Low temperature thermostat

Would it be worthwhile to just get a used one from the sale section and new seals?

Problem with buying used units is you do not know their condition until it is too late. Buy new and get all four seals (o-rings of two different sizes).

In Arizona it’s difficult enough to keep it at 180 let alone 160.

We have seen 175 F on a fully instrumented 2001 S running in 100+ F heat.

Was that in Phoenix driving thru city streets driving in traffic? My 2001 S and my son's S couldn't stay at that temp with new water pumps, thermostats, fluid and clean radiators. Maybe coasting down hill.

I have the low temp thermostat on my 986 and thinking about getting it on my 987.2 base (9A1 but with port injection) - from the product notes LN says it might trigger a pending or active CEL:

I'll probably get one when it is time to do the WP.

On my 986 (2000 S) that was heavily tracked, the low temp thermostat let me start a session with a lower "base" of temperature, which prolonged my session time before things got too hot.

I won't do it justice but you guys should read the guides and information on low temp thermostats and the cooling system for bore scoring from Hartech who are a UK based specialist.

I added low temp thermostat when I replaced the water pump and engine mount. Also added S center radiator and a 996 front bumper. Noticed cooler/more stable temps. Added the 996 bumper not 993 as previously stated at same time as S radiator so cant say which change made more difference. Also plan on adding a GT3 style top bumper vent for added look.

Oh, this is interesting. Is the 993 front bumper a direct plug and play? If so, would you have pictures of your vehicle that can be shared on the forum? I didn't know or think this was possible. Did the temperatures end up being cooler based on the bumper change? Or was this a direct result of the centre radiator?

Inquiring minds want to know

OK. Makes sense. Thank you both.

[bcrdukes]

Oh, that's interesting. Is it a direct fit?

[WillH]

That looks like a 996 bumper to me.

I think you are right, sir!

bcrdukes,
Yes Direct Fit I did mine too

[mikesz]

Yes 996 bumper I corrected my original post. Direct bolt on. I removed the moustache and replaced opening with mesh to keep leaves out.

Fascinating convo. Seems to make a case for the LTT stat. Question: will a 160deg stat throw a CEL due to coolant temp variation from OEM?

Absolutely not.

Thanks so much JFP. Say, do you think an S oil cooler on 2.7 motor would add significant cooling?
