Sticky thermostat
Hi
Since I’ve has my 75 diesel, my thermostat has always been stuck partially open. So, it doesn’t get to temp fully. What’s the best solution to this? New thermostat? Some sort of mod? Is it a straightforward job? And, where am I best getting the relevant parts from? Thanks. Ravinder

If you do the in-line mod, ensure you buy a Renault 5, 88-89C stat made by Gates, FirstLine or Wahler. These are known to optimise the running temperature. Other brands may not, due to valve leakage.

Thanks. So what’s the difference between just replacing the thermostat with a standard 75 one and this in line one that people talk about ?

12 hours, half the engine and the possibility the replacement thermostat will also become stuck. In my experience.

in future the in line stat is 10 mins to change.... you cut the pipe, put the stat in, do up the jubilee clips and top up the coolant... the engine will run 9 degrees hotter than OEM which makes it slightly more efficient without doing any harm.... IMHO the only reason to do the OEM stat is if you are replacing the pump at the same time or if the old stat has failed shut...

There have been one or two reports in recent times that suggest the current/latest/third generation OEM thermostats suffer from the same issue as the most common one (2nd generation). The problem stems from a physical or chemical change in the wax, which causes them to start opening early. They don't stick open or become 'sticky', they simply bleed coolant through the valve at lower and lower temperature until the engine never warms up.

I’ve got one of those in my stores, have mine running at 92° super, prefer this type to any other type. At 92° the engine is far more efficient and also less thermal transfer as it keeps it stable between 90/92 degrees
