⚙️ Key Features

• One-way sender for double instruments
• 40-120°C range
• 0.045 kg
• 72 published applications across six engine series

🔌 Function

Changes resistance with coolant temperature so the instrument shows the engine's running temperature.

⚠️ Common Signs of Failure

• Gauge reading permanently cold, permanently hot or wandering
• Gauge needle jumping with engine vibration
• Coolant weeping around the sender thread
• Terminal corroded or the connection loose
• Reading disagrees with a hand-held check on the same engine

🛠️ Service Notes

• Confirm whether the installation uses a one-way sender for double instruments before ordering, since senders of the same size can differ in the number of terminals
• Sender 840345 is the alternative for the 827151 sender and the 833927 thermoswitch control, so establish which arrangement the engine carries
• Seal the thread and top up coolant after fitting, then compare the gauge against a separate reading
