Hi, so my Clio is running cool, and has been for a few years now so time to sort it. My guess is the thermostat, so have got a new one and intend to replace it tomorrow. Not done this before and I class myself as 'very basic' when it comes to mechanical things i.e. Can do basic stuff. Haynes manual (if I've read it correctly, dangerous I know!) suggest to take off the distributor cap for better access...I've not started looking/mauling about yet. I assume replacing the thermostat is easy (I've done it before on cars in the past...in my twenties when rolling around on the driveway at a weekend was the only way to fix something). Before I start...anything I should watch out for? Thanks (and apologies for sounding like a complete incompetent ****).
