Automotive Plastics: radiator repair, radiator tanks, radiator repair

Question
Dear Octavio,
I have a 97 Chevy PU truck Silverado V-8 1500. There is a bad crack in the passenger side plastic tank. Is it possible to replace the plastic tank myself? If so where can I purchase one?
Thank you,  
Mike

Answer
Dear Mike, Radiator tanks for trucks are not available in the market. you can only get these for passenger cars in places like http://www.plastank.com/.Should you get your tank anywhere, you would need specialized tooling to take off and replace the tank. I urge you to look for the whole radiator in junk yards. Sometimes you can fix a tank without the need to dismantle but this is a rare exception. I will need clear pictures of the crack to see if installing what we call a positive grommet seal is feasible and safe. Thanks
