The EVIL ENERGY LS Coolant Crossover Steam Vent Kit is a precision-engineered solution to solve common overheating issues in LS engines, available in sleek red or black anodized finishes to match your engine bay aesthetic. Designed exclusively for LS series engines (5.3L/6.0L LS1-LSX), this kit eliminates trapped steam in the cooling system, ensuring your engine runs cooler, more efficiently, and lasts longer—whether you’re on the street, track, or trail.

1. Precision Compatibility for LS Engines

Tailored to fit all popular LS engines (LS1, LS2, LS3, LS6, LS7, LSX) and a wide range of intakes (Holley Sniper, Pro-Flo XT, Gen 3 Truck stock intakes, etc.). Note: A remote MAP sensor is required for SR1/SR3 Titan intakes, and Gen4 Truck intakes are not compatible—ensuring a seamless fit for most LS builds.

2. Enhanced Cooling Performance

By connecting the front and rear steam ports of your LS engine, the kit efficiently releases trapped steam that traditional cooling systems miss. This improves coolant circulation, lowers cylinder head temperatures, and prevents hot spots—critical for high-horsepower builds or harsh driving conditions (racing, off-road).

3. Easy, Leak-Proof Installation

Pre-labeled driver and passenger tubes eliminate guesswork, while the included installation manual guides you step-by-step. The kit comes with all necessary hardware: AN fittings, PTFE tape, O-rings, and shims—ensuring a tight, leak-proof seal that avoids coolant loss and maintains consistent cooling performance.

4. Durable Build for Long-Term Reliability

Constructed with CNC-machined aluminum manifolds (red/black anodized for corrosion resistance) and 304 stainless steel lines, the kit withstands high engine bay temperatures and coolant exposure. This durability reduces maintenance costs and ensures the kit performs reliably for years, even in extreme use cases.

5. Aesthetic & Functional Design

Choose between red or black anodized manifolds to complement your engine bay’s style—no need to sacrifice looks for performance. The compact design fits in tight spaces, making it ideal for both stock and modified LS builds.

Why Choose EVIL ENERGY LS Steam Vent Kit?

1. LS-Specific Engineering (No Generic Fits)

• Generic steam vent kits often require modifications to fit LS engines, leading to leaks or poor performance.
• Our kit is designed exclusively for LS1-LSX engines, with pre-matched tubes and fittings that fit like OEM—no custom fabrication needed.

2. Complete Kit (No Missing Parts)

• Competitors often sell "partial kits" that require extra purchases for fittings or seals.
• Our kit includes everything you need: manifold, tubes, fittings, PTFE tape, O-rings, shims, and a manual—install right out of the box.

3. Corrosion-Resistant Materials (Built for LS Heat)

• Cheap kits use mild steel lines that rust or aluminum manifolds that corrode in coolant, failing within months.
• 304 stainless steel lines and anodized aluminum manifolds resist high temperatures and coolant damage—built to outlast your LS engine.

4. Versatile for All LS Use Cases

• Works for daily drivers, race cars, and off-road vehicles—unlike specialized kits that only fit one scenario.
• Reduces overheating in both stock and high-horsepower builds, ensuring consistent performance no matter how you use your vehicle.

FAQ

Q: Will this kit fit my 5.3L LS truck engine?

A: Yes—if your truck has a Gen 3 Stock Style Plastic Air Intake. It fits 5.3L/6.0L LS engines (including truck variants) but is not compatible with Gen4 Truck intakes. Confirm your intake generation before purchasing.

Q: Do I need special tools to install this kit?

A: No—basic hand tools (wrenches, screwdrivers) are enough. The pre-labeled tubes and clear manual make installation straightforward, even for beginners. Allow 1-2 hours for a complete install.

Q: Why do I need a remote MAP sensor for SR1/SR3 Titan intakes?

A: SR1/SR3 Titan intakes have MAP sensor ports that conflict with the steam vent kit’s manifold. A remote MAP sensor relocates this component, ensuring compatibility without modifying the intake or kit.

Q: Does the kit prevent coolant leaks?

A: Yes—included O-rings and shims create a leak-proof seal between the manifold, tubes, and engine. We also include PTFE tape for extra security on threaded fittings, minimizing the risk of coolant loss.

Q: Can I use this kit for a turbocharged LS build?

A: Absolutely—turbocharged LS engines generate more heat, making steam venting even more critical. The kit’s 304 stainless steel lines and anodized manifold withstand turbo temperatures, ensuring reliable cooling for forced-induction setups.

Q: What’s the difference between the red and black kits?

A: Only the color of the aluminum manifold differs—both kits use identical 304 stainless steel lines, fittings, and hardware. Choose based on your engine bay’s aesthetic (red for bold looks, black for a sleek, understated finish).
