Increased Coolant Flow, Decreased Coolant Temperatures The rear cylinders on the 5.9/6.7L Cummins suffer from a lack of coolant flow, and therefore, experience the highest coolant temperatures. This can cause excessive pressure to build in the cooling system, especially the rear of the block and blow out freeze plugs externally, or the smaller diameter plugs under the valve cover, leading to a failure. Our coolant bypass kit adds a secondary thermostat, that unlike other brands, works based on temperature instead of excessive pressure. This solves the problem before pressure becomes an issue by ensuring consistent temperatures across all six cylinders. Benefits: Lowers coolant temperature at the rear cylinders Ensures consistent temperatures across all cylinders Prevents damaging coolant pressure build up Complete kit comes with braided hose and AN O-ring fittings to ensure a leak-free installation. Why do I need a Fleece Coolant Bypass? One of the biggest issues on the 5.9/6.7L Cummins is the coolant flow problem to the rear cylinders. This can cause catastrophic failure or blow outs of the freeze plugs in an over-temperature / over-pressure condition. The Fleece Coolant Bypass is one of the most important additions you make to improve the reliability and longevity of the Cummins platform.

No se pudo activar, pero fue culpa de servicio al cliente.
Compré la tarjeta porque muchas compañías no querían activar mi celular chino, un Xiaomi Note 12 Pro+ 5g, y cuando lo puse dentro de mi celular pude llamar perfectamente al servicio de activación donde me pusieron mil excusas sobre que mi celular chino no funcionaba y no iba a funcionar y me desactivaron mi tarjeta SIM de Amazon, fui físicamente a una sucursal y me atendieron mucho mejor y me activaron una SIM literalmente igual a ésta, y ahora estoy con internet perfectamente funcional con un plan prepago como la de esta tarjeta. Bien producto, terrible servicio al cliente.

Works as prepaid sims for T mobile
I had postpaid T mobile connection (part of family plan) and I wanted to shift to the prepaid one (T mobile connect 15$/mo) as it was cheaper for me. I called up T mobile customer care, they asked for the (1) family plan account #, and (2) the account pin (3) a new sim card (this one from amazon) I just had the account # and told them the name and cell no. of the family plan head, so they called him up and got authorization to drop me from the family plan. They then transferred me to their prepaid division, they asked me for the Sim # (not the cell phone no.) that is written on the back of the sim cards purchased from amazon. Then they just transferred/ported my old no. from postpaid (family-plan) to my individual pre-paid plan. After, the phone got disconnected with customer care (as the old sim now became defunct). I replaced my old sim with my new sim (but with old cell #). Even though they said that it will take 24-48 hours for my new sim to be activated, it got activated in 5 minutes and I received welcome texts from T-mobile. Could not be happier! It was no hassle at all. Additionally, T-mobile gave me 1 month of free usage in prepaid. It has been almost 1 month that I saving around 10$/mo with this prepaid connection, I have faced no issues.
