Author	Subject: Is my thermostat the issue?
cornish_pug Regular Location: Marazion Registered: 18 Dec 2009 Posts: 368 Status: Offline	Post #1 Over the last couple weeks I've noticed my coolant temperature gets high at high speeds or when traveling up hill (when the engine is working hard). I've read that this could be due to a thermostat not opening fully. My coolant level is not critically low but could do with a top up. What are your thoughts? ________________________________________ Team Diesel

Fan did come on last night when the temperature just nudged 100°C ________________________________________ Team Diesel
