I wanted to start another thread to ask a more specific question...When removing the front bumper (the whole thing), what considerations need to be taken. Will the airbags be impacted? I honestly don't know what makes them go pop! I dont want them to go pop! when I remove the bumper. Also, what does everyone do with the headlight-washer hoses underneath? plug them, cut them? I didn't see any other peripherals underneath...are there? I don't want to f@*k up anything too badly when removing the bumper. Thanks!

It was relatively simple removing the bumper off my D1. Just a few bolts on the frame and a couple of screws on the side panels, plus disconnecting the marker lights and the washer hose.
I just plugged the hose and shoved it up and out of the way.
Someone will surely correct me if I am wrong, but the airbags are controlled by an inertia sensor that is not connected to (and probably has little to do with) the bumper. |

Actually, i had an ARB put on mine at a dealer and i asked about the air bag. I was told that the stock front end to a D1 has crush points that monitor when there is a front end impact. I dunno, might want to call a dealer and find out. Are you going to put something else on when you take the front bumper off? |

that is how most of the car makers do it. same with the volvo 850 i trashed hitting a deer at 80 mph. airbags did not go off thank god. did not hit enough 'sensors' along the bumper, since i bagged the deer in the legs and the body hit the grill/hood. should have made some nice deer jerky!! i thought the enertia switch was for the fuel system only. what's the real deal? |

I think there were two different systems, but am not sure of which years correspond to which system:
1) earlier discos used frame rail mounted sensors behind the radiator. These still were not attached to the bumper. May have been through 95?
2) later models - 96 maybe and 97 for sure have an inertial sensor mounted in the console under the cubby (I think) that measures deceleration to trigger the air bags.
Regardless, neither system is directly linked to the bumper.

Cool - thanks Garrett.
Bring her to Evans place next weekend.

On my '95 Disco, there are two yellow modules on either side of the truck mounted on top of the frame rails behind the bumper. They seem to be an awful long way away from the bumper, though. The connecting cables run through a yellow convolute tube to the firewall. That yellow color is a great indication that you're not working on your temp gauge sender or some such.
I'm not aware of the location of the sensor for the inertia fuel pump cut off, is it mounted at the switch beneath the bonnet?

would like to, but she just bought a store down the street from my office and is super busy getting it going. trying to get her to do some things to the truck. she is not liking my ideas. damn her!!! it's a bone stock DII. i think if i get her drunk enough she would let me. she's pretty cool. married and all too, but her husband seems cool with the rover stuff. her mother has 2 discoverys and a RR. damn!! |

Garrett,
"i think if i get her drunk enough she would let me. she's pretty cool"
Huh - how'd we get on that subject already! 
Paul,
Those are the SRS sensors - but they do not need to be on the bumper - they are there to sense force, not impact. If the sensors were mounted on a bumper, there is a high likelyhood that the'd get cut or destroyed before acitivating the system. Also, it would probably make it too sensitive for practical use (my guess anyway).

Agreed Bill. Placing them that far back insures that the shock wave would have to be transmitted with sufficient intensity the distance back from the bumper. I don't know what the characteristics are for shock transmittal of a folded piece of sheetmetal with a weld down the center, but I'm sure the fellows in Solihull were able to accurately estimate the amount of force needed to exceed the threshold of the sensors was sufficient. Then, some statistical analysis, and voila, air bags! |

The inertia fuel pump cut off is located in the passenger side engine compartment between the washer bottle and the engine on the Series 1. Your flashers will stay on when it it tripped and it has been known to trip while off-roading. The reset button is on top.
