I had to put every 1 week like 500 ml of coolant

i did a check up on my ISF - 100,006 Mile

probably i have to change my water pump as i read here which most have problem with it and also the radiator fan motor needs to be changed

THE GUY told me something about " engine cover leak ~ center plate leak or engine block water ~ i really didnt got it that much or am not that good with the engines ~!!! is there anyone have any idea about it ? or i guess maybe its because of the water pump caused this ???


they are pro In Lexus this Garage ,,

he told me its a plate under the engine , we can fill with silicon if it can be !!

am kind of worried since he told me its under the engine ~ is this situation normal for doing this ?

Your leak is most likely in the valley between the intakes on the head. Some of the other members with higher mileage have experienced this same issue.

I'd check and make sure it's not the water pump first.

But the other thing you are talking about is the coolant valley under the intake manifold

Check out this thread: https://www.clublexus.com/forums/is-...-slightly.html

It talks about the whole thing. It is unfortunately more common than anyone would like.
