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.
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!
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.
There are two options for now:
- Change the thermostat housing to a new one.
- 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.
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.
