Automotive Thermostat Install

[Kinchyle]

I'm trying to figure out the 70 Celcius (158F) replacement for the thermostat. I've sent out an email to 3-4 automotive aftermarket websites. The thermostat says it's made in Germany and it looks like the same type of thermostat in the German cars. Volvo and Porche have a close model I just need to find the dimensions that match. Volvo and Porche also have 4 cyclinder cars which should match up to our flow requirments of the 3 cylcinder seadoo.
Another reason why I think the stock thermostat and the Riva thermostat is european is because the ratings for those thermostats are 70C which is 158F. American thermostats are 160F rated.

Of course the thermostats are European. The engines are made in Austria.

Instead of emailing all kinds of people go down to a pep boys or similar shop and take a stroll through their dozens upon dozens of thermostats. If you are stuck on getting OEM then find an aftermarket thermo then find what applications it was made for and whala you have your OEM thermo. You are making this too difficult.

I took it to NAPA auto parts. They found the dimensions but couldn't find a 70C.
Looks like the volvo, porche ,bmw(European) make a 4cylinder 70C just have to find the same dimensions. The only thermostat that I have found that posts dimensions is Stant but they don't have a 70C or 160F.
I'm trying to find a 70C(158F) automotive thermostat that will fit the RXP/RXT.

Anybody see any engravings on the Riva 70C before they installed it or take a picture of it?

the Riva only says 54 mm and USA, not even a temp marking.

Why when dave let me borrow the cut tool. I just have to cut out the thermostat and add a 70C(158F) degree,same as Riva's. Then epoxy it together. It's just plastic tabs that hold it together stock, so epoxy will be overkill.

total price 30 bucks.
Riva or RR total price 180~
see my reason


....just have to find the 70C to fit.... should be soon

hmmmm. The ones with 54mm kinda look like it.
GLM13040 looks just like it but it's not made....
(54mm, 160° Thermostat fits Mercruiser 4 cyl. engines with closed cooling & Aluminum exhaust manifold

I see some 140F would they be better than the 160 ?

Interesting article, sounds like they are talking about Riva's thermostat. I think it's a mercruiser

Getting closer......
I'll send emails out tommorow to verify dimensions.
Looks to be made by Sierra for Mercruiser.
I think GTXX put me on the money.
