Breeze Constant-Tourque Clamping System: Virtually all rubber hose compresses "cold flow" after installation of a clamping device, resulting in an almost immediate torque loss that can exceed 80% of installation torque. Similarly, virtually all metal connections expand as a system heats up, and then contracts as the system cools. Conventional worm-gear, T-Bolt, and other clamps are passive, in that expansion and contraction of components cannot be compensated for without retightening or loosening the clamps. The Breeze clamping system is an "active" clamp mechanism, which monitors and then compensates for the temperature changes by actually changing diameter through a unique worm-gear Belleville assembly.

Samco Xtreme Silicone Hose
Samco has a wealth of experience and expertise in Performance Automotive Silicone Hoses. The quality of Samco hoses has been proven by continued success in supplying many top racing and rallying motorsport teams including:
The Samco blue silicone hose with Breeze Constant-Torque clamps Kit is a permanent fix for the PHH Achilles heal. The specs far exceed that of OEM and generic heater hose and clamp capability (not to mention Gates Green Stripe hose). They failed once, they will fail again. Why take the risk? For around $15 above what you would pay for normal hose and clamps (not to mention the cost of your time), you have a solution that will hold up to even the most extreme environments, last the lifetime of the vehicle and will be delivered to your door quickly. Is it overkill? Maybe for mall Cruisers. But if you crawl in Moab, your Birfs should be the only thing you worry about. It’s what known in the aerospace industry as having "MARGIN". Available Samco Xtreme Silicone improves on the already legendary Samco name. The Xtreme edition offers increased temperature operating range and durability over the Samco Sport hoses offered for ultra hard core applications.
The 1FZ-FE Pesky Heater Hose (PHH) is a notorious legend in 80 Series Land Cruiser circles. It's a 50mm vulcanized rubber time bomb that Mr. Toyota decided to locate in one of the most inconvenient, yet still accessible and serviceable location on the vehicle... Hence the name Pesky Heater Hose.
The PHH is a critical piece of cooling system hose that can fail anywhere between 60,000 and 180,000 miles and leave you stranded due to lack of coolant wherever you may be, from the Mall to Moab. While visual inspection will nicely tell you how the outside of the hose looks, failures usually happen from the inside where years of high heat engine compartment environment and hot coolant flow takes it's toll. Properly maintained cooling systems will generally prolong PHH life, but if you haven't owned your Cruiser since new, there is no telling what was put into the radiator and how often.
The scary PHH above right was on my 155K mile 1995 FZJ80. The OEM PHH is black with cotter pin style clamp. This hose was standard generic cheap heater hose and generic cheap clamps. Obviously the OEM hose was replaced at some point in time (not documented by the Previous Owner). Concerned after seeing the condition of the hose, I believed it still had some life in it as it was the second PHH on the vehicle. A week after the photograph was taken, the PHH failed 180 miles from home on my friend borrowing the Cruiser to tow a trailer.
Knowing that the PHH is a very difficult and time consuming maintenance item, I wanted to replace it with hose and clamps that was engineered as well as the rest of the legendary Land Cruiser and replace it with something that would last the life of the vehicle...

The Xtreme Samco Sport Silicone Pesky Heater Hose kit with 2 Stainless Steel Breeze Constant Torque Clamps. $30 plus $3 standard US shipping. Hard Core Permanent Solution for the Pesky Heater Hose.
The 5/8ths (16mm) Samco Xtreme hose is manufactured by hand using steel mandrels. The mandrels represent the inside shape of the hose. The composite rubber/fabric material is wrapped around the mandrel in a number of layers (plies) and thickness. When fully wrapped the hose is treated to a high temperature vulcanising treatment. This produces a fully composite structure with all the separate plies melding together. The vulcanised hose is removed from the mandrels and treated to a final curing process. Eventually the hose is sent to the inspection department for final finishing quality control. All Silicone hose is not created equal. I have tested many brands, some expensive and some cheap. Nothing comes close to the quality of Samco and nothing comes close to the flexibility it offers to get the hose in the tight PHH location... also very important. You can see the difference in the quality of the Samco Sport and Sport Xtreme compared to the prevalent cheaper generic silicone hose advertised all over the net.
