Overheating SolvedSolved

Chevrolet Optra 2009  118000 miles
Good night, I would like to share my case with you. Some weeks ago, after driving around 25 miles at 75 mph, I stopped when passing by a police check and the air compressor turned off. Two minutes later, it started working again. This failure was repeated 4 times in the same week. The fifth, I noticed an engine temperature increase. When checking, I noticed that there was a small leakage in the plastic connetion that leads to the thermostat. A copper junction was installed and the missing refrigerant was added. The temperature sensor never reached 100%, I always stopped at 75%. The failure con… Read complete

Hello, probably your thermal expansion valve is damaged. Any air conditioning technician should be able to solve this problem without charging you too much. Good luck.

Thank you for your comment. I would like to share how I solved it. Even though the car always had refrigerant since leaving the agency, the radiator was too dirty. It was cleaned but it was necessary to replace the superior and inferior tanks because they were considerably obstructed. Even more, the refrigerant reservoir was replaced as it was left useless after moving the hoses so much. Luckily, the car started working properly again. Thank you very much.

Starting SolvedSolved

Chevrolet Optra 2006  300 miles
Hi everyone. This is what happened to my car. Two days after repairing the whole engine, the hold light started blinking on the dashboard and the battery got damaged. I changed the stop neutral sensor myself and removed the battery for it to be repaired. When installing it back, a noise of a short circuit was heard, even though there was no smoke coming out from nowhere. Since that moment, speeds have no longer been indicated on the dashboard and the car has not started working again. Even though the engine starts running, it won't finally turn on. I've already changed the crankshaft sensor but with no positive results. Hope you can help me solve the problem, thanks.
