C1/107/Aygo - Fitting an engine temperature gauge

In today’s video, I’m installing an engine temperature gauge. This, in my humble opinion, should have been something the car came equipped with from the factory, but I guess they were designed and built on a strict budget, given the type of car it is. I’m installing it because it’s a good tool for health and monitoring f the engine cooling system. It can help on a day to day basis to make sure the engine is warm enough to turn on the de-mister heater and it’ll help early diagnosis of a cooling system problem by showing the engine temperature increasing. That’ll give you the ability to spot the problem and pull over, before it’s too late and you’re on the side of the road with an overheated engine.

I did have a couple of problem during installation, but they’re entirely of my own making. The first one was the pipe adapter for the sensor installation. Like an idiot, I had measured the OUTER diameter of the radiator pipe, rather than the INNER diameter. One Amazon Prime order later and that problem was fixed. The second problem was that of a power supply issue to the display gauge itself. I have tapped into the power supply for the volt meter next to it, but that appears to have an issue with the relay that provides the power on an ignition switched supply. I resolved this after the video went live and the gauge now works a treat. During installation, I measured the resistance of the sensor when cold and then again when hot, so I’m confident that the sensor is transmitting the correct data to the gauge. Once the power supply to the gauge was resolved, it started working brilliantly. I’ll show this working in a follow up video.
