Volvo Penta 3852029 — Single Station Temperature Sender | 1/2 in. NPT
Volvo Penta 3852029 is the OEM single station engine temperature sender. It mounts in a 1/2 in. NPT port and sends a signal to your temperature gauge via a 10-32 stud terminal. Designed for use with US ohm scale temperature gauges. This is a single station unit — if your dash uses two gauges reading off one sender, you'll need a dual station sender instead.

Frequently Asked Questions
Q: How do I know if this is the right temperature sender for my engine?
A: Check the fitment list above. If you're still not sure, send us your Volvo Penta engine model and serial number and we'll confirm it for you — by email, text, or live chat.
Q: What's the difference between single station and dual station senders?
A: A single station sender sends a signal to one gauge. A dual station sender sends a signal to two gauges from the same sender, which is used on boats with dual helm stations or a matched pair of gauges. The 3852029 is single station only.
Q: Will this sender work with my existing temperature gauge?
A: This sender is designed for US ohm scale temperature gauges. If your gauge uses a different scale (such as European/SW), it won't read correctly with this sender.
Q: What thread sealant should I use when installing this sender?
A: Use a thread sealant rated for engine coolant service, applied per the instructions in your Volvo Penta service manual. Avoid overtightening, which can crack the sender housing.
Q: Does this sender include the stud terminal connector?
A: The sender includes the 10-32 stud terminal itself. Confirm your existing wiring harness connector is compatible, or contact us for guidance.
