Super 8

I had to replace the clutch fan in my 2001 6.0 a few years back with heating issues, problem solved.

My daily driver, 92, purchased it in 93 with 10,000 miles, now has 199,000

Allison was not used in the 8.1 Suburbans.

Did you change the cabin air filter?

You either have to put resisters on each bulb you just changed out or add one of these. https://www.amazon.com/Novita-LM487-Flasher/dp/B001KS6GIG

New cap and rotor?

BDubb, is this your color?

Odd, using the flashers in the driveway, everything worked good but using blinkers I have hyper flash issues. I ordered a new LED flasher relay, going to try that next vs adding resisters.

I just put these in my 2001 HD, front and rear. Remember to color code as needed. I needed 4 orange, 4 clear and 2 red, clear are for Reverse and DRL. I did find these all cheaper on Ebay. https://www.amazon.com/AUXITO-Signal-Yellow-Blinker-Parking/dp/B07V67DZLV/ref=pd_ybh_a_5?_encoding=UTF8&psc=1&refRID=Q66C8HM547CM64XEG6Z9 I used these in the outside front blinkers. https://www.amazon.com/AUXITO-Bright-Chipsets-Replacement-License/dp/B077W9J1KV/ref=pd_bxgy_2/139-8931403-8666616?_encoding=UTF8&pd_rd_i=B077W9J1KV&pd_rd_r=f499243b-87dd-4626-8f41-1ca558420ea4&pd_rd_w=C5pgd&pd_rd_wg=jyPQs&pf_rd_p=ce6c479b-ef53-49a6-845b-bbbf35c28dd3&pf_rd_r=J47VVWJW06ZXQB9A58FY&psc=1&refRID=J47VVWJW06ZXQB9A58FY

This will show you the difference between the tire sizes; https://www.tacomaworld.com/tirecalc?tires=225-75r16-235-80r16

265 vs 245 tires, brings your gear ratio 410 down to 373.

Remove the plastic cover above the radiator, clean out the debris/bugs etc between the radiator and condenser. Should help cool it down.

In the reman department, the BBB has been very good. https://www.rockauto.com/en/moreinfo.php?pk=7044032&cc=1303063&jsn=2416&_nck=Ekt6BqBF1pwlXdx0gYlm1esw98pF26vehMm%2FGG3C%2Fl2QOXSJubi7Wbtv3UuYQU5UpCsieVxbLU%2BzXhH01FTOH8gOMwUjkWsNg%2Ff7mQUCwrljQyQJr39KkcKr7GVauu8Rg1ZDYpCdXwePhW3x4WNjjot5%2FsbYoLvG%2BR5jiiSVdqOvSSPLh9Yz8dfhzP2Zi7f6KTbcmQfCYlel2VZWPH%2B6c%2F5w%2BG8UjI0HkNn7wtVRuX7KqYrIH3NEbjtfFwPcMH1WUWrrSSeMTlkJD6zpC35a7rWddS8rTvcq77KgM3m93lF6RoNFEwrIgOngz%2FWzrqyBgEvbNjstRhwHSbVEkff%2Fv50xKo1JukXqNk%2BV1IilkAkU1YMZwY1XGspgp%2B3ngTVMuvbpqqvVZs6QRSs72ef6Un8Zos2IAftfm8LgQN9sL%2BQ%3D
