Came home today after 100+ degree temps to find a bunch of coolant on the ground, leaking heavily from the radiator area. It looks like the leak is coming from the top - not from the weak nozzle that commonly breaks, but "appears" to be coming from the metal spine to the right of the main upper hose (or lower part of the picture below). That is where the fluid seems to be fresh and moving/fluid. Anybody know where the source of the leak could exactly be?

I'm assuming I need a new radiator, correct? Looking to see if anybody else has had a similar issue and source of leak. Wondering if I can limp it to the mechanic once the weather cools down or if it needs a tow - could be a dumb question, i know.

Also - What have you guys paid for a new radiator installed? Thank much in advance!

 

Looks like it could be a bad seal. What makes you think the whole radiator needs to be replaced?

 

That'd be music to my ears, as I don't anticipate keeping the car much longer. The radiator is well known issue among ISF and LS460's which is why I defaulted to that assumption. Where would you presume the faulty seal is? Doesn't appear the be a hose. Thx.

 

Are you sure that's not the nipple that we all seem to break at some point? Cuz, it sure looks like it to me. If you DO have to replace the rad (which I'm almost certain), it's an easy and cheap fix. I got my rad for under a hundred bucks (lifetime warranty), and replaced it in about 90 minutes. Throw in another 20 bucks for coolant and your golden.

 

Thx Chris - strangely enough, it doesn't appear to be leaking from the nozzle. Clearly, there was a slow leak happening there but that's not where the majority of the coolant appears to be coming out. Regardless, I'm bringing it in today for a replacement. Only a few hundred bucks installed so not worth the risk of driving it in this heat.
