I had my Alternator changed yesterday on a Ford escort gti. The battery light was on and temp gauge was stuck past hot. Once changed all was fine but today I started it up and temp gauge is stuck past hot again but no other warning lights or problems I've checked the wires to Alternator and they seem fine so what else could it be I'm female I know a bit about cars but I'm puzzled

The temp gauge and battery light issues may not have been related.
The gauge reads high when the circuit to the temp sending unit is grounded. It could be the gauge on the dash, or a wiring problem, or the temp sending unit on the engine.

SOURCE: '97 jeep cherokee sport reads negative on battery

Have you checked the battery cable connections? If so, check the negative battery cable from the battery to the body and from the battery to the engine for breaks or if they are loose. If good, check the positive wire going to the starter, there is also an inline fuse in the pos. cable to the starter that might have blown. But, my guess is that the battery cables are loose. Hope that this helped, good luck. Let me know how it went. I'll be here if you still need me.

SOURCE: new battery caused 'Battery" warning light to light? alternator?

I also have an ES300 and have replaced the battery. There are a few things you can check first. If your battery was really that corroded you might want to replace the battery terminal connectors with new ones. If they are loose(able to turn them with your hand, even if it requires a lot of force you should not be able to twist them with your hand) it could affect the alternators ability to charge the battery if its not making complete contact with the battery terminals. If you tighten the connectors all the way and can still hand twist them, then its time to replace. If the old terminals are fine you would at least need to clean them thoroughly due to the severity of corrosion from the previous battery. If its not charging the battery at all you might want to check the alternator fuses. Thirdly, a loose alternator belt can also cause the alternator to put out less volts, therefore not supplying enough power to run the necessary accessories causing the battery to be used while the car is running instead of recharging it from the jolt of juice it lost starting the car.. If its loose you can have it adjusted and tightened, if the belt is cracked or worn, have it replaced. Make sure to check that the wiring is all sound and not broken or corroded that connect to the battery. Make sure the ground wire is still grounded. If these things fail to solve the, it might be time for a new alternator. If you have autozones in your area they will run a free alternator check for you. Just go in and ask for one and they'll wheel out the machine to your car. (P.S. If your running any kind of additional electronics like an aftermarket amplifier or any other high drain device you'll have to install a high output alternator to accommodate the extra demand. A new alternator putting out the factory level voltage won't be enough even though it's brand new. Those can be obtained off of eBay.)

SOURCE: 1998 Ford Escort dashboard warning lights and gauges not working.

Sounds like possibly the ignition switch is going out. Try jiggling the key in the ignition in the on position and see if your lights come back on.

1993 ford escort heater blowing cool


heater core cloged, get car hot check heaterhose going into heatercore should be two inch thick hoses going into the heatercore, underhood against firewall pasenger side, after hot while running heater on, chech to see if both hoses r hot, if one is cold,that means there is a restriction in the heatercore, sometimes on older cars there is a external valve run by a vaccume hose, or cable, thats fixed in with the heater hoses , sometimes this valve jams and can be manually switched.

My 1998 expedition overheated yesterday (gauges did not indicate hot). It smoked and when it cooled down I put coolant in and today when I went to drive it was not wanting to accelerate and the rpm dial...


The reason it did not read hot, on your temp. gauge, is cause your temp. sensor read's coolant or water temp only, not air, if cooling system is empty, coolant temp. sensor will not read, like an air temp. sensor well, more the likely there could be a coolant leak for cooling system to be empty, also could have damage your cylinder's head's, need to have a block test and cylinder compression test done to fine out if head's are damage.

Battery light stays on


Not related as one is water system and other is electrical,As far as the heater goes make sure the heater core is not blocked by removing hoses from firewall and flush the heater core with a garden hose to make sure its flowing freely.Also check that the heater tap is working,the tap is in the engine bay and turns the water flow on and off when controls on the dash activate them.Check that the cable hasnt slipped on the retainer clip or come off the back of the heater controls.As to the alternator light,check that the single wire that pushes into the back of the alternator is intact,not fallen out and undamaged along its entire lenght.Its not a wire thats bolted but the wire with a round terminal end.Check all electrical connections Good luck

M reg 1.6 zetec escort high emissions


you say the temp gauge doesn,t work could it be possible the thermostat is stuck open which would mean the engines running cold which means the auto choke won,t knock off normally if you short the temp switch wire to ground the gauge goes straight over to hot if it does,nt then the gauge is faulty but its usually the switch as far as the high c/o it could be as stated above or some thing as simple as an air cleaner c/o should be under 2.5 these carbs weren,t the best when they came out which type is it if its the v v i would get it overhauled
