Hello,

I’m preparing to fix my slow leak on the coolant valley on my 2008 LC200 w/ 3UR-FE. I’m working in a community shop space, so I want to be sure that I have all the parts (and more) that typically wear out ready to replace.

I am roughly following this video ( ) and a few other threads on mud as a guide. But want to be very sure I have everything to ensure this goes smoothly (im sure I can store my cruiser at the club but id rather avoid it if I have to).

I have the various one time use gaskets and washers and other components purchased to repair the leak. I also have replacement EGR valves, water pump, idler, etc to do at the same time.

My question is - what else should I have on hand during this repair? I’m thinking that I should just do a full coolant hose replacement too since these can crack and I really dont want to stall the repair. Any ideas what the part numbers are for those? Should I have anything else?


Thank you!
 
This thread has a bunch of info and part numbers. Not sure what else you are looking for.

 
I would do hoses and radiator in addition to what you have listed especially if you still running the original equipment from 2008
 
It isn’t clear if it’s OE from 2008. Is there any easy way to tell?
