Glacier Diesel Power Sure Start Universal Diesel Inline Grid Heater – 12V & 24V (300350-UGH)
Description
Cold-weather starting problems aren't limited to pickup trucks.
Diesel engine swaps, farm equipment, industrial engines, military vehicles, older diesel platforms, and custom projects can all suffer from difficult cold starts when the engine doesn't have an effective intake-air heating system.
The Glacier Diesel Power Sure Start Universal Inline Grid Heater provides a powerful, adaptable intake-air pre-heating solution for diesel engines equipped with 3.00" or 3.50" intake or intercooler piping.
Rather than relying on starting fluid or excessive cranking in cold conditions, the Sure Start heats the incoming intake air before it reaches the engine, helping promote easier combustion during cold starts.
Available for 12V and 24V electrical systems, the Sure Start uses a twin-element heater design that provides substantial heating capability for demanding diesel applications. The twin-element configuration can also be converted to single-element operation by removing the jumper when the application requires it.
Whether you're trying to improve cold-weather starting on a diesel swap, piece of equipment, Humvee, Detroit Diesel, or a completely custom project, the Sure Start gives you a purpose-built way to add intake-air heating almost anywhere you can install it in the intake piping.

Why Add an Intake-Air Pre-Heater?
Diesel engines rely on heat generated during compression to ignite the fuel mixture.
As ambient temperature drops, achieving the temperature required for clean, reliable combustion during startup becomes more difficult—especially on older engines, modified engines, or applications without an effective factory intake heater.
The result can be:
- Extended cranking
- Hard starting
- Excessive battery draw
- Increased starter wear
- Rough initial combustion
- Increased cold-start engine wear
- Dependence on starting fluids
The Sure Start heats the incoming air before it enters the engine, giving the diesel a warmer intake charge during startup and helping the engine fire more quickly in cold conditions.
A Universal Solution for Diesel Engines
The Sure Start isn't tied to one particular truck, engine family, or manufacturer.
If your application uses compatible 3.00" or 3.50" intake or intercooler piping, the inline design allows the heater to be incorporated into a wide variety of diesel intake systems.
Potential applications include:
- Diesel engine swaps
- Farm and agricultural equipment
- Industrial diesel engines
- Construction equipment
- Military vehicles and Humvees
- Detroit Diesel applications
- Older diesel trucks
- Custom diesel projects
- Equipment without an effective factory intake heater
That versatility makes the Sure Start especially useful when you're working with an engine or vehicle where a bolt-on application-specific grid heater simply doesn't exist.
Twin-Element Heating Design
The Sure Start utilizes a twin-element heater assembly to provide substantial intake heating capability.
For applications that don't require the full heating capacity of both elements, the heater can also be configured for single-element operation by removing the jumper.
This gives installers additional flexibility when designing the electrical and intake system around the needs of the engine.
Rather than forcing every application into the same configuration, the Sure Start can be adapted to suit a wide variety of diesel projects.
12V & 24V Applications
The Sure Start is available for both 12V and 24V applications, making it suitable for considerably more than conventional pickup trucks.
That opens the door to industrial, agricultural, military, and specialty diesel applications that may use different electrical systems.
Important 24V Installation Note
For 24V applications, the current Glacier Diesel Power installation requirements call for two separate 12V leads—one from each battery—and two relays.
Proper wiring is extremely important with any high-current intake heating system. Wiring, relays, connections, and grounds should be sized appropriately for the installation.
Built for a Secure Intake Connection
A universal product is only useful if it can be properly integrated into the intake system.
The Sure Start includes the heater assembly and hose flanges featuring Mil-Spec hose beads, helping provide a secure connection between the heater and compatible intake boots.
Depending on the application, additional boots, clamps, or reducers may be required to complete the installation.
Dimensions
- Overall Length: 6.75"
- Minimum distance required between hose ends: 3.00"
- Heater Assembly Dimensions: 4.00" x 5.00"
- Intake / Intercooler Piping Compatibility: 3.00" or 3.50"
These dimensions should be checked against the available installation area before ordering or modifying the intake piping.
Glacier Tech Tip
When planning a Sure Start installation, don't look only at whether your intake piping is 3.00" or 3.50".
Consider the entire installation:
Available space, piping orientation, wiring distance, relay location, battery location, boot clearance, and serviceability all matter.
For wiring runs up to approximately 7 feet, Glacier Diesel Power currently recommends 4-gauge wire along with an appropriately sized heavy-duty starter relay for control.
Because this is a universal product, the installer is responsible for determining the proper installation configuration for the specific engine and vehicle.
Why Choose the Sure Start?
There are plenty of diesel engines out there that need cold-start assistance but don't have a clean, application-specific grid heater solution.
That's exactly where the Sure Start fits.
Instead of designing the heater around one engine, Glacier Diesel Power developed an inline intake-air heating system that can be incorporated into a wide range of diesel applications.
From an engine swap in a custom truck to farm equipment sitting outside during winter, the goal is the same:
Get heat into the incoming air and get the diesel started.
Purpose-built. Adaptable. Cold-weather capable. Engineered by Glacier Diesel Power.
Applications
The Sure Start is a universal product suitable for many diesel applications using compatible intake piping, including:
- Diesel engine swaps
- Agricultural and farm equipment
- Industrial diesel engines
- Construction equipment
- Humvee and military vehicle applications
- Detroit Diesel engines
- Older diesel trucks
- Custom diesel projects
- Other diesel applications using compatible 3.00" or 3.50" intake piping
Because this is a universal product, fitment and installation requirements must be verified by the installer for each individual application.
