im tired of my 2000 ls v8 saying its overheating....any suggestions? I see that this is a common problem with the Ls but geeezzzzzz. AC doesnt even blow cold.
Take the panel off that goes over the headlights.
Look and see if your rad isn't plugged up with road crap etc.
If it is then use a waterhose to clean it out.
Same thing on my 01 LS V8. Replaced the reserve tank, bled the system and all was well.Or low coolant level. If he has a cracked resevoir, he could be low on coolant. Happened to me.
