I have an un-modded 1.8 VVC 165 K series which i which is barely registering any water temperature on the gauge when driving normally in these cooler/cold months. It does when left to tick over for a long time eventually hit over 80. I have recently had silicone hoses fitted so airlocks are probably not the issue, it did this before and still does it after. I do get some heat out of my heater but pretty much only when i stop and the car heats up. I thought that this was just normal cold weather behaviour until I discussed this at a meet last night so I am now after some ideas to fix. Is it the thermostat? if so which one do I buy 74, 82, 88? or do i just do the QED mod if that is the right route again which temp? Or is it something else? Any advice appreciated thanks Allan
