Exactly what was needed, November 23, 2018 By Erik (REDFORD, MI)(Verified)
They send you everything you need to change your thermostats. And the video instructions are a big help. Only thing I would add is, after you bleed the coolant system, start your truck and keep adding coolant until the resivoir is full. Merchant hit it out of the park as usual
Solved my warmup problem., January 9, 2018 By Daniel (SALINAS, CA)(Verified)
Product worked well, how to video answered any questions. Now the truck warms up quickly and doesnâ€™t throw an under temp code.
LLY T-stats, December 13, 2017 By BOB (Holland, MI)(Verified)
Not only were the parts correct, they fixed my temp issue completely. Also, a major thanks for Eric’s simple but thorough video covering T-stat diagnosis and replacement. The job went exactly as he described. Added bonus points for the info on the bleeder bolt for refilling the coolant. I never would have guessed that’s what it was!
OEM Quality Parts!, December 11, 2017 By Gustavo (Millican, TX)(Verified)
Once again, MA has provided me with OEM quality parts at a fraction of the OEM price! I really appreciate the "kits" that MA provides so I won't inadvertently forget to order a gasket or seal needed to complete the repair. As a former dealership parts manager, I like the idea of "kits". I used to put together kits for common repairs in the shop and the technicians (and parts countermen) liked the ease of getting "all" the parts need for a repair. Keep up the good work MA! I will definitely be a returning customer, as I have no intention of letting go of my 2009 LMM (currently has 147K miles). We all know that "all things mechanical can fail" so I hope it's not too often but I know I'll need you again!
Cooling System Service., October 16, 2017 By Daniel (SALINAS, CA)(Verified)
Replaced thermostats, hoses, coolant and installed coolant filter at 140K on my 06 LLY. Truck hadn’t been warming up properly for some time and started throwing a operating temperature time code. Verified easily with a temp gun on the tstat housing that it wasn’t sending unit or gauge(coolant would only reach 150-158 after a decent drive). Products were all very good except the lower radiator hose which was a C+ AC Delco aftermarket peice that just didn’t fit right, it works, but I would go with the dealer piece if I did it again.
LB7 Thermostaat replacement, August 2, 2017 By Mark (Lox, FL)(Verified)
This replacement kit included everything I needed to R & R the thermostats while I was replacing the injectors. the cooling system had to drain for the injector replacements so this is a good time to change out the thermos. They are factory OEM, it included the rubber o rings, the o ring for the oil filler tube and was a very simple job. make sure you put the thermostat with the two small holes at the rear of the thermostat housing with those 2 small holes toward the rear of the engine, then put the other thermostat in the front. I have to say M/A is a great company, Eric has put together and very well thought out Complete Injector replacement kit. It Has EVERYTHING. I loved the easy open packaging and every bag was labeled
