w140amg Posted March 4, 2009 Share Posted March 4, 2009 I was about to buy the Long Life Antifreeze/Coolant and saw the 50/50 Pre-diluted Super Long Life Antifreeze/Coolant. Which is better? Quote Link to comment Share on other sites More sharing options...
lenore Posted March 4, 2009 Share Posted March 4, 2009 Should be the same, except one you would have to mix your own distilled water...... Quote Link to comment Share on other sites More sharing options...
1990LS400 Posted March 4, 2009 Share Posted March 4, 2009 I'd recommend buying the premixed coolant at the Toyota dealer -- it's the same product sold and used by Lexus dealers. The premixed coolant saves the trouble of mixing with distilled water and ensures that the coolant complies with the vehicle requirements. For a fluid that is usually supposed to be replaced every 24 months or 30,000 miles, using "long life" coolant makes no sense. The only people I know who ever have radiator or other cooling system problems are the ones who try to stretch coolant change intervals ... sometimes to infinity. The repair shop I use charges so little to change the coolant with Toyota/Lexus premix coolant and can properly dispose of the old coolant that it isn't worth my while to do it myself and find a waste disposal facility that accepts coolant. A gallon of premix coolant used to top up our Toyota/Lexus cars lasts about a decade. Quote Link to comment Share on other sites More sharing options...
Threadcutter Posted March 4, 2009 Share Posted March 4, 2009 I was about to buy the Long Life Antifreeze/Coolant and saw the 50/50 Pre-diluted Super Long Life Antifreeze/Coolant.Which is better? I was told a long time ago to use nothing but "Toyota Red" (bought at the Toyota dealership). I was waved off the Super by the guys at the Toyota shop. I followed that rule and have never had any issues. Quote Link to comment Share on other sites More sharing options...
jcrome04 Posted March 5, 2009 Share Posted March 5, 2009 I want to change my coolant soon.. What kind exactly do I buy?? And how much of it?? Quote Link to comment Share on other sites More sharing options...
jcrome04 Posted March 7, 2009 Share Posted March 7, 2009 Ok guys... don't make me start a new thread now! :D On the 2nd gen LS is there just one drain valve? I can only see one on the bottom of the radiator. Quote Link to comment Share on other sites More sharing options...
jcrome04 Posted March 8, 2009 Share Posted March 8, 2009 Fair warning to all. Out of spite..... ( and some need for actual info ) I will start my own thread tomorrow! Hahaha. I want to be sure on how to clean the IACV and drain and fill the coolant in a 2nd gen LS. I've done a little research but want to be 100% sure before I tackle this. Oh.. and I WILL make a DIY for the IACV cleaning since there's not too much info on it! ;) Quote Link to comment Share on other sites More sharing options...

jcrome04 Posted March 8, 2009 Share Posted March 8, 2009 I actually have an LS. I'll try to get as much out of it as I can. Is the IACV similar? Quote Link to comment Share on other sites More sharing options...
