Interesting issue this winter.

For the last two years I was tooling around in my 1.8 75 with a variety of water leaks. I've finally got all of them sorted (water pump, elbow outlet, HG, and inlet manifold, so pretty much the full set) and everything was going well until the recent cold snap.

The car takes a lot longer to warm up now, and rather alarmingly is now very good at cooling back down again - on one long downhill stretch (about 4 minutes off the throttle at about 30mph average) the temperature drops below 1/4.

From having "classic" cars I know one cheap bodge for overheating is to either swap the thermostat or remove it entirely so that more of the coolant flows through the radiator. This feels the same as that, but I wasn't sure whether it was possible on the K series. I've got a timing belt and water pump due in the spring when I'll get it looked at, but is it going to be a big problem for the next month or two?
