glang Posted July 8, 2019 Share Posted July 8, 2019 Cant seem to reply to the previous post with the same title but wondered if the thermostat is opening fully as this could explain the apparent discrepancy between engine and hose temperatures Quote Link to comment Share on other sites More sharing options...
nang Posted July 9, 2019 Share Posted July 9, 2019 Best take it out and suspend it in hot water and see what it does. Tony. Quote Link to comment Share on other sites More sharing options...
TReslaV8 Posted July 10, 2019 Share Posted July 10, 2019 Many thanks will try the thermostat test. What temp should it open? (sorry to be an ignoramus, but just checking!) Thanks David Quote Link to comment Share on other sites More sharing options...
RobPearce Posted July 10, 2019 Share Posted July 10, 2019 Typical thermostats for our cars are 82C or 88C. I'm not sure whether the V8 is different but they're not exactly precision devices. If it opens properly in not-quite-boiling-at-ambient-pressure water then it's working. Quote Link to comment Share on other sites More sharing options...
TReslaV8 Posted July 10, 2019 Share Posted July 10, 2019 Cheers, much appreciated. Quote Link to comment Share on other sites More sharing options...
glang Posted July 10, 2019 Author Share Posted July 10, 2019 let us know what you find as it'll be unusual if the first thing suggested is the actual problem Quote Link to comment Share on other sites More sharing options...
