hengti 2 Posted April 1, 2006 I have done a search and have taken the general concensus to be that an 82deg stat will help an engine run cooler than the std 89deg stat however ... I'm still not sure how this can work. I'd have thought that it wouldn't affect the ultimate running temp (reached once either stat has fully opened), only the amount of time it takes the engine to reach that temp - ? can anyone who's fitted an 82 stat confirm that this is the case, or offer a technical explanation as to how it works if it does actually lower running temps thanks Share this post Link to post Share on other sites

My emerald ECU show's water temp to be around 70 ish degrees. Share this post Link to post Share on other sites
pug_ham 242 3 Cars Posted April 2, 2006 Yes it does, I fitted one to mine recently & it now sits on the lower side of the fourth bar on the temp gauge to what it did when an 89'c was fitted. Full thermostat kit (with seals) was £7ish from a local motor factors. Graham. Share this post Link to post Share on other sites
hengti 2 Posted April 2, 2006 82 fitted now running a little cooler - just below fourth bar, instead of just above it still keeps rising in traffic though ... happy enough all the same cheers for the assurance Share this post Link to post Share on other sites
Gavtrials 0 Posted April 2, 2006 that skip brown 72 degree stat sounds intresting but wouldn't this be a little cold for the engine or wont it make a difference? Allso what about the 82 degree stat, what car is that from? Share this post Link to post Share on other sites
Henry Yorke 269 3 Cars Posted April 2, 2006 I would agree with your first thoughts as once it is open then that would be it. To run cooler, you would need a diesel fan switch in the rad so the fans kick in earlier. If it has made a difference, perhaps your old themostat was on its way out. I put my old one in a pan of water and boiled it just to see how far it opened!! Share this post Link to post Share on other sites

What a lower temp stat may do is extetnd slightly the time it takes to "over" heat. They all run hot in traffic though and its normal for fans to cut in. I run a 72/75 degree thermostat in mine from SBC, not sure if it's "better" than and 82 or an 89 though but it seems to run ok. Share this post Link to post Share on other sites
