Radiators & Parts for GMC Jimmy

GMC Jimmy Radiators Parts

The GMC Jimmy represents a long line of SUV trucks marketed by GMC starting in 1970. Although the final year of manufacture was in 2001, many GMC Jimmy models are still on the road. It is important for owners to know about how to identify, diagnose, and replace important parts and systems as these vehicles age, including the engine’s cooling system.

Although there are many parts included in the motor’s cooling system, here are a few important components that are more commonly repaired or replaced than others on aging Jimmy vehicles:

• Radiator: This is one of the most important components of the Jimmy’s cooling system. It is constructed of tubes and aluminum strips that help remove heat from coolant that circulates through the component.
• Water pump: Powered by a drive belt, the Jimmy’s water pump forces coolant to circulate throughout the motor. Water pumps fail over time because their gasket seals may break down, causing a heavy loss of coolant through pressurized leaks. Full replacement is usually the best option when this occurs.
• Hoses: Specialized hoses carry coolant to key places to regulate temperature.
• Thermostat and fan blade: The thermostat measures core temperature and activates the Jimmy’s fan blade when the motor’s temperature threshold is exceeded. Failure of a thermostat will affect fan blade operation, causing the temperature to rise above normal levels.

Factors such as corrosion, cracks, and worn gaskets may eventually cause parts of the cooling system to require repair or replacement with approved GMC Jimmy parts. The following are general signs of a problem:

• Coolant leaks: Drops of green fluid that accumulate underneath a Jimmy’s motor can mean a leak from one of several places. If left unaddressed, the drops will eventually turn into puddles and even lead catastrophic damage at a later time.
• High engine temperature readings: If your engine temperature readings are in “the red”, it could mean coolant leakage, insufficient coolant levels, and/or component failure.
• Defective hoses: Although cracked coolant hoses may not indicate system failure, they will eventually lead to leaks as the cracks become larger. The synthetic rubber material can dry and crack over time. Periodic hose inspections are important on older GMC Jimmy vehicles.
• Coolant odor while driving: Major leaks will cause fluid to spill onto a hot engine, burn, and cause a persistent odor in your vehicle once normal engine operating temperature is reached and/or exceeded. The odor will occur as you accelerate, cruise, or brake.

They should be labelled as genuine GMC OEM parts and specifically mention the compatibility for your Jimmy’s year of manufacture. For example, if you require brakes, searching using the year, make, and vehicle type may bring up a variety of brake equipment from different manufacturers. Brakes are available in front and rear sets.
