The water temperature gauge is a key instrument on the dashboard that informs the operator of the engine coolant temperature. If the temperature gauge doesn't move at all, goes to maximum immediately after start-up, or shows unstable, "jumping" values, these are classic symptoms of its failure. A malfunctioning gauge makes it impossible to monitor the engine temperature, creating a risk of overheating and serious, costly damage, such as a blown head gasket.

A new gauge allows you to monitor the temperature in real-time, giving you full control and the ability to react early to any abnormalities.
A functional gauge is the cheapest insurance for your engine. It protects a unit worth thousands from overheating and seizure.
The gauge is fully adapted to work with the original JCB temperature sender and electrical system.
Before starting any work on the instrument panel, for your own safety, always disconnect the negative (-) terminal from the battery.
Incorrect gauge readings are often caused by a faulty sender in the engine or a chafed signal wire. Diagnose these components before replacing the gauge.
When disassembling the dashboard, work gently to avoid damaging plastic clips and other gauges.
After installing the new gauge, turn on the lights to ensure the illumination bulb is working correctly.
Answer: It is possible, but a more likely cause is a faulty temperature sender in the engine giving an incorrect signal, or a short in the signal wire.
Question: The needle on my gauge doesn't move at all. What is the cause?Answer: The most common causes are a faulty temperature sender, a broken wire, a blown fuse, or the gauge itself is faulty. Diagnosis should start with checking the fuse and wiring.
Question: How do I tell a P21 cabin from the older P12?Answer: The P21 cabin (produced from approx. 2002) has a more modern, rounded design and a different dashboard layout compared to the older, more angular P12 cabin. This gauge is exclusively for the newer P21 type.
