Critical Fit Note:K-Series Engines Only– Does NOT fit B-series (B16/B18) or D-series (D16) engines. Designed to bolt directly to OEM K-series water pump housings (no adapter plates needed).🔧 3 Versatile NPT Ports – For Gauges, Fans, & AccessoriesThe housing features three dedicated ports to simplify custom cooling system setups—no need to drill or tap aftermarket holes:

• 1/8 NPT Gauge Port: Connects to coolant temperature gauges (mechanical or electronic) for real-time engine temp monitoring (critical for track days or modified engines).
• Fan Switch Port: Accepts aftermarket fan switches to control electric cooling fans—adjustable to your preferred temperature (e.g., 185°F on, 175°F off) for optimal cooling.
• Recirculation Port: Works with optional recirculation fittings (sold separately) to fine-tune coolant flow (ideal for race cars or engines with upgraded radiators).
• Included Block-Off Plugs: 2 NPT plugs are provided for unused ports—prevents coolant leaks and keeps debris out of the system.

🌟 Billet Aluminum Construction – Durable & Race-ReadyBuilt to outperform Honda’s factory plastic thermostat housing (which cracks under heat or vibration):

• High-Grade Billet Aluminum: Lightweight yet rigid, withstands extreme engine bay temperatures (up to 300°F) and resists corrosion from coolant (ethylene glycol or waterless coolants).
• Swivel Neck Design: The housing’s rotating neck lets you adjust the water outlet anglebefore tightening—critical for K-series swaps, where factory hose routing may not fit older chassis (e.g., EG Civic). Eliminates kinked hoses and improves coolant flow.
• Pre-Installed 180°F Stant Thermostat: Features a premium Stant thermostat (industry-standard for reliability) that opens at 180°F—balances engine warmth (for efficiency) and cooling (to prevent overheating). Easily replaceable with 160–195°F thermostats for custom tuning.

🔩 Custom Hose Compatibility – AN Fittings or OEM HosesFlexible enough to work with stock or aftermarket cooling systems:

• OEM Hose Adapter: The included custom fitting has one end matching Honda’s OEM radiator hose size (for stock setups) and a threaded end for AN fittings (for braided hoses in performance builds).
• AN Fitting Ready: Thread the adapter to your desired AN size (e.g., -16 AN for high-flow radiators) to use braided hoses—perfect for track cars needing leak-free, high-pressure cooling.
• Race Car Optimization: Drill one extra hole in the flange to bolt the housing directly to the OEM aluminum water pump (removes the factory plastic housing and heater core hoses)—ideal for stripped race builds where weight and simplicity matter.

4. Installation & Usage TipsInstallation Guidelines

• DIY-Friendly (1–2 Hours): Basic tools (socket set, screwdrivers) are needed. Key steps:
  1. Drain coolant from the engine (follow Honda’s procedure to avoid spills).
  2. Remove the factory thermostat housing and old thermostat.
  3. Use the included steel template to mark holes (if optimizing for race use) and bolt the new housing to the water pump.
  4. Adjust the swivel neck to your desired angle, then tighten the locknut.
  5. Install the custom hose adapter (OEM or AN) and reconnect the radiator hose.
  6. Refill with coolant, bleed the system, and test for leaks.
• Swivel Neck Tip: Align the outlet to point directly at the radiator inlet—avoids sharp bends in the hose, which restrict coolant flow.

Usage Tips

• Thermostat Replacement: For track use, swap to a 160°F thermostat to keep engine temps lower; for daily driving, stick with 180°F for better fuel efficiency.
• Coolant Choice: Works with all coolants (conventional, extended-life, waterless)—avoid mixing different types to prevent corrosion.

After-Sales Support

• Fitment Issues: If the housing doesn’t align with your K-series swap or adapter doesn’t fit your hose, contact the seller with your engine/chassis (e.g., “K20A2 in 1995 EG Civic”)—they’ll provide adjustment guidance.
• Defects: If the aluminum housing is cracked, thermostat is missing, or hardware is stripped, request a free replacement (covered under warranty).

The ultimate thermostat housing for K-series builds! This kit solves factory plastic failures, simplifies custom cooling setups, and works for street or track use—perfect for Honda enthusiasts upgrading their engine or swapping a K-series into an older chassis. 🚗🔧
