This SAE Standard describes electric immersion engine preheaters for use in the coolant jacket of heavy-duty and intermediate size diesel engines. This document gives the dimensional information of the four basic styles of engine preheaters. The tables for each style will list the wattage commonly used.
Small engines that typically require less than 600 W of preheat for cold weather starter are not covered by this document. These types of engines generally have very little space available to accommodate an immersion heater of the styles presented in this document.
The purpose of this document is to establish commonality of engine preheater designs. The user of this document can use these current styles and wattages early on in their designing. This will give the user of this document a good engine preheater design.

The Common Tests Technical Committee (CTTC) is part of the Construction, Agriculture, and Off-Road Machinery (ConAg) Council. The CTTC is responsible for standards related to the design, development, and application of specific tests of machines, components, and systems. The committee develops SAE Standards, Recommended Practices, and Information Reports in accordance with the SAE Technical Standards Board (TSB) Rules and Regulations. These documents are harmonized with comparable International Organization for Standardization (ISO) documents, where possible. The liaison is with ISO/TC127/SC 1. The CTTC is comprised of three subcommittees and a task force dedicated to creating, preparing and maintaining all relevant specifications, standards, and requirements for common tests. These subcommittees include: CTTC SC1 Hydraulic Systems CTTC SC2 Electrical Components & Systems CTTC SC4 Cold Weather Operations CTTC J180 (Electrical Charging Systems for Off Highway Work Machines) Task Force Participants in the SAE CTTC committee include OEMs, suppliers, consulting firms, government, and others across the construction and agriculture industries.
