So, I was washing my RX today and popped the hood to wipe the water out of the engine bay. I noticed red calcium build up on the top corner of my radiator on the passenger side. Could my radiator be leaking? Any ideas? Help?

Since it is a CPO I think I should probably make an appointment with my local dealer and have them check it out. However, have any of you guys experienced anything like this?

 

That is the color of the Lexus/Toyota coolant/anti-freeze. Since it must be coming from some place you more than likely have a leak some place. Would take pictures if possible for your personal record(s) and look for any stone damage. Then, get the RX over to the dealer soonest. Not something you want to push especially if it is still under warranty.

 

check the reserve amount see if its down alot, at least if there is still lots there you know its a slow leak,

other than that, next time you go for a drive, pop the hood and check it out.

 

Take it in it is a CPO. There was a TSB for the radiator but the potential leak was in the bottom, they extended the warranty on the radiator to cover for this failure.

 

Thanks guys, I will be making an appointment with my local dealership today. Will keep you guys posted.

 

Well got off the phone wit my local service rep. he said i will need a new a radiator and will get a loaner for the day or so......

 

There you go!

 

The RX is at the dealer and I have my loaner IS250. It should be done by tomorrow. I love my Lexus Dealer!

 

Awesome. I only wish my dealer still had IS loaner cars

 

Get that IS screeching!

 

Oh i plan onto...any idea how to burn out in those with auto tranny? Wish they had the six speed manuals instead then I would have had some real fun

 

Is your car done? How did you make out?

 

Well I got a call from my service rep and they told me they ordered the wrong radiator so i get to keep the loaner another day

 

They probably took your radiator to that corner shop and had it welded...so it took time...jk!

How's the IS?

 

Probably hey as long as it works...lol...I am loving the IS my wifey misses the RX. I was actually looking around pricing used IS CPO's if I could pull the trigger I would on an IS350 but man these cars are still out of my reach even used. However, atleast I know that Lexus is holding thier values.
