Just thought I'd share this.
was driving along the M'way the other day thinking how great the engine was running etc. running at circa 52-4 mph. external temp 13C, engine at a steady 87C. no sooner than I thought it was running a steady 87C it started to go up. only to 89C then back down to 83C and back to a steady 87C - I gave up watching after that but thought how great it was to be making such 'fine tuning' by itself and to relatively small tolerances   |

Sounds like you have replaced your original thermostat by the PEL500110. right?

Interesting, the original thermostat is supposed to only start opening as of 88°C and is fully open as of 96°C.
The PEL500110 is supposed to open as of 82°C and is fully open as of 88°C. That's why with the running temps quoted by you I thought you had made the change, same is I and many others here.

hmm.
I have seen it go up to 90's (possibly 96/97C in circumstances where you'd be more likely see higher temps ie straight into traffic after working the engine a bit, but not the other day (I've seen this several times before) when just cruising along, it was more like a bit of 'fine tuning' and like I say I'm pretty sure it's the original. |
