GruvenParts Billet Heater Core Coolant Tees (07-14 Sierra 3500 HD)Find parts that fit my vehicle

Description. STOP USING CHEAP PLASTIC TEES !!! THEY BREAK AND LEAVE YOU STRANDED !!

As many have already found out the hard way, the cheap GM plastic coolant tee fittings for the heater core are prone to breaking at the worst possible times. Don't risk ruining your expensive motor due to a simple plastic coolant fitting failure ! Once the plastic tee breaks (and it WILL break, just search the forums), you have about 1 minute to pull over, stop the motor, and start walking. If you happen to be towing, up a steep grade, you probably wont be able to save the motor from becoming an expensive paper weight. Your coolant system is only as strong as its weakest link, and this plastic heater core tee has definitely proven itself to be the weakest link !

GruvenParts billet heater core tees solve this problem entirely. These fully barbed precision CNC machined from solid 6061-T651 aircraft grade aluminum and TIG welded by our licensed A&P mechanics in our high tech Atlanta machining center. We then pressure check each fitting to ensure the integrity of the weld. Each tee includes 2 short pieces of HPS high performance silicone hoses as well as 4 high quality stainless steel worm screw clamps. The billet tee is installed using the supplied silicone hoses and clamps and fits over the existing factory hard line connections with no modifications needed. You could probably drive the truck over this fitting and not hurt it, but we suggest you do that with the plastic tee and install ours!
