Engine Overheating

[Luckcent]

If you want to change then you must know where is the drain-plug. When doing the change only when car's engine is off.

Hi there, I'm not a chevy driver, but got into the same problem as you. It turned out that my fan controller went "ka put". you may want them to check the fan controller.

 

BTW, do you put the air con all the way to the coldest and control cabin temp by fan speed? If not, it could be the cause as more than 5 friends had problems with overheating because they set the air con at > 25C and ended up the A/C turns on and off frequently, screwing up the car's whole cooling system.

 

Just my personal experience, hope it helps.

thanks. maybe I will have to ask for more info on that when I go for my next service.

[Luckcent]

Dont need to wait till next sevicing. Can always open hood to check for yourself. Just look at the coolant resevoir closely and you will find either on the bottom or at the low side of it.

I din say that leh... think Jagash mentioned it.

 

for car to overheat, the major components are pump, belt, fan and radiator...

Like what you said the radiator cap is faulty or the radiator fan is not woking.

 

[Wenwen]

ok.. will check for that tomorrow morning. as it is my first time owning a car, maybe will get my friend to help me with that..

[Luckcent]

Aiyah mixup liao. The reason should still be the same......

[Luckcent]

Also ask your pal to help show you how to check for engine oil level too.

[Wenwen]

hee hee.. that is a bit easlier.. I can do it myself.. ..

 

have to check it every two weeks according to the service people.

Sure you saw the right thing? One fan belongs to the A/C and the other one belongs to the radiator. There are 2 fans and the radiator has enough space for only one fan.

 

FYI, the A/C fan blows much stronger than the radiator fan . Strange but true.

[Genie47]

You don't disable the radiator thermostat! Your engine will cool too much and will affect your FC. Not to mention damage the pistons. You disable the thermostat that controls the fan. Let the fan run continuously.

 

The bad thing about this is that the fan will die much sooner than usual.

Hi Genie

 

I am in the Opel delphi forum and you wrote me before there welcoming me as a new aveo owner (getting my sports blue 1.4A notch anytime this or next week).

 

Do you know if the aveo is using the x or z engine similar to the Opel astra or corsa's engines? Asked Starauto sales peole and they do not know.

 

If they are indeed gm engines, the x uses the green coolant while the z engine uses the orange coolant.

 

GM engines do not, repeat do not drink other types of coolants as they are developed specifically for themselves. Other brands may not cool at the correct temp ranges have different anti corrosion properties and may even course pitting on cylinder walls. Of course, wrong gm coolant for the two types also cannot.

 

I learnt this in my opel vectra b (X engine - green coolant), Corsa c (z engine orange coolant during our talk with the german expert, mr Dieter whom they flew in twice to do free inspection and consultation.

 

Of course my more learned buddies at the Opel forum had more details on the 2 engine types.

 

Tks, hope to meet you guys at Kallang this Sat if I can make it although I have not collect my car yet. Will definitely be keen to join you all in horn changing.

[Genie47]

Yes, GM and their crazy coolants. To me orange coolant = Dexcool = Deathcool. The green coolant is so much better according to many GM users in the US. Their cars are mainly the 2.2L Ecotecs AKA Vectra engines.

 

If I'm not wrong the engines are X engines as in X14XE equivalent for the Aveo. Basically, the Aveo shares the same engine block as the Astra 1.4L. Only the management, intake and exhaust are different. It think the piston setup is slightly different as the Aveo has a CR of 9.5:1 while the Astras have 10.5:1. This I believe gave us our pretty poor low end compared to the Astra. We can use RON92 gas compared to the RON95 minimum that the Astra needs.

Yep, of course I saw the right thing. They only had the radiator fan in the test drive car. I still can't believe the bulls*%t explanation SA tried to give me when I questioned them

 

This is my fourth continental car(well, I guess you can call the aveo continental huh ) and nothing escapes my attention.

 

Yes, the a/c fan blows much stronger than the radiator fan simply because it is larger than the radiator fan! And in our climate, this spells trouble for those who constantly get stuck in traffic jams.

[Silver_blade]

I really hope it's not due to design fault. Hope it's just a matter of using the wrong type of coolant.

YEs continental CAR

Yup Ok , its the thermostat that controls the fan and not the radiator side....
