Supra Saltare in France

[Jetlink]

I can never seem to get my thermostat reading to get even close let alone greater than 150-160 degrees Fahrenheit when I run on the hose. I guess the easy fix here is a new thermostat and go from there.

I'd try the thermostat like the others suggested. Also, were all of the blades of the old water pump impeller intact when you replaced it? Could it be impeller parts or other debris in the hoses?

Simple test:

Take the thermostat out. And put it all back together. It won't hurt the engine at all. In fact, seeing as we only drive these in warm weather you really don't need one. All it's doing is helping the engine maintain a constant temperature.

But to test if it's the thermostat or not, remove it. Open the housing, pull out the t-stat, put the housing back together. Then hook up your garden hose and start it up. If it runs perfectly cool, you know it's the t-stat.

Mike, the old impeller was in good shape, only the blades took the form of the pump, but no debris inside.

Haugy, that's exactly what I was thinking to do. Then if it's still hot, the only other thing I see is rust in the coolant system of the engine block (I had this problem on my 5.0L TBi 1989 Camaro, rear cylinders were not cooled because of this).

I'm trying to clean and save the old T-stat (it's in coca cola + cillit bang), as I find the replacement part on the net, the s-stat reference is R026003, it costs 134$

Next news in two weeks, I'm going to hollydays with my GF in Italy.

Thanks to every one for your help

Yikes! That t-stat here in the US is about $6.

If you have another place to buy it, let me know

I don't know if it's the same thermostat as mine, but I know mine was the $60 dollar-ish variety. I could change out the housing and start using the cheaper one, but that's not cheap either.

Isn't this a 454? Mine just uses a regular auto thermostat. Gates 33006S is the 160F version. http://www.amazon.com/Gates-33006S-T.../dp/B000Q0WZJS

I think this is the same part number for the Ford engines, too.

Mine is a 454, and I assume his is too. If I remember correctly it depends on who did the marinization and what year they did that work. They used different thermostat housing at different times and unfortunately mine is one that requires a non-automotive style thermostat.

don't know why but the 454 thermostat in mine is very hard to find online. it used to be part #0701 from Skidim but it's not showing on their site. they don't show any thermostat for PCM 454. i'd shoot them an email.

this is what mine looks like
