Tip & How-To about Hyundai Accent

Draining of car battery charge

My tip is for all makes and models of vehicles
It is a common fault these days are more and more extra fittings are loaded to the cars and when proper precautions are not taken it will end up to fault the system.
Hence in case of a battery drain overnight try these checks.

You must check the drain current on your battery after the engine is switched off. The best way to check this out is to connect an ammeter in series to the battery and check. There can be a permissible limit of few milli amps but a large drain can in about 12 hours ( overnight) fully drain the battery no matter how much you have charged it or the system charged it up.
Now disconnect one by one the circuits to centre on the faulty circuit and then the faulty device. This is easy as the fuse can be pulled out one by one till the ammeter reading drops down.
Now it is always possible that directly connected circuits like Clocks, audio/video systems, remote control units , brake lamps park lamp circuits can be possible problem areas.
After the device is identified and battery must be charged up fully and tested overnight.

when I switch to defrost setting the A/C light comes on and then starts raising the temp of car over 200 When I turn the switch to front face heat light goes off and goes back to normal range.

This indicates a cooling system restriction. The A/C will normally come on with the defroster; this is to dehumidify the air to the windshield, thus preventing fogging. But this also adds an extra load to the cooling system since there is heat that needs to be removed from the condenser, which is in front of the radiator.

There are a few possibilities for the problem.

  1. There could be low coolant in the cooling system.
  2. Thermostat could be not opening fully.
  3. Cooling fans may not be operating properly. Electric fans must run constantly whenever the A/C is running.
  4. There could be a partial clogging of the radiator
Obviously, you should check the obvious problems first. They are easy to check and cheaper to fix. Since you are not giving the exact make, model, and year of vehicle, I can only talk in general on the possible faults. But if the vehicle is older than 7-8 years, the radiator could very well turn out to be the problem. They corrode and clog over time, and what happens is they manage to do OK until you add the extra heat of the A/C, and then you see the start of the overheating.

are 2005 LaCross rims proper fit on 2004 LaSabre

THe items here to check are stud dia and pitch All studs fit in the center of the holes. Next check that the rims when fitted miss the brake calphers. Next check for rim off set. How far the rim extends past the center of the bolt plate . If it is to the outside it places extra load on outer wheel bearins causing premature failure and too far in will rub on chassis parts. Check with a tyre dealer for accurate advice as if you fit the incorrect rims you will violate the safety code for the vehicle.

i have a toyota fielder 2007 with 1.8 engine. its starts perfectly in the morning. but during the day when i press the button it usually takes very long to start around 8-10 seconds. or atleast i have to press the button twice or thrice.

Hi Cookie, These vehicles are often fitted with the new D4 Direct injection engines. I would suggest you take it for a diagnostic scan. A very common fault on these vehicles is the high pressure unit fitted to the engine becomes defective. Another is the injectors becoming fouled. I will not be surprised if the scan shows a defective temperature sender unit which is responsible for enriching the engine fuel supply during start up. Regards John

Regarding the timing, I would advise you to get the fault codes read using the on-board diagnostic system. This will point you in the right direction. It might not be the timing at all but one of the sensors either not working, or not connected properly.
As for the lop-sidedness, I'd suggest double checking that the engine mounts are all present and correct. Did the recon engine come from your own vehicle or another one, and if so was it the same model?

Hope this helps. If this "fixes ya", I'd appreciate a rating for my reply, If not, please delay the rating and add a comment with any extra info you have and I will try to think of something else.

Cheers, D.
