i just replaced the timing belt, and asked the garage to look at the transmission for me because i thought i was experiencing some subtle shifting problems. they told me the transmission looked fine, but i needed a new filter and fluid. the engine light didnt turn on til a couple weeks later tho. does this sound like a new filter and fluid would fix this problem?

SOURCE: AC works, Heater not working, 2003 Hyundai Accent.

Check the coolant level, do this with a cold engine. Or if you have recently used it. let it cool down for about 25 minutes before removing the radiator cap. if it is low, refill with coolant. If it does not, check your thermostat. Or better yet replace your thermostat. Be sure to get the right one . the same degrees as your old one. Just ask the teller to give you one for your engine size and car Model.And year.See where the radiator cap is. Then drain some coolant to where it will not spill from the radiator cap. Remove the hose nearest the radiator cap and you will get to the thermostat housing. Remove the housing and note how the thermostat is placed. Take of the thermostat housing and the old thermostat. Clean the housing and around the hole where the thermostat goes of any deposits. Get some grease and cover the new gasket with grease on the housing to hold it in place. replace the New thermostat and make sure it is flush with the engine and the housing. If it is off , you could break the housing upon tightening the housing.replace the hose and refill with coolant slowly to eliminate any air spaces.. Also check the coolant reservoir and fill it to the indicator line. Restart the car and chek for any leaks. Then check the heater after the engine heats up. If that does not do the job it could be the temperature sensor or the heater core.The heater core will take more time to check and clean or replace.

Did you use a aftermarket O2 sensor or a genuine Hyundai one? If it's an aftermarket one it may be bad or not as good as the OEM one. See here for more details and other potential causes: P0133

The ashtray light should come on automatically on a Hyundai Accent when you open it. If it is not coming on you could have a blown bulb with any auto parts store carries for around $1-5.-------------------------------------------------------------------------------------------

Engine Check Light


you should have the code read and go from there. You must realize sometimes it is like an early warning for things to come so it is best to know what the code is causing lightt to correct the problem.there are several things which can cause a light without effecting running condition. But if you let it go it may cost more further down the road.

I have hyundai accent 2003. While driving the engine died. Checked fuses,ignition,fuel pump(don't know if the pressure is right),starter is starting ok.


#1. Scan for trouble codes. If any, record them and let us know which ones they are.
#2. Connect a fuel gauge to the fuel delivery line at the engine... try to start the engine while monitoring fuel pressure... if there is fuel pressure (approx 35 to 50 lbs), the problem is elsewhere.
If no fuel pressure, check fuel pump relay, fuse, wiring to fuel pump connector (power & ground - use 12volt test light). If power & ground are present, problem is the pump (fuel filter is attached to the fuel pump inside the tank).
#3. Check injectors for injector pulse, check ignition coils for spark to spark plugs.
