ok so i just refill my reservoir again to full, no leak but engine is overheating every 300meter, i shut down engine n wait like 30sec and it went back to middle temp and drive off and it repeat everytime...wtf going on?
Thanks for replying to my post regarding my Glycol oder issue.
Your problem may be the same cause as mine but is obviously much worse.
I am very much intrigued however as to why the problem goes away after such a short period of time of you turning the engine off. I find it hard to believe that the engine is truly over heating as such a short engine off period would not be long enough to allow an over heating engine time to cool down.
Recommendations to have the dealer look at it are strongly supported by myself.
In the interim, I would start with these steps. 1st Is the car setting any diagnostic codes with the service service light being illuminated? 2nd Is it actually over heating or is the temperature sensing unit sending a false signal to the ECM? If you have a hand held Infrared Thermometer point it at hoses where the collant enters and exits the engine. The coolant should be at or maybe "SLIGHTLY ABOVE" the boiling point at the exit point but noticeabaly cooler at the exit point of the rad. If the coolant is not noticeably higher than the boiling point then I would focus on the temperature sensor. 3rd Are the rad/cooling fans cycling on and off. They should cycle on once the engine progresses past a normal operating temp then cycle off once that temperature goes below that point. Just know as well that as the AC compressor cycles on the fans will also cycle on to increase the airflow through the AC condenser which is located in front of the radiator. 4th If the coolant is heating up it could be a variety of reasons. Some as simple as a poor thermostat, poor rad temp sensor thereby not cycling the fans when require and more serious challenges like cracked head/engine block.
With you actually losing fluid I sadly would think your problem may be more on the serious side.
Having said that I would STRONGLY recommend that you have both the glycol and engine oil independently analyzed. Catapiller Industries in North America have what they call the SOS program. A person can go to a Catapiller dealer/service and buy a kit that contains an envelope and a fluid sample container. This program is designed soley so that customers can find out that things are inthe process of getting serious. It allows owners to fix things before they experience a never convenient catastrophic very expensive failure.
Collect the fluid, return the sample to Catapiller with your contact information and in about a week you will get an email with an in depth chemical analysis of the fluid.
The big thing you are looking for in the report is the presence of engine oil in the glycol and even more problematic is there glycol in the oil.
Even microscopic amounts of each being in the other is unacceptable and points to a serious internal problem.
The kits are about $25.00 per kit here in Canada.
I have in the past found the information to be great value particularly when I suspect the dealer trying to play the smoke and mirrors game.
On a side note, I trust you have read on this posting of the experience of another owner where the clamps on the rad tanks failed leading to a major coolant fluid leak.
Best of luck in your quest.
Please do continue to post the specifics of your case and resolutions Kia has employed.
