Your engine doesn't usually fail all at once - it overheats quietly until it's too late.

In Part 1 of our 3 - part Cooling System Series, we break down why cooling system neglect is the #1 cause of catastrophic engine failure, and why so many vehicles are sent to the scrapyard long before their time.

We cover:

1) Why coolant doesn't last forever( and what happens when it's ignored)

2) The most common cooling system failures mechanics see every day

3) How over hearing causes warped heads, blown head gaskets, and cracked blocks

4) Warning signs drivers miss until the damage is already done

5) Why "just topping it up" is dangerous

This episode lays the foundation - what the cooling system really does, how it fails, and why maintenance matters more than people think.
