Transmission cooler lines are responsible for carrying transmission fluid to the radiator for cooling. Leaks in these lines can occur due to wear, damage, o r loose connections.

Common Causes of Cooler Line Leaks:

Cracked o r Damaged Lines: Over time, transmission cooler lines can crack due to corrosion, heat, o r wear. Physical damage to the lines e.g., from road debris o r accidents can also cause leaks.
Loose o r Damaged Fittings: If the fittings that connect the cooler lines to the radiator o r transmission become loose o r damaged, fluid can leak from the connections.
Old o r Worn Lines: Older vehicles like the Suzuki Cultus may have brittle o r worn-out cooler lines that are prone to developing leaks.
Rust o r Corrosion: Cooler lines are often exposed to road salt, moisture, and extreme temperatures. Over time, rust and corrosion can weaken the lines, leading to leaks.
How to Fix:

Inspect Cooler Lines for Damage: Check the cooler lines for visible cracks, damage, o r signs of rust.
Tighten Fittings: If the connections are loose, tighten them to stop the fluid leak. Be sure not to overtighten as this may cause further damage.
Replace Damaged Lines: If the cooler lines are cracked o r corroded, they should be replaced with new, high-quality transmission cooler lines.
What to Do:
Inspect the cooler lines for cracks o r damage, and tighten o r replace the fittings if necessary. If the lines are rusted o r damaged, they should be replaced to prevent further leakage.
