Ok this weekend I am going by the Toyota stealership to pick up some more Toyota Red coolant the guy i bought it from put the green glycol in it. He also made some custom fitting on the lower hose to the radiator which is leaking enough to cause air and bubbles etc. He didnt use thread dope or seal up the fitting. I can weld it but i have to drain everything, weld and dope the threads then flush and put in the Red coolant. A friend of mine thinks the radiator cap (new one but not an oem one) is causing the problem because the plastic where it hooks up is grinded away and gnawned. I disagree i think its sealing up there just fine.

If someone could take a couple of quick good pictures of a front shot of the rad cap area with the cap on and off from top and sides, front to back that would be awesome!

It wont kill it but yes i would change it over to the Toyota Red. Don't buy their pre-mix either just but the full then blend it with your own distilled water. Here is a link to my how to take care of your lexus is300 chan.
