What is the normal operating temperature for a 1997 Oldsmobile LSS with 3.8?

Answer 1

Depending on the environment, how long it has been running, and how is has been ran (city, highway...). If you were to let your LSS idle for about 10-15 minutes, is should be at normal running temp (which is usually between 140-170 Degrees). Dont worry if your temp is slightly higher (worry if you gett past 220 normal running temp). Once you start driving, the engine should cool down or stay around the same temp. If you're driving city, and there's a lot of stop and go, you will notice that the temp will raise. Don't worry. Highway driving will usually cause a lower temp (cooler air basicly blasting around the engine).\ I own a 1996 Oldsmobile LSS with a 3.8L also. But mine is a fine-tuned GranPrix 3.8. There shouldn't be much of a running temp between the two. Let me know if you have any more questions. -James
