Otherwise it's fairly straight forward, AFAIR. I didn't do my own since I was under warranty. I can't imagine that a shop charges more than a hour to do it. If you have not had the antifreeze flushed, have it all done at one. The thermostat itself is probably $6 at an independent store and $20 at the dealer. > How about if I just make the heater work better on very cold days by >blocking off the flow of cold air to the radiator with a piece of >aluminum foil? It will probably work, but it's definitely a hack. If you stop in traffic, the car will probably overheat a bit. I'd fix it the right way. Bob
