My i30 Standard 96' is on 130,000KMs (80,000Miles). I got this car on Jan 1, 08' when it's on 70,000KMs (43,000miles). I took it to a Nissan dealer once I just got it, they replaced rear O2 senser, repair CAT thread, changed engine oil & filter. Ever since then, the car has been done oil changes every 3000~6000KMs, and most of the times I used Castrol Synthetic oil. It has been running well.
Yesterday, I took it to an Infiniti dealer and had transmission fluid flush done. They also cleaned up everything under the hood to make it look very clean and nice. I drove it back home, no problem. This morning, after I drove it for 20 minutes, coolant steam came out from under the hood. I pulled over, cooled down, opened the hood, saw coolant container was empty, but the radiator still had coolant. I had no idea where the coolant leakage coming out.
I then towed the car to the Infiniti dealer right away. They told me the problem had nother to do with their service yesterday. I was told it was the radiator problem and the thermalstat needed to be replaced as well.
In addition, they took me under the car. I was showed engine oil leakage, CV boots oil leakage. They also told me A/C did not work either. To fix them all, parts alone are CAD$1700.
Questions:
1. Could flushing transmission fluid cause coolant steaming out? Or it is just a coincidence?
2. Is it normal to see engine oil leakage on i30 at this age? How can I confirm it is actually engine oil leak?
3. Other thoughts?
Thanks
Jack
