Overheated Hyundai Atos

We received a case of a overheated Hyundai Atos last week. Kinda weird case actually as the owner initially suspected the water pump leakage. During checking, we didn’t found the water pump seems to be the culprit.

Hyundai Atos from Hyundai Motor Company, were one of the best seller compact car here in Malaysia in the year of 2006. With wide luggage area and high-roof interior, does attract local family type driver to own it. Roomy, versatile and fun, the car that was design and built for families.

A 1000 cc micro MPV with a heart beat of a 1300 cc car. An evolution from Hyundai R&D Center which maximizing on dynamic performance. Spacious and comfort, the paramount importance in the creation of this car emphasizing on headroom and legroom.

In Malaysia, Hyundai Atos is locally assembled by Inokom carrying the badge Inokom Atos. The Inokom Atos Prima was later introduced in 2006 which has the new Atos Prime front while maintaining the original Atos rear.

Initial Checkup

As what we’ve been told by the owner, he suspected the water pump were leaking. Taking into account of what he heard from his fella member that caused might be coming from the water pump leaking problem. That’s sound easy. We just need to change the old water pump with a new one and job done!

But we are not like that. Simply change something that we aren’t sure enough the cause of the problem. If it can be fix, we’ll fix it!

The Culprit

After a thorough checking, the problem seems to be caused by a leaking in water hose that runs in/out into the thermostat housing area. We can see that the leakage has leave its corrosion mark marking it has been leaking for sometime now until it can hold any much longer and explode! (That’s what the owner heard). Kinda tricky to look onto since the small engine bay and the full pack component stack on each others.

Need to squeeze through here.
Taken out the spark plug cover. Next: take out the ignition coil.

The real culprit! Shoot! The small hole that really to be the major problem.

 

Medication

There are two options for now:

  1. Change the thermostat housing to a new one.
  2. Repair the leakage area.

The owner then decide they wish to repair it first until further action discussed. Next, we’re on to the process of repairing the thermostat housing and need to get the engine up and running again.

Clean up the corrosion mark.
SteelStick Epoxy comes in handy with this kind of situation.
Done sticking the SteelStick to leakage hole.

The overall process takes around 1 hour to completion and the car is still running up till today. The next step is the owner should replace the thermostat housing as it wont last long with that much corrosion coming out from it.

  1. Hi pomen yala. Im plannig to buy this atos inokom year around 2006 / 2007, its a second hand car because its kindda cheap, and reosanable price. So the question here, what terms or part that i need to check wether it is in good condition and how was the sparepart? Is it easy to get yet expensive or how? Compare with kenari in the year..i need some advice….tq! 🙂

      Hai Shema.
      If you are considering between Atos and Kenari, our personal choice would be Kenari as both have similar specification in terms of handling, spacious, sort of mini van “kind of”, better fuel consumption in it’s class. However, Kenari would be best bargain for since it is a locally made and most of the parts available in almost spare part shop nearby.

      Either way; when choosing a used vehicle, certain things need to be consider such as:
      1. Is the car bee involve in an accident before? – look onto the chassis in engine bay, under carriage, and pillar for sign of welding job.
      2. Run the engine for an hour or at least for 30 minutes – check for oil, water, fuel leakage in the engine bay.

    • pls choose another car viva maybe not theses korean cars barang mahal cepat rosak i have already spent 4.5k on my Atos due to mainly overheating and still problem not solved!!!.
