nobangmycar Posted July 1, 2014 Share Posted July 1, 2014 My Hilux runs a little colder than I would like on the gauge, so I took a look at the thermostat on Monday and it has a brand new aftermarket 82deg one in there. TT240-180. I never trust aftermarket thermostats in Toyotas, and I have had a bad run with aftermarket thermostats in the past in all sorts of applications. The genuine thermostat listed @ Toyota is apparently 82/95... does this refer to 2 temperatures? I worked @ Partmaster for years and understand part numbers, but never struck this in a thermostat. Some sort of dual stage thermo? Anyone else had this problem? Quote Link to comment Share on other sites More sharing options...
Styles Posted July 2, 2014 Share Posted July 2, 2014 The description in the catalogue says 82-95, so my guess is that it's an opening range, starting to open at 82 to fully open at 95. There's also a "cold area" spec one that's 88-100. Quote Link to comment Share on other sites More sharing options...
Spencer Posted July 2, 2014 Share Posted July 2, 2014 Yea it will be a range. Depending on the engine and state of the cooling system I am pretty keen on 80 degree thermostats in most old cars. Sure its doesn't help fuel economy, but its a massive difference under the hood from a 80 to 95/100 degree thermostat, might save a M series from a BHG up a hill haha. Should try a decent gauge at some point and see what temps it actually operates. Quote Link to comment Share on other sites More sharing options...
nobangmycar Posted July 8, 2014 Author Share Posted July 8, 2014 Cheers for your help fellas. I think I will just spend the not much dollars and get a genuine thermostat. Thanks for your help styles, I am constantly frustrated by not being in the parts game any more with access to all the catalogues!!! Quote Link to comment Share on other sites More sharing options...
