I've been running a 170 auto T-stat for 15 years. Still have the 145 in a box somewhere.

Hello Hagman,
Can you please post a photo of your t-stat housing ?
There are some pictures on the EFI thread I started.
Sounds like you are on the right track. I really dig that you are in France and playing with a Supra, with a big block no less, very cool. I have friends in Denmark that have a bunch of American V8 race cars that I go help them with, they are an oddity for sure. With your fuel prices I know you have to be dedicated!!
The thermostat does not control water to the exhaust, that is flowing all the time to keep the manifolds cool. So chose your t-stat to control minimum engine operating temperature. I would use 160+ for sure. No shortage of cool water to keep the engine from overheating and a warmer engine is a happier one, to a limit obviously.
Cheers!
Thank you for your comment Kevin, it conforts me on the t-stat and exhaust.
And yes, when we talk about our engine size, people look at us with big eyes and think we are crazy to drive this boat, because of the gasoline price here ...
when you love you don't count the cost ;)
Cheers
Hi guys.
I'm back home after 1 week in south of France and 1 week in Toscane Italy.
Next week will be the week of fixing the heat problem and the go back to the water.
I will also start builing the tower led spots.
Finally, Skidim sent me an email. They have now a new item #50313 to replace our old housing to fit a car t-stat.
I have first to do more test to be sure my t-stat is guilty before placing an order ...
Here is the link to the housing : http://www.skidim.com/prodinfo.asp?number=BBB252980
Thanks for the info, that's good to know. It's cheaper than the solution that was available a couple of years ago.
Double check measurements and connections if you're considering replacing the tstat housing. I replaced mine with the older style that skidim previously offered that uses the automotive tstats. Only after installing it did I notice that the locations for the manifold and water pump hoses were swapped front/rear from the original locations. Not a real big deal since I was redoing all the hoses anyway, but it really cut down on the clearance between the alternator belt and pump hose on the port side & required some creative bracketing to keep things from rubbing.
Hopefully you just need a new tstat, but thought I'd mention it just in case...

Thanks Mike for advises.
I tested yesterday the t-stat in the kitchen. It opens at the good temperature. Means I need to check now the circulation pump and rust presence in the block coolant system. Unfortunatly here in France weather has never been so awful for this month. I can't start the engine with rain outside, so, I have to wait !
Hi guys,
Finally, my engine is no more overeating. The bath of cola, white vinegar and lemon juice saved the t-stat. Now it sits at 150°.
Now I have to wait for sun and it goes back to water.
I also have all stuff to build my led tower spots. It will be cheap and chic. About 8$ each including Led ...
Keep watching :)
