Sierra Temperature Sender TS26611, 240 Degree F, 1/4-18 Thread, 10-32 Stud Terminal, Replaces 362AN-D 90402 B-936-1 52320S004

The Sierra TS26611 is a marine engine temperature sender designed to monitor coolant or cylinder head temperature and send an accurate signal to the temperature gauge on the helm. It carries a 240 degree F temperature rating and installs into a 1/4-18 threaded port, making it a direct fit for engines and blocks machined for that thread size. The sender terminates in a 10-32 stud connection for a secure, corrosion-resistant electrical connection to the gauge wiring harness.

Temperature senders like the TS26611 are a common wear item on inboard and sterndrive engines, and a failed or drifting sender is one of the most frequent causes of an inaccurate or non-functional temperature gauge. Because the sending unit threads directly into the engine block or cylinder head, matching the correct thread size (1/4-18) is essential for a proper seal and accurate reading. The TS26611 is cross-referenced to several OEM and aftermarket numbers, so it can be used as a direct replacement wherever those part numbers are specified.

Frequently Asked Questions

What is the Sierra TS26611? The TS26611 is a temperature sender that threads into a marine engine to monitor coolant or head temperature and send a signal to the temperature gauge, rated at 240 degrees F.

What thread size does the TS26611 use? It uses a 1/4-18 thread, so it fits engine ports machined for that thread size; other Sierra senders in the same family use different threads for different applications.

What temperature rating does this sender have? 240 degrees F is the rated temperature for the TS26611 sending unit.

What kind of electrical connection does the TS26611 have? A 10-32 stud terminal is used for the wire connection to the gauge, giving a secure threaded connection point rather than a spade terminal.

Does the TS26611 cross-reference to OEM part numbers? Yes, TS26611 replaces OEM/aftermarket numbers 362AN-D, 90402, B-936-1, and 52320S004.

How much does the TS26611 weigh? The sender weighs 0.09 pounds.

How is the TS26611 different from Sierra's 18-5896 sender? Both are 240 degree F temperature senders with a 10-32 stud terminal, but 18-5896 uses a 1/8-27 thread while the TS26611 uses a 1/4-18 thread, so the correct one depends on the port thread size on your engine.

Is thread size important when replacing a temperature sender? Yes, the sending unit must match the port thread size on the engine block or head for a proper seal; the TS26611 is machined for a 1/4-18 thread.

Can the TS26611 be used as a direct OEM replacement? It can replace units carrying the cross-reference numbers 362AN-D, 90402, B-936-1, or 52320S004, since TS26611 is the equivalent Sierra part for those numbers.

What is the UPC for the Sierra TS26611? The UPC for this temperature sender is 023121266117.
