As posted on here probably thousands of times over the years, I have the slow warm up time on my GTI in the winter months. Last year, and the year before, I changed the thermostat and a temp sensor. Guess what?, it didn't work.
This year, it's still annoying me so I'm wondering if a quick DIY fix may help for a few months, then I can remove it. I'm thinking of doing what they do in ice road truckers, and putting something in front of the radiator, maybe just partially covering it.
The car is slow to warm up in anything under about 12 deg and it isnt likely to be above that for a while up here in Inverness, so what do you think? Is this a bad idea, very bad, or maybe worth a try?
