cooling system tech

A little while ago, we quickly alluded to the difference between mechanical and electrical coolant temperature gauges in a post about troubleshooting a radiator. But this topic deserves a little […]

It’s the middle of summer here at OnAllCylinders world headquarters. Or as we like to call it, “peak overheating season.” It’s a time where folks often have an eagle-eye trained […]

Did your engine temperature start unexpectedly pegging the needle? Do underhood temps creep up while you’re idling? Or do they spike at highway speeds? Obviously, these symptoms all point to […]

Q: Why do I need to use antifreeze? … A: The fluid you use in your engine’s cooling system can affect its performance. For most vehicles, a 50/50 mixture of antifreeze and […]

In a liquid cooled engine, the thermostat is a valve installed between the water pump and the radiator. It controls when the radiator starts to cool the engine. It’s job is to […]

Q: Can I remove the fan shroud on my cooling fan? … A: It might seem like it’s just in the way, but the fan shroud plays an important role in the […]

Q: What is a double-pass radiator? … A: In a single-pass radiator, coolant only crosses the radiator core one time. Fluid enters the inlet. It flows across the core in […]

By Nicholas Thomas, Mishimoto Back in the infancy of liquid-cooled engines, nearly all emissions systems would vent chemicals and harmful vapors into the atmosphere. No PCV or CCV lines, and […]

Cooling Basics – Row Quantity vs. Tube Size In the radiator core, coolant flows through tubes. The tubes are joined together by the fins. More heat can be exchanged when […]

The fan clutch is an important part of your cooling system. Its drive shaft attaches to the water pump. Then, the fan attaches to the clutch housing. The fan clutch’s job is […]
