Title: Switch out radiator?
Post by: PSUAztek717 on May 15, 2017, 04:23:27 PM
Would it be worth it and would one be able to switch out the standard radiator with the "heavy duty" radiator (acdelco part 21635)  to tow the full 3500 lbs?  More or less can it be converted without any additional modifications to make the HD radiator fit where the standard radiator was as if it were a like for like part?

When i got my tek i thought it could tow 3500 lbs, but when i read the manual its 2000 without the tow package.  I already put on the hitch, but what else is included with the dealer installed tow package?

I wouldn't bother with it, but my total package is 2000 lbs +/- 100 lbs and i dont have any passengers.  Plus the engine has 77k original miles and i got a killer deal on the tek, so i have no problem shell out the money to have it done.  Cheaper and more entertaining to drive than a pick-up.   :D

I would do that and add on a tranny cooler. Also, do a ChrisFix super flush for the coolant system.

I put my Monroe Airshocks on (so easy to come off...no rust whatsoever and torques to 63 lbs) and did a superflush.  (The old radiator coolant smelled like power bait.)  Towed the Pontoon 30 min to my parents house this morning with no overheating issues and it was smooth sailing...like I did not even have a trailer in tow! 

Tranny cooler will go on in the winter most likely.  I may have someone put it on for me...I don't really trust that guy's youtube video.  Doesn't really show you where to cut the lines.  Plus, It looks like most kits are plug and play so there should be no need to cut the lines.  I'm also going to do new rotors and brakes.

Where did you get your CAI?  And how did you do the light bar on your tek?  And if you have any luck finding a place that sells brush guards for our teks let me know!
