197 75° Thermostat in a Clio 172/182

[Krarl]

Has anyone or does anyone run the lower temp thermostat in their 172 for track use?

Any info regarding this would be ace

TIA

Yes. Not much to say about it though. You can buy direct from Renault or Puremototsport sell them.

Ta. Yeah RPD currentlynhave them cheap

Never bothered as they've always held fine for me bar FCS at Donny when it was 32 degrees. Not much of an issue at Knockhill.

Yeah I was weighing it up

It's more oil I'm worried about, just wondered if anyone sees any benefit in using the 197 one

I don't see the point of a lower temperature thermostat in the cooling system.

It's designed to get up to temperature and then stay within the recommended operating window. Fitting a low temp thermostat just means it opens earlier and the coolant gets cooled earlier, which means it takes longer to get up to operating temperature. Once it's running, I highly doubt a 'normal' thermostat would be closing again, unless you happen to live in Siberia in winter, lol, so a low temp stat would make no difference apart from increasing warm up time and the opportunity for engine wear??

 

[Krarl]

Just depends really. Oil takes longer to get to temp so that's where the majority of your wear comes from anyway.

Suppose once you change one variable then the other changes too

Yes, we run it Marts turbo 182 mainly to keep temps cooler for longer. No need for n/a. I got the gates one from autodoc for about £9

hmmmm, I might have a 75°c thermostat in mine. When I check the temps with a ODB dongle the temp rarely goes above 77-80.
The previous owner must have changed it for a low temp one as I have not changed it since I got it.
I guess I might want to change it out for a normal one? Car is only used on weekend drives and the occasional Nurburgring trip...
I hope it didn't damage the car.

perhaps it's stuck open?

Yeah might be, Ill be replacing it anyway. Any good known brands? RPD is £30

 

[GrahamS]

Gates is good. It’s a very simple device so should be cheap!

i've just got a euros special in mine. Opens at the correct temp (on my 197)
