Has anyone installed a 160 thermostat on the LS7 and do any of our supporting vendors sell them.

I would like to know as well!!!

I bought mine from HPE

Oh no!!!!!!.........not again.......do a search in this forum.

Yes and yes. Your operating temp runs about 15* higher, air circulation permitting. You will find alot of information here in the search.

Yes, they are available through Halltech. I use the 160* thermostat, Halltech Stage 1 Filter/Tune and American Racing Headers. The motor runs cooler, down around 175-180* during normal cruising speeds.

My question was 160 thermostat on LS7 specifically and not the LS1, LS2, or LS6 to which you will find many post, but not on LS7 and that was my question AFTER doing a search.

Thanks Buchanan, that's the kind of information I was looking for.

What is hte effect of running this cooler thermostat in colder climates? I plan to drive my C6Z in the Chicago land area most all days this winter when there is no snow on the ground.

Isn't there an issue with oil temperature and the burning off of acids, water, and other extraneous by products of combustion and internal friction?

The Clevite Kid

The lube oil naturally runs somewhat hotter than the coolant, primarily because the oil coming out of the connecting rod bearings is thrown against the bottoms of the pistons to cool them. The small change in coolant temperature will not affect the oil temperature enough to make a difference.

But you are correct - the oil has to be kept warm enough to keep the water vapor in the blowby from collecting in the crankcase.

He meant this section. Check out the FAQ.

Sorry MAJ Z06, but I found the FAQ to be of no help on this question since none of the 51 post in the FAQ deals with my question. Also the search in this forum is to vague. Thanks to buchanan I have an answer that is specific to my question.

I had one installed at LG Motorsports last week. (lgmotorsports.com)
So far no problem. They also intalled LG longtube headers, halltec air filter, the exhaust switch and dynotuned it.

How close to 500 rwhp did you get.

Glad I could help. In addition, the motor temps. due increase when consistanly running hard at the higher RPM's. It's not uncommon to see it approach or slightly exceed 200* but generally, it's considerable lower than stock. For those concerned with cooking out the moisture or ??? You must not be driving it hard enough!

It's All-Good!

That has not been my experience. My oil would normally be at 167 degrees before, and would rarely get above 185 after sitting at idle, or doing stop-n-go traffic for an extended amount of time.

I can't remember what my exact coolant temperatures were before, but now my car runs at about 180 degrees while cruising, and 195 while doing stop-n-go. My oil temperature is about the same, although it can get up into the 170's on warm days, and gets as low as 157 on cooler nights. The hottest it ever got was when I was at the track a couple of weekends ago. After about 10 laps, my coolant was at 220 degrees, and the oil was at 230.
