Radiator.com FAQ

Q: What other functions do Radiators provide?

A: Most vehicles with an automatic transmission have lines for the TOC (otherwise known as Transmission Oil Cooler), which cools the transmission. Some vehicles also have lines for the EOC (Engine Oil Cooler), which cools the engine oil.

Q: I was shopping on Radiator.com and noticed a few abbreviations. What do they mean?

A: TOC: Transmission Oil Cooler, EOC: Engine Oil Cooler, M/T: Manual Transmission, A/T: Automatic Transmission, PZEV: Partial Zero Emissions Vehicle, add more

Q: I was asked for the core dimensions of my radiator. How do I measure it?

A: Most radiators have plastic tanks and an aluminum core. When asked to measure the core, ONLY measure the aluminum part of the radiator. Measure length (side to side), width (top to bottom) and thickness (front to back). These dimensions are commonly displayed as “34 x 17 x 2.” Once you have these dimensions, it will be simple to determine which radiator you need.

Q: When should I flush my radiator?

A: Every vehicle has different specifications regarding how often the radiator should be flushed. Flush intervals should be listed in the owner’s manual, please adhere to those specifications.

Q: I smell a sweet, syrup-like smell when I drive my car. What does this mean?!

A: This most likely means you have a coolant leak. Coolant contains ethylene glycol, which gives off a sweet, maple-like scent. This leak can be caused by something as simple as a leaky radiator hose, but if you smell coolant in your cabin, it could easily be your heater core. The heater core is a small radiator located in your dash which generates your heat. It is HIGHLY recommended you get your cooling system checked if you smell this.

Q: How does running my A/C affect engine cooling?

A: When your A/C is turned on, it draws a load from the engine. It takes a significant amount of power to operate your A/C compressor, therefore it is harder to cool the engine. Fun fact: A/C also causes a significant loss in fuel mileage due to the power it draws.

Q: How do I check my coolant level and know if I need to refill it?

A: For the majority of cooling systems, the radiator cap (on top of the reservoir) can be removed to check coolant levels and add more coolant. If the coolant level in the reservoir tank is below the fill line, then ADD coolant. It is imperative to make sure that your cooling system is operating with a full level of a coolant.
