Nobimmer 694 Report post Posted October 13, 2009 What is the water temp on a F/L m20b25 meant to be when "warm" ie middle of the gauge. I have just finished redoing the plumbing and because I'm not using a E30 cluster, I don't have a gauge. Took it for a drive and it felt bloody hot. It could be because there is no interior and windscreen though. And any idea how I can measure it with a basic probe style thermometer that my dad uses for refrigeration?

Normal operating temp around 88 deg mark & obviously - make sure it's bled properly Quote Share this post Link to post Share on other sites
Nobimmer 694 Report post Posted October 13, 2009 Yeah- I have just about finished sorting the gauges. All are after market so am having trouble finding a decent set for a decent price. Quote Share this post Link to post Share on other sites
