    Engine quits

    May 10: After a four hour drive to our cabin our 2013 Tahoe engine shut off while ten miles back on a dirt road. All dash lights, head lights, etc were still working. But when I tried to restart I got nothing, not even a click. So I got out the portable jump starter battery pack, hooked it to...

    Well. She was almost perfect.

    Sorry to hear this. I had a guy run a stop sign in front of me and I T-Boned him at 50mph. I had my foot on the brake so hard that it took all of the shock when we collided. I thought it was broken but it turned out my foot was just very bruised and swollen. Any way I always say that if you...

    Adding an oil cooler

    The plan is to install a Tru-cool trans cooler and dorman 620-654 7/9 cooling fan assembly. This will include trans fluid and coolant change. BTW when I started the Tahoe to drive home a 1:00am this morning the trans temp was already at 106°. The vehicle had been setting in covered parking...

    Radiator Fan Questions

    I counted the blades, seven on the driver side, 5 on the passenger side.

    Adding an oil cooler

    I am sure that there is no external trans cooler. Also nothing going to the driver side of the radiator so no oil cooling either. No the temps don't drop if I back off to 45MPH. The coolant temp rises as well. This is going up two 6 degree hills and one 7 degree hill. I left the trailer at my...

    Radiator Fan Questions

    Does the 7/9 700 watts make a big difference? I am experiencing high coolant & trans temps while towing with the stock 5/7. Have a new external transmission cooler to install. Thinks of doing the fan upgrade at the same time.

    Adding an oil cooler

    This has been an interesting thread. Interesting in that I have been having the same experience with high temps and it's got me totally freaked out. Going up to our home in the mountains pulling a 20 foot enclosed trailer with one motorcycle my transmission fluid reached 235° on several...

    Sluggish accelerating at 30-50mph

    MY 2013 XLT does the same thing. I chalk up to being under powered.

    2013 new owner towing report

    I don't have a stock one. I have zero. Which line leaves the radiator to return tot he trans (our cooler in this instance) The bottom line from the radiator would make sense.

    Now which line is which top to bottom?

    This is what makes sense. Use the radiator as a pre-cooler. It would seem that if I routed to the radiator last, the radiator would reheat the trans fluid to what ever the water temp was (over 210). Thanks

    The fluid goes thru the radiator before or after the cooler?

    2013 new owner towing report

    Thanks, should I bypass the radiator when installing the TruCool or run them in tandem?

    2013 new owner towing report

    I run a little over 200 in the Phx heat. An I-17 trip from McDowell North to Peoria and I'm 215 with the 20ft trailer loaded with one Harley Trike. Back South empty is around 207. Never had a trans temp gage so I had no idea what it should be.

    I'll check the gearing again tomorrow, but the 2 speed TC was a big reason for my purchase.

    2013 new owner towing report

    New Tahoe Owner with a few questions/concerns

    Nice looking 2013 you have! We bought an LTZ a few months ago. The passenger side window does end the down cycle with a thump! The others less so. Our windshield washer fluid line came loose in the back so I just put it back together and it's been good since. The inside driver door handle is...
