Radiator coolant overflowing in Chery QQ
Davy replied to Uditha Bandara's question in Mechanical problems
What exactly do you mean by overflow? Doesn't the car have a coolant expansion tank? If not, is it possible that the expansion tank was damaged and discarded following the accident? It's normal for coolant to overflow into the expansion tank (it's actually an overflow tank as pressure relief happens at the radiator cap in most cars) as the pressure inside the system increases. When the pressure goes back down as a result of the engine cooling down, the vacuum created results in the coolant in the expansion tank being sucked back in. For this to work properly, the radiator cap needs to have the proper pressure rating. Also, by wiring the cooling fan to direct power, whoever did that job was basically addressing the symptom rather than the problem itself. Your car is meant to work at a set operating temperature. Too cool is as bad as too hot. -

Wait what? That's you?? Oh it is frowned upon in all corners of the Internet. Do you remember what happened tk the last guy who was using multiple profiles? @MADZ, what are our options here? Can we deactivate @Sir Lancerlot and rename @Hyaenidae to be @Sir Lancerlot? Ane manda bung... You and your fancy names. At least now I don't have to look at your username every time I mention you to make sure I've spelt it correctly.

OBD II diagnostic - unable to connect ECU

@Sylvi, please be mindful when posting new content. You had made your most recent post in an unrelated thread opened in 2006. I have hence moved your post and responses here. Thanks!

Thought it was strange because I have't heard of the issue on the EX from others who've had early model cars which are now more than 10 years old. Knew that @Hyaenidae's car is a later model (2014 from memory), so this prompted more questions. My car, although it has different, stiffer suspension, is a 2011 model and the boots and stuff looked brand new when I swapped them out to switch to coilovers in 2018. Yes Melbourne is a lot less humid than Sri Lanka and the car's undercarriage has never been washed (I do use my pressure washer to wash the wheel wells thoroughly when washing the car), but I believe shock boots last several years before giving way. Just looking at the photo of the boot again, it looks like your shock is already leaking @Hyaenidae.The inside of the coilspring is darker and has gunk stuck onto the spring due to oil being squirted from the oil seal of the strut. Maybe it's water that's not dried up, but better run your finger around the oil seal to see if there's a leak.
-
Strange. I wouldn't rule out other things like service stations using harsh chemicals (like kerosene) to wash the undercarriage and wheel wells. Or if you or your regular car wash place use a chemical that degrades rubber.
-
Maybe it was badly adjusted? If it was an issue in the quality of rubber, I would expect all boots to have similar kind of wear. Is this the left side?

Disconnecting the battery on a car with an EFI engine causes the ECU to be reset. This throws the fuel trims and stuff which contributes to the rough idle. The ECU takes a while to re-learn and let the engine run smoothly. If the car has a factory fitted navigation unit, the map data might be cached in the unit's memory which is volatile. If this is the case, disconnecting the battery without a backup erases the memory which will cause the unit to show the "Insert Correct Map Disc" error. Other obvious things that get wiped are your fuel consumption stats, mileages, radio stations, and other settings depending on options in the car. So no, it's not just hybrids.

Hi Christy, welcome to the forum. You did the right thing by running a scan before determining the issue. Do you still have the Check Engine light on after the repair? If yes, there is still an issue that the ECU is detecting and preventing your car from idling and accelerating. If the Check Engine light does not indicate anymore, then it could be due to the ECU not being reset after the new Oxygen sensor was installed. You'll have to keep the battery disconnected for a while to allow it to reset. If that also doesn't solve it, get your ignition system checked out.

Not sure if the excessive cooling fan noise is normal, but they emit quite a bit of noise at high speed. It can get worse if the sound absorption material under the bonnet, or if the plastic engine undertrays are missing. As for #2, if the temperature gauge is showing normal, then you don't have to worry about it. You can't really tell that an engine is too hot simply by "feeling" the temperature. Since it's a second hand car that's over 10 years old, I suggest doing some preventive maintenance like changing all fluids, getting a fuel system clean-up (tune up) done. Especially if there's no verified maintenance history.

Looks amazing! Good to see them in their natural habitat!

You have a check engine light. Get a diagnostic scan done to find out what the error code(s) is. I've learnt that a bad 12v battery can contribute towards warning indicators, so while you're at it, get the 12v battery checked as well.
-
If the issue is carbon deposits causing the TPS to give incorrect readings or the IACV to get stuck, you might be able to get them cleaned with circuit cleaner, properly dry them and reinstall. In the mean time, make sure that vacuum lines have been properly reconnected after the tune up. It might be something as simple as a vacuum leak under compression.
-
Did the mechanic who did the tune up clean the throttle body by spraying throttle body cleaner directly onto it while the Idle Air Control Valve and Throttle Position Sensor were still plugged in? If yes, my guess is that your TPS or IACV has taken a hit. Get the TPS tested and IACV inspected visually to make sure it goes through its full range of motion when power is applied.

@Mohammed Azeem, are you looking for parts for your Lancer? Which parts are you after?
-
The diagnostic scan shouldn't cost you much, so better take it to the agent if possible. As I said before, the cost of repair comes down to what the actual issue is, and will only be revealed from the errors that are found during diagnosis. Not sure of other garages, maybe another member can suggest one. I assume the agent would have Honda Specific equipment that enable them to scan and provide you an accurate report of what is wrong.
-
Only a diagnostic scan will tell. On the plus side, the car "knows" that something is wrong with it and telling you. This is better than an error that is difficult to identify. You say that you bought the car recently. Did you import the car yourself or buy it from a car sale? If it's the latter, did you get some sort of warranty? If yes, you might want to take it to them for inspection.
-
From the warning symbols, the errors are in the following systems in order of the photos in your post: 1. VSA (Vehicle Stability Assist) system 2. Hill Start Assist system 3. (Electronic) Parking Brake 4. Braking system The warnings are basically telling you to get the above checked out. Get a diagnostic scan done to reveal the exact error codes and proceed from there.

She hasn't aged at all mate. Still looking mint. And that paint job... damn. I want to paint the roof, bonnet and front bumper of the Mazda as they are showing signs of age. This inspired me to do it. ? Labour here is so expensive though. I reckon it will cost me quarter of the price of the car to give it a full paint job.
