Thermostat type? 160/180/195f?

[Danish-Syclone#0748]

I need help figuring out which to choose.

I live in Denmark, Europe so the climate is a little different over here. Never really hot over here.
But I never run the truck in winter time

The truck is standard engine wise, but small changes made to injection and cooling system.
I dont run strip, but I dont say no to a show off when a wise guy in his BMW thinks he cant beat me

Which would you choose?

Thank you for any help you give, Allan

I went with the 160. Engine runs cooler and you will still have all the heat you want.

Thx for fast reply Hammer head

The problem with the 160 is thats its close to the point where the injection runs warm-up or richer in
fuel mixture. Or so I have heard

Then get a 180

Get a 160*, keeps the underhood temps wwaaaaaayyyyy down.

Never had any problems with issues about it getting it into closed-loop.

I agree 160* is best choice, keeps the temps down which may also help with knock.
I tried the 140 and it was a bad idea. Made the engine run rich amongst other weired things. . .

I've heard the 140* causes all sorts of issues.

Sounds about right. The computer is going to command the truck to dump fuel untill it warms up. If it doesn't know running temp is now at 140 it's gonna keep sucking that gas.

The higher temp ones are just for emmisions.

160 is best.

I believe for less wear on the engine & better mileage, a 180 would do better than a 160 T-stat.:2cents:

Just a question where do you actually get a 140* STAT. I have never seen one. Just saying.

Back when I ran one it was a different PN, but that's the one they show now.

I ran a 160 for years in the summer and winter and never had an issue.

Run a 160 in the summer and 180 the rest of the year.

Re: Thermostat type? 160/180/195f?

Is there really much of a benefit from the 180 and 160 as far as knock goes? ---

Re: Thermostat type? 160/180/195f?

That is what i thought but never used one. It is a MARINE PART. Because i never seen a car with one and or one in a part store listed for CARS !!! Just saying. If an engine runs to cold it can sludge up and cause issues Thanks.

You asked a question and I answered it. I'm not endorsing the use of the d*mn thing. I personally feel that it's poor decision to run one on a SyTy unless special needs arise.

I use a 180* and have never ha d an issue with too warm or too cold.

My thermostat is the OE 195 degree thermostat that was installed by the factory in 1991. . I examined the thermostat 2 years ago when the engine was rebuilt but it appeared brand new so I reused it.

Results:
The engine temperature is determined by the ambient temperature..My vehicle's cooling system is in excellent condition and the OE 195 degree thermostat still permits the engine to run fro,m 160 to 200 degrees when the ambient temperature is below 90 degrees. The engine temperature soars to 195 - 210 degrees in stop and go traffic when the Texas heat is above 90 degrees. The thermostatic fan clutch is a new GM unit (2 years old) but the OE fan clutch was still good. A good fan clutch is essential for a cooler running engine in stop and go traffic.

I'm in the UK and I suspect your ambient temps are lower than ours. My Ty had a 160 on it when I bought it. It seemed to take quite a long time to warm up. This could have been made feel worse by the truck having other issues at the time as well, I dont know. I changed to a 180 Robertshaw HP stat and it seemed to warm up faster and goes closed loop sooner. If you have a mostly stock truck and dont have any knock issues, I would run a 180. You can always go back. I had the some issue years ago on a 87 Vette and it seemed to run better with a 180. I'm sure a 160 would be OK, but I dont think a street vehicle should run too cool, you can have more issues with crankcase condensation on vehicles that only do short journeys especially in colder climates.

After the rebuild, my engine has 9.7:1 compression ratio. I use 93 octane Chevron gasoline exclusively. The summer formulation of Chevron 93 octane gasoline may be the reason there is no engine knock and timing retard when the engine is running at 200 degrees F. If I put any lower octane gasoline in the engine, I believe engine knock would become loud and clear.

My engine has only one knock sensor in the back of the block below the distributor and is not as sensitive to engine knock and lifter noise. That also may be a factor in detecting knock and timing retard. .

If your climate is all the time cold just install
the 180 deg unit we have very hot climate here
in South America so the first thing we do is remove
the thermostat period it works great all year round !!
