Do you guys generally use a 180 degree farenheit for summer and 195 for winter?

 

I do, that is what I call them, but that is not the official term, they are designed for different regions/climates.

 

Personally I use the 195 year round

Actually, the Jaguar thermostats are more commonly listed as 82ºC and 88ºC (180ºF and 190ºF) but, anyhow, I always use the higher temp all year round, FWIW

I've never thought of different t'stats for summer or winter. Some cars are an easy change. some not so much. and, in these "green" times, spillage and drainage are a PITA!!


I've lived and worked in the hottest of climes and the coldest. with different critters as well. All cooled in summer and had enough coolant temperature to warm the cabin.


My LT1 is designed to run hot. Some opine that lowering the operating temperature increases power. Choice 160 F or 190 F. I run the 190 F. Engine cools right on the hottest of days. Plenty of warm for the coolish days. High 30 F's at worst.


What it would do in the - 0 in our stormy NE, not known and I don't want to find out!

Yes, my LT1 fans are setup with all stock stuff.. but they come at the "Stock settings the LT1's primary fan will come on at 228*, and the secondary fan comes on at 235*." GM did this of course for better emission readings... no reason to change to a lower temp thermostat with good radiator and fans. I think will all the cars GM made, they have a clue on how to do this properly.

Sealing all the incoming off so it goes into the radiator/AC condenser with side plates and dense foam on the other areas resolved any lingering
air flow problems. The Jag grille allows enough air that cooling is not a issue. I have though about adding a deflector on the bottom but do not
not want more stuff below the car.

I adjusted my Jag temp gauge (with a resistor in line) to read the new temps are in the Normal range ... lower temp shows at N-o and higher r-m. Never goes higher than that even stuck in heavy traffic with the AC on. It has seen 111F in heavy traffic with the AC on!

With air moving into the radiator at freeway speeds that temp reading will drop to just before the N...

 

wait! does he have a Corvette engine in his car or the original Jaguar 4.2 engine?

I am not talking about LT1 engines with twin fans, I was referring to the original XJ-6.

 

Jose:


No matter. Please the engine design. All will work just fine. Jaguar, Lt1, LS1, Stove bolt Chevy six. flat head ford V8, etc.


Relation to ambient???


But, to each his own.

I have the original 4.2 straight 6

 

Follow Doug's use of 195 degree year around and all will be well.
