Note: Hose from Hell is also known as HFH.
Description of HFH:
The HFH is a simple 5 inch coolant hose on the MR2 Turbo that usually wears out and burts sometime after a car hits 100K miles. The symptoms of a bad HFH are low or no heat coming from the heater vents, water dripping under the engine near the exaust, and finally, a full burst will result in smoke clouds billowing out from under the engine compartment, and high temps. Sometimes people think they've blown a headgasket, but if you look under your car, and directly under the downpipe and exaust, there is water, it's very likely to be the HFH. It is a major pain in the ***** to fix without taking the exaust manifold off of the car, but it can be done in a few hours if you have patience, the right tools, and not overly large hands (borrow a kid from the neighboorhood to help!).
The HFH itself is made out of heavy duty rubber hose with a thin heat barrier shell with 3 outer clamps. The center clamp helps keep the heat barrier on and stop expansion of the hose, and the two clamps on each end hold the HFH to a metal coolant hose, one coming off of the Oil Cooler (which the oil filter bolts onto), and the other to a pipe called the Water Bypass Pipe that leads under the Exaust Manifold. It has a sister hose known as the Hose from Hell on Earth or HFHOE. The HFHOE connect to the Oil Cooler on the passenger side, and should be unclamped in order to remove the oil cooler for access to the regular HFH.
Cost of HFH replacement at the dealership = PROBABLY HUNDREDS OF GPB's!!
Cost of fixing the HFH yourself = My guess well under $50 GBP's
[b]DISCLAIMER[/b]
We do not recommend replacing the HFH and/or HFHOE unless you are determined, have small to medium hands, are able to work in awkward positions, have patience, are willing to buy any needed tools and parts that you don't already have, and finally, ENJOY WORKING ON YOUR CARS!
We have to put a disclaimer on this one, because you can scrape/cut your hands, break or strip out parts, and possibly go insane! Please attempt this only if you are of sound mind and body, and of your own free will.
I can go into the how if need be
