FAQs
What is the main purpose of this adaptor kit?
This adaptor kit allows you to easily fit a coolant temperature probe directly into your vehicle's coolant hose, enabling better monitoring and control of engine temperature via a thermal switch or electric water pump controller.
What hose sizes does this adaptor fit?
It is designed to fit coolant hoses with an outer diameter between 32mm and 40mm.
Do I need to buy a separate temperature probe?
Yes, this is an adaptor kit. You will need to purchase the compatible temperature probe and control unit (like the Davies Craig 0444 Thermal Switch) separately.
Is this kit suitable for all vehicles?
It is suitable for vehicles that have coolant hoses within the 32mm to 40mm diameter range and require a temperature probe installation in the coolant line.
How difficult is the installation?
Installation is generally straightforward and involves cutting a section of the coolant hose and inserting the adaptor. Basic mechanical skills and tools are recommended.
What does the 'Picture For Illustration Purposes Only' disclaimer mean?
This means the image provided may not be an exact representation of the product you will receive. It serves to give a general idea of the product's function or type.
Troubleshooting
Temperature probe not fitting securely
Ensure you are using the correct size hose. If the probe is loose, consider using a sealant designed for automotive coolant systems or checking if an O-ring is missing.
Coolant leaks around the adaptor
Verify that the hose clamps are tightened appropriately on both sides of the adaptor. Ensure the hose is properly seated onto the adaptor's barbs.
Inaccurate temperature readings
Confirm the probe is fully inserted and making good contact. Check the wiring of the probe and its connection to the control unit. Ensure the adaptor is fully immersed in the coolant flow.
