for - get somebody to check it out for you

Did you bleed all air from the system? Is it actually overheating or is the light just coming on? If so, replace the temperature sending unit. If you are loosing coolant with no apparent leak then suspect a blown head gasket which will cause the engine to overheat. A compression test will verify this.

Hi... Be sure to put your heater controls to hot when you bleed the engine coolant, run the engine up to normal running temp and top up as neccessary... you may have an air lock in the heater matrix. Please let me know how you get on....

sounds like your thermostat is stuck open, if its takes a very long time for the engine to warm up and you get nothing but cold air from your heat then thats the first place i would start.

It's 12 degrees outside, how long should i leave the engine of my 2007 ford focus running to warm up?


Wait for the temp gauge to lift off of the low end stop. The car is then warm enough to drive. Be very gentle on the trans for the first 20 miles or so, because the transmission relies on engine heat to warm up the trans fluid. Cold trans fluid is very dense and can cause the transmission to slip, causing gear damage.

2000 focus engine surgeing on tickover


Here is what you need to do, a cleaning of the intake throttle blade and the idle speed control air-bypass valve, they get full of gunk over the miles and cause idle issues (stalls) like yours,
Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake
