Design & Looks
In a recent YouTube stunt, a crew dumped a 2‑liter bottle of Pepsi into a car’s radiator instead of normal coolant. The bright caramel color immediately stood out against the metal, making the experiment look more like a prank than a serious test. The video’s host even filmed the bottle being poured, showing the fizz bubbling through the engine bay.

Can You Replace Engine Coolant With Pepsi? What Happens When You Try

Performance & Mileage
Within minutes the temperature gauge spiked. Pepsi lacks the anti‑freeze agents and corrosion inhibitors that conventional coolant provides, so the engine overheated quickly and brown sludge formed in the hoses. The car’s mileage dropped to zero as the driver shut the engine down to avoid permanent damage. The lesson was clear: sugary soda can’t transfer heat the way engineered coolant does.
Price & Rivals
Regular coolant costs roughly $15‑$20 for a five‑gallon jug, while a two‑liter bottle of Pepsi is under $2. The cheap price tag tempts DIY thrill‑seekers, but the potential repair bill for a ruined radiator or water pump can easily run into hundreds of dollars. In short, the cheap alternative ends up far more expensive.
| Engine | Mileage | Price | Top Features |
|---|---|---|---|
| Standard 4‑cyl | N/A (experiment) | Coolant $15 vs Pepsi $2 | Heat transfer, corrosion protection, freeze resistance |
FAQ
- Can I use soda as a coolant? No, soda lacks the chemicals needed to protect the engine and will cause overheating.
- What happens if the coolant is replaced with Pepsi? The engine overheats, sludge forms, and serious damage can occur.
- Is it cheaper to use soda instead of coolant? While soda is cheaper upfront, the repair costs far outweigh any savings.
