Just changed the coolant in your car, and it overheated after only a few days, even leaking like a sieve? Don’t rush to blame the coolant! Today, we’ll uncover the real culprit behind this!
1. Coolant Quality? Check the “ID Card” First!
Yes, coolant quality is paramount! But be wary of cheap, generic brands—they may contain inferior chemicals that decompose into acidic substances at high temperatures, accumulating over time and clogging the radiator and corroding metal. Even the best engine can’t withstand such treatment!
The Right Solution from FAW
▶ Look for the original factory “ID Card”: FAW J7-specific long-life coolant, using carboxylate black technology, preventing high-temperature deposition and improving heat transfer efficiency by 15%.
▶ Dual protection against freezing and boiling: -35℃ antifreeze + 130℃ anti-boiling, all-season protection, specially formulated to cure all kinds of “cooling problems”.
2. Vehicle Hazard: Scale is the Real Culprit
Cooler cries foul: “The blame is too big!”—Scale buildup in the system is the real culprit! Long-term neglected scale acts like a “blanket” around the engine, drastically reducing cooling efficiency; even the best cooler can’t save it.
Jiefang’s Correct Solution
▶ Regular “Cleansing”: Thoroughly clean the cooling system every 2 years or 200,000 kilometers.
▶ Avoid Mixing: Mixing different types of coolant will cause them to “clash,” doubling corrosion! Jiefang’s original coolant features adaptive coverage technology, providing long-lasting corrosion resistance and is suitable for all vehicles.
3. The Truth About Leaks
Leaks aren’t really the coolant’s fault! The truth is: the ethylene glycol in the coolant dissolves old rust and scale, exposing hidden pinholes and cracks.
Jiefang’s Correct Solution
▶ “Check-up” Before Changing Coolant: Always check the pipes and radiator before changing the coolant; repair any pinholes immediately.
▶ Acid-Base Balance Technique: Test the coolant pH with pH test paper (normal range 7.5-11). If it’s below 7.0, replace it immediately! Jiefang original fluid has a stable pH value, ensuring corrosion resistance.
