Hi guys, this is my first thread. i'm in need of help, My 00 Tundra (v8, 4x4, 120k miles) It keeps on overheating after barely driving down the road. I've searched for an answer but I haven't really found much, most sites say check the thermostat and the radiator cap, so I replaced both but there's no change. Checked my hoses and they're fine there's no clogging. Besides that I have not noticed any leaking under the truck. but after it overheats somehow coolant is boiling on the front side of the radiator. perhaps there's a crack? I'd hate to replace the radiator but it's summer time in AZ and the temp can get brutal.
if anyone has any ideas or suggestions on what I can do, any advice is appreciated! this is my daily driver to and from college and work so i need to get it running good again!!
thx!!

 

Check your entire cooling system and flush it.

Yes. And make sure the anti-freeze is mixed to a proper ratio with DISTILLED WATER. Anti-freeze lowers the freezing point and INCREASES the boiling point of water.
