The SPOOLOGIC Turbo Coolant Feed Line Kit SL-360-003 is a direct-replacement turbo coolant feed line for 2017-2019 6.7L Powerstroke applications. Built to OE form and fit, it carries coolant from the block up to the turbo center section using rigid steel tubing joined to a flexible hose section by two constant-tension spring clamps, and terminates in a flange-style fitting with a pre-installed O-ring that seals the line to the turbo coolant port. Backed by a 1-Year Limited Warranty.

Why You Replace the Coolant Line — Not Just the Hose

Coolant lines, jumper hoses, and their seals are not designed to be reused forever. Here’s what’s actually happening to the parts you’re tempted to put back:

• OE coolant lines corrode and crack from the inside out. The steel tubing runs coolant through the hottest zone of the engine bay, cycling from cold soak to 200°F+ operating temp thousands of times. Internal scale and external road salt eat the tubing until pinhole leaks show up at the crimps or the bends.
• Rubber jumper sections harden and split. The flexible hose section between the rigid steel and the turbo sees the same thermal cycling and eventually goes brittle. When it splits, coolant sprays across a hot turbo — sometimes onto the exhaust manifold — and the truck overheats fast.
• Spring clamps lose tension. The constant-tension spring clamps that hold the rubber jumper to the steel line lose their preload after enough heat cycles and start weeping at the hose ends.
• Coolant-line O-rings are single-use. The O-ring at the turbo-side flange takes a permanent compression set the moment it’s torqued down. Reused O-rings weep coolant onto the turbo center section.

Component Breakdown — What Each Piece Does

• 1 rigid steel coolant feed line — formed steel tubing bent to OE geometry so it clears the surrounding components and drops into the factory routing.
• 1 flexible coolant jumper hose — pre-installed on one end of the steel line with two constant-tension spring clamps already crimped in place.
• 2 constant-tension spring clamps (pre-installed) — hold the rubber jumper to the steel line at both ends of the hose section.
• 1 flange-style turbo-side fitting with pre-installed O-ring — the flange bolts to the turbo coolant port and the O-ring seals the joint against coolant pressure.

Material Technology — Why Each Material Was Chosen

• Rigid steel tubing — the line body is formed steel to OE geometry and welded to mounting brackets in the correct positions so the line clears the surrounding components and drops into the factory brackets.
• Coolant-rated flexible hose section — the jumper is coolant-rated hose designed for the thermal cycling and vibration this line sees in service.
• Constant-tension spring clamps — the clamps are the correct spring rate to hold hose preload as the rubber expands and contracts with temperature, so the joint stays tight through every heat cycle.
• Pre-installed elastomer O-ring — correct material and durometer for engine-coolant temperatures, sized for the flange groove so it seats without rolling or extruding.

Install Notes

• Drain the cooling system before removing the old line — open the radiator drain and catch the coolant in a clean pan for reuse or disposal.
• Clean the turbo coolant port mating surface with a plastic scraper and a lint-free rag before installing the new line. Old gasket residue, coolant crust, or scale on the port will keep the new joint from sealing.
• Inspect the pre-installed O-ring before setting the flange down — make sure it’s seated in the groove and not pinched. Lightly wet with clean coolant so it slides into the port without rolling.
• Follow the Ford service manual torque specs for the turbo-side connection. Over-torque cracks the aluminum port; under-torque leaks.
• Route the line through the factory brackets and clips — the tubing was bent to clear specific components. Skipping the brackets lets the line rub through under vibration.
• Refill with the correct Ford Motorcraft specification coolant, bleed the system per the service manual, and inspect the line at every fitting after a full heat cycle.
