Stuck Thermostat – Diagnostic consultation and Engine Carbon Clean on Vauxhall Astra 1.8 petrol (2008 – 104,910 miles)

⚠️ Thermostats do an important job at keeping engine temperatures at just the right level so the engine is at peak fuel efficiency.

️ Misbehaving thermostats can lead to no end of problems (and unless you know what to look for will go unnoticed as they typically don’t trigger diagnostics codes).

❄️ A cold running car will be inefficient and create higher emissions (making a car get dirtier quicker, using more fuel than it should and if a diesel with a DPF can stop the regeneration process).

A hot running car may well overheat if the radiator fans can’t cope.

Here we have a Vauxhall Astra 1.8 petrol (2008 – 104,910 miles) booked in for diagnostics and Engine Carbon Clean as part of a multi-vehicle booking.

Initial inspection noted the radiator fan running continually which alerted us to a potential electrical issue or temperature issue. Initial diagnostics confirmed a code for coolant thermostat valve stuck.

Live showed the radiator fan was just about keeping things under control for now with temperatures constantly 95°C and over.

‍With the above documented and discussed with the owner then we agreed to proceed slowly and keep an eye on the temperatures. On with the clean and slowly and surely the engine smoothed out, quietened down and thankfully the engine temps stayed steady, but hot. The owner can now get the thermostat dealt with.

Adrian is a lovely fella, explained the process, carried it out well, clearly done exactly what it needed to do as I blew a load of stuff out the back when I drove it after. Will definitely be coming back in the future.

Steve arrived to give my Jaguar xfs an engine carbon clean. Presently on 107,000 miles. Explained the process and was obviously very knowledgeable about the process and expected outcomes. And he was a thoroughly nice chap.
The V6 in the xfs is a quiet, smooth, powerful unit and I was not sure of what improvements I would get. Well, I’m impressed. The power delivery is smoother, the engine even quieter and 6 mpg better to boot.
If you want to do one thing to maintain and improve your motor, then this is what you should do.
Had the pleasure to meet Adrian this morning who performed a carbon clean on my bmw 525d
Very knowledgeable guy, I was really impressed.
Car drives much better now, highly recommend.

Thanks Adrian

Leon came out to my car about a month ago. He was brilliant, he did some diagnostics, asked some questions and then got to work sorting out my problem. He was extremely thorough and I could tell he genuinely cares about providing a first class service. Fantastic!

Iv had the pleasure of having 2 Carbon cleans from both Adrian and Mark. Both lovely gentlemen and you can tell they love what they do. My car failed on emissions and this helped me get the car through the test, and at the time, I REALLY needed a pass because I couldn’t get anywhere. These guys saved me. Not only that, it’s a lot cheaper here compared to other places also. Thank you so much and look forward to seeing you in future endeavours.
