Overflow & Washer Bottles

Plastic bottles under the bonnet live a hard life. Years of heat cycles, vibration and corrugations can leave an overflow or washer bottle cracked, leaking or brittle. A replacement is an inexpensive fix that avoids bigger problems.

Coolant overflow bottles

The overflow bottle holds coolant as the engine heats and cools. A cracked bottle can let coolant escape, so it is worth replacing at the first sign of a leak or a stained, cloudy tank. For more engine cooling parts, see radiators and the full cooling range.

Washer bottles

A leaking washer bottle means an empty reservoir just when you need a clear windscreen, which matters on dusty outback roads. Most replacements come ready to take the original pump, though some include a pump. Check the product page.

Brands

Panel House supplies almost all of this range, with factory-style bottles for many popular models. Canna Fabrication offers a couple of alternatives.

Getting the right one

• Add your vehicle with the vehicle finder to see only bottles listed for it.
• Check whether the bottle includes a cap, pump or sensor.
• Compare the shape and mounting points with your original.
