A step-by-step guide to fitting the PLM Power Driven Tucked Radiator XL on Honda and Acura builds, covering clearance checks, hose routing, fan wiring, and bleed mistakes.

Quick answer

Fit the PLM Power Driven Tucked Radiator XL by test-fitting it before you commit to hose or fan placement, then route hoses with the core fully seated and bleed the system with the front end raised. The XL adds cooling capacity, so clearance and hose length matter more than with the standard tucked radiator.

Why the XL changes your fitment plan

The PLM Power Driven Tucked Radiator XL is an extra-large version of the standard tucked radiator, intended for builds that need more cooling capacity. That extra capacity comes from a larger core, so the space you gained by tucking the radiator may be tighter than expected. Measure before you order, and plan hose routing around the final core position rather than the factory radiator position.

Because the XL is designed as a direct replacement for the factory radiator, the mounting points should line up, but accessories such as fan shrouds, intake piping, and battery trays may need attention. If you are unsure whether the XL fits your chassis, compare your current radiator core dimensions and outlet positions with the PLM unit before installation.

Installation steps for the PLM Tucked Radiator XL

Test-fit the radiator before connecting anything: With the old radiator removed, set the PLM XL in place and check clearance to the fan, intake, and front support. Do not tighten mounts until you confirm the core sits flat and the outlets point where your hoses can reach. If the core contacts anything, stop and adjust before adding coolant.
Mock up hose routing with the radiator seated: Attach your upper and lower hoses loosely and check that they clear pulleys, belts, and the fan. The XL's larger core can push outlets closer to accessories, so trim or replace hoses as needed rather than forcing a bend. A hose that kinks or rubs will fail; route it before you fill the system.
Mount the fan and confirm wiring clearance: If you selected the with-fans option, install the fan on the radiator and check that the motor and wiring clear the core and nearby components. Secure wires away from heat and moving parts. Spin the fan by hand to confirm no contact before powering it.
Fill and bleed with the front end raised: Fill the system slowly with the front of the car elevated, run the engine with the heater on, and add coolant as the level drops. Squeeze the upper hose to help move trapped air. Do not cap the system until the lower hose warms and the level stabilizes.
Pressure-test and check for leaks after a heat cycle: Let the engine cool, then pressure-test the system and inspect hose clamps and the radiator drain. Recheck coolant level after the first full heat cycle. A small leak at the outlet can worsen; fix it before driving hard.
