My fan/s cut in at 94 (when it's running right) measuring from top hose outlet, takes it down to around 84-85, but unless the stat is working properly, even if the fans kick in, there won't be enough coolant flowing through it for the fans to do anything.
I used Holts 2 part rad flush & as Ady says make sure it's thoroughly flushed out, that means bleeding it up to & beyond stat opening temp to make sure everythngi gets flushed several times. I did mine with the stat out so everything was open.
right that makes sense, without removing the stat and using a saucepan is there an easy way to test the stat is opening correctly? I don't really want to start messing around with an already temperamental coolant system and add a problem where there wasn't one to start with
It might be a safer bet for me to put it into a bongo garage and have them drain, flush and refill the system and whilst it's there get a pukka Mazda stat fitted too?
If the rad fan/s kicked in at 94, did they bring the temp down? - may have risen by a degree or two first with lag, once the fans kick in, increase the revs, this will force more coolant through the rad therefore cooling it quicker if the stat is working, if it carries on rising, then chances are the stat ain't working proper (of course it could mean you've got a blocked rad). Don't know what you'd do with the saucepan though
Only way to really test the stat is to take it out TBH.
You can't polish a turd - but you can roll it in glitter.
