Overheating in Opel Vectra: experience and repair tips
(Translated from German)
Summary of the thread
An Opel Vectra is experiencing overheating and low coolant levels, potentially due to a faulty radiator shutter. A similar issue in another vehicle was resolved by replacing a corroded wiring harness to the sensor, which was time-consuming but effective. Suggested solutions include checking for leaks, inspecting the radiator and hoses, testing the thermostat, and seeking a second opinion from a reliable source.

Hey, thanks for your reply, that sounds like the exact same problem I'm having now. How expensive was the whole repair for you back then if you remember? And have you had any other problems since then that might be related?

Hey, no problem, that's what we're here for. Well, at the time it cost me €155 to repair the corroded wiring harness to the sensor. Well, I thought the cost was pretty high too. But since the workshop visit, I've had no more problems, especially with the radiator shutter, which is now running like clockwork again. So, it was definitely worth it! Just spend a few euros and you'll be able to drive relaxed again. Believe me, it's better than constantly driving around with the fear that the car is about to overheat! So, keep your head up and off to the garage - you won't regret it!

Thank you very much for your encouraging answer. I was a bit worried about the cost involved, but if it is then it seems worth it. I also can't always drive with the worry that my car might overheat at any time. I will definitely take your advice and get a garage appointment as soon as possible before it gets any worse. Thanks again for taking the time to help me out. Nice conversation!

Your Opel Vectra's overheating and low coolant could be due to a radiator leak, faulty radiator cap, thermostat issue, water pump failure, or hose problems. I would check for leaks, inspect the radiator and hoses, test the thermostat, and consider a second opinion from a reliable source. Best of luck!

I have a similar problem, can you tell me how to check the thermostat?

Hello, I had a similar problem a year ago with my Astra H (2008, diesel, 140000 km). At that time, I also had signs of a constantly overheating engine and a low coolant level. Well, and guess what, there was actually something wrong with the wiring harness to the sensor. The thing was totally corroded and had to be replaced. The repair was basically quite time-consuming, but the guys in the workshop did a good job. So have it checked at the workshop. Don't worry, a corroded wiring harness like that can be repaired. Just next time you have a problem like this, don't wait too long to get it fixed. It can lead to even bigger problems if not addressed in time. Have a good trip with your Vectra!
