Where is a/c drain hose on 2003 hyundai elantra gls

Question edited for clarity.

Possibly, some do cover things that affect starting, the 'fuel pump relay' for instance. You need to diagnose, not just replace as a guess. Check for codes. A prograde scan tool will diagnose all modules and relays.

Under the car, at the base of the engine bulkhead on the passenger side.

WHERE IS AIR CHARGE TEMP. SENSOR LOCATED ON A 2003 HYUNDAI ELANTRA

it can if you have the proper tools and a little patience its not very hard at all it may be a little snug i cant remember off hand where the starter is located on that car but its relatively an easy fix.

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

Hi:
If you follow your upper radiator hose back to where it attaches to the engine, that is where the thermostat is located. it is called the thermostat housing and it is held onto the engine with 2 or 3 bolts. If you purchase the thermostat from an auto parts store, they often can give you some specific guidance too. Of course, you need to start this project with the engine cold, and first drain the coolant out of the system. Make sure you have a new gasket or sealant to install teh new thermostat too.

Two seperate problems. I would say you have a bad wheel sensor. A trip to a local big chain parts store will tell you. They will run a diagnostic and pull the code for free. Hope this helps...

(1) No need to know if engine block coolant drain plug was available. Once the water pump was removed, all engine block coolant was drained. (2) After removing the three engine mounting bracket bolts, I also removed the mount bracket from the the body and made enough room to replace the timing belt easier.

Very wild guess. I replaced the bearings in my 2003, and was looking in my tool box. I came across a 1 1/4" socket that I purchased around the same time, but I realize that it should be the metric equivalent of this, so it probably did not fit perfectly. Metric conversion would be 31.75 mm.

what u do is go to your local auto supply store and buy throttlebody cleaner you remove the rubber hose from the throttle body with the engine off of course u open the throttle and spray cleaner in it then use a tooth brush inside it replace the hose done
except it will be hard to start the first time crank engine over with foot to the floor on the gas pedal do not pump it
