Ok, so I know that the expansion tanks lose coolant over time, but I believe mine is leaking around the top (not the cap). I don't have a pic (sorry) but basically, due to heat and age, the top of the tank appears to be separating a bit. Is there an inexpensive option for replacing the entire assembly for a 2001? I'm afraid to buy another used one.
My other thought was to use some kind of epoxy or glue to seal all around the top of the tank. Has anyone tried this, or does anyone know a good product that will withstand the heat and vibration?
It seems to have lost about 1" since I last checked maybe a month ago. I noticed fresh red coolant on the tank.
Thanks

I had thought that this tank is integral with the fan shroud? Because I broke the fin off inside due to something falling inside and needing room to extract it, and had to then fish out all the broken pieces. I had considered replacing, but opted against once it was a larger piece. I dunno if repair is recommended. Maybe just bite the bullet and replace, or, if you're not really losing much coolant (one tank per year), then leave alone...my .02

Yeah, I might have to bite the bullet and just order another one. It'll be around $175 with shipping, so not as bad as I had imagined. Maybe I'll try an epoxy just for kicks, since it's not pressurized and I have nothing to lose. Thanks for the part number...it's embarrassing but for some reason I have trouble figuring out the part numbers for this car sometimes.
My weekends are always crazy, so does anyone know how involved this will be, so I can plan? Do I need to drain the radiator and remove the hoses, etc. or can it be slipped out?

It can be slipped out.It has 6 bolts.Take the bottom panel off and the air cleaner filter box out.You can drain the rad and remove the top hose to ease removal.If you order from the forum vendor you will get 10% off.

I used the Toyota seal packing compound to seal a small coolant leak at the rear cross-over joint from the outside without taking off the manifold. Pretty strong stuff and saved my several hours of work.
