Carquest Premium – Radiator (Part No.811311)

Radiator

from

$289.99
Carquest Premium Radiators offer one of the largest product ranges in the aftermarket, covering more than 95% of the popular automotive and light truck applications. Carquest Premium Radiators meet or exceed original equipment specifications, ensuring that products fit and perform just as well or better than the original parts, providing you peace of mind.

Product Features:
  • Our B-type tubes feature central reinforcement to provide greater tolerance to pressure. Stronger tube design means drastically reduced probability of tube failure.
  • Our deep extrusion header provides a stronger tube to header joint which is more resistant to the effects of vibration and thermal tube expansion, virtually eliminating tube to header leaks.
  • Our fin edges are folded for increased stability and heat disbursement properties.
  • Our included “multi-fit” attachments allow one radiator to cover multiple vehicle applications without sacrificing OE fit. This results in wider vehicle coverage with substantially less inventory.
  • Thermal expansion cuts allow for longer life and reduce failure rates by allowing improved core expansion and contraction during normal heat cycles.
  • We design and manufacture all our radiators to meet or even exceed Original Equipment specifications. We take pride in producing the most reliable replacement parts in the market.
  • We use longer header tabs for increased pressure resistance. This reduces the potential for tank to header leaks.

Carquest Premium – Air Conditioner Refrigerant Pressure Sensor (Part No.ABA1074)

Air Conditioner Refrigerant Pressure Sensor

from

$135.99
The Carquest Premium line of vehicle electronics are designed for OE form, fit and function for both import and domestic vehicles.

Product Features:
  • Designed and manufactured with high quality materials, industry leading electronic components and strict quality controls. Engineered to exceed OE performance and to meet the uncompromising demands of service professionals.
  • Direct fit replacement matches proper OE fit, form, and function and ensures trouble free installation of your A/C Pressure Sensor.
  • All units are helium leak tested on fully automated mass spectrometer equipment before end-of-line testing.
  • All units are tested using automated end-of-line testing equipment that pressurizes the A/C Pressure Sensor and checks full-spectrum functionality and electrical output to ensure each A/C Pressure Sensor meets manufacturing specifications before packaging
