1985 Isuzu I-MARK Engine Cooling Parts

The engine coolant temperature sender, not to be confused with the engine coolant temperature sensor, is located anywhere within the engine cooling system and contains a thermistor that changes in resistance value as the thermistors ambient temperature changes. The engine coolant temperature sender is fed 12 volts and is typically used in conjunction with a gauge in the instrument cluster to provide a visual representation of the engine coolant temperature condition.

Product Features:

• Tin plated lead frame prevents corrosion and ensures a reliable terminal connection under adverse ambient conditions.
• Lead frame terminal size and location determined using image dimension measuring system or 3D laser scanner.
• Thermally conductive grease within the housing providing the most accurate temperature transfer from the engine to the thermistor.
• Plated brass or aluminum housings to prevent housing corrosion, ensures effective heat distribution to thermal element, and ensure a secure and leak-free thread mount.
• Computer-Aided Design (CAD), laser scanning and 3D printing – utilizing Fused Deposition Modeling (FDM) and Stereolithography (SLA) – in the connector terminal design process ensures speed-to-market and a precise connector fit guaranteed.

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.

The main device in any electrical circuit is a switch. In an electrical circuit a device is required to turn a component on or off when commanded by the operator, within the switch are contacts that will complete the electrical path to the load, or driven device. The operation of a switch may be manual from a person or could be electrical from some sort of controller or computer.

Product Features:

• Product constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.
• 100% thermo-shock and vibration tested to ensure superior performance in extreme conditions.
• 100% end-of-line tested to ensure accurate signal output providing product reliability, every time.
• Tin plated lead frame prevents corrosion and ensures a reliable terminal connection under adverse ambient conditions.
• Lead frame terminal size and location determined using image dimension measuring system or 3D laser scanner.
• Where applicable electrical connectors meet or exceed OE wire gauge, insulation, and terminal material requirements.
