Bolec WL601P Push-On Water Level Probe
The Bolec WL601P is a push-fit water level probe designed for use with Bolec water level alarm modules such as the WL601 and WL701.
It detects low coolant levels in radiator systems, helping prevent engine damage due to overheating.
Key Features
- Push-in style with M4 stainless steel nut for clamping action
- Installs into a standard 9.5 mm (3/8″) hole—no thread required
- Rubber compression seal ensures a tight, leak-proof fit
- Includes a 6.4 mm spade terminal for quick electrical connection
- Compatible with Bolec WL601 and WL701 water level alarms
- Suitable for plastic tanks (requires two probes for ground path)
Applications
- Low radiator coolant level detection for vehicles, tractors, and marine engines
- Water level monitoring in plastic overflow or preserve tanks
- Auxiliary water detection for long-range or off-road applications
Note: When used in non-metallic tanks, a second WL601P probe must be installed and connected to ground to complete the sensing circuit.
