South African roads test our vehicles daily, from Joburg dust to Cape Townβs salty air. Despite harsh conditions, many car owners believe engine cleaning is only cosmeticβor even unnecessary. This myth can cause hidden damage, breakdowns, or costly repairs. Letβs bust the top misconceptions and show why South African drivers should prioritise regular engine cleaning and cooling system care.
Myth 1: βYou Never Need to Clean Your Engineβ
Harsh realities like dust, gravel, leaks, and debris pile up under the hood. Neglect lets corrosion develop, risks fire hazards, or damages sensitive parts. A clean engine shields performance, helps spot small leaks before they become big problems, and even preserves resale value.
Myth 2: βA Dirty Engine Doesnβt Affect Performanceβ
Dirt acts as insulation, trapping heat. This strains your carβs cooling systemβan issue in busy city traffic or up Gautengβs hills. Grime can hide leaks, making problems escalate quickly, while contaminants can enter your oil.
Engine oil inspection for contaminants can check how cleanliness affects engine health.
Advice from the Motor Industry Workshop Association recommends annual cooling system checks to maintain optimal temperature (miwa.org.za).
Myth 3: βA Quick Hose Down Is Enoughβ
Hosing the engine bay can be risky. Modern cars have electronics and sensors prone to water damage. DIY methods force water where it shouldnβt go, risking costly faults. Instead, trust pros equipped with the right materials, coverings, and techniques (wheels24.co.za).
If you notice smoke after washing, schedule a smoke from engine or exhaust inspection.
Myth 4: βRadiator Flushes and Coolant Arenβt Neededβ
Your cooling system depends on clean coolant. Over time, coolant loses effectiveness, allowing rust and overheating. Regular radiator flushes keep the system efficient and protect against overheating (cars.co.za).
Book a radiator flush or cooling system flush for thorough care. Chronic overheating? Consider radiator replacement or comprehensive engine overhaul.
Myth 5: βEngine Cleaning Is Just Cosmeticβ
A clean engine helps mechanics spot leaks, failing parts, or early warning signs. Excess grime drives up heat and can cause issues like a check engine light, misfiring, or noisy operation. Persistent overheating? Book a thermostat replacement.
