Hello Everyone, I thank you very much for your input. It is a comfort feeling when some members indicate that their LS 400 temperature gauge is at the second mark from the cold. The temperature range in the manual was making me very nervous. Thanks again everyone.

Hello Everyone, I just purchased a used 98 LS400 which has 31K miles and a clean record. The temperature gauge points to around 2/5 of the whole range and I thought that it is normal since I have driven many other cars beside Lexus; other cars seem to have temperature point around 1/2 of the range. The seller did not indicates to to me there was a problem with a car. By a chance, I read a owner manual and found out that the temperature should below 1/5 of the range. With caution, I open the radiator cap of the resevior and I only see very small amount of pressure as a result. I thought to myself if the engine is running as hot as the temp gauge has indicated, I should see a lot of pressure build up. I want to check the temperature sensor but I do not know the spec and I do not know how many of them on this car. Have any one has an experience with this problem? I like to think that the previous owner made an honest mistake of reading the temperature gauge like I do, but with uncertainty and assuming I will have to pay a heavy price to fix the problem, I am beginning to think that I have been crossed. <_<
