1994 Buick Regal. Can't figure out where the orifice tube is! 3800 actually a Gran Sport

Hi there. This answer is on previous question -->> temperature_cooling_sensor_located

For 3.1L and 3.8L engines, remove the air intake duct or intercooler-to-intake manifold tube, as applicable.

Hope this helps (remember to rating thia free answer).

Clunks by itself without you putting it into gear? Be more specific,please. don-ohio

under your driver side knee panel

i call it the primary fuse/distribution box but what its would officialy be called in the dealer ??

I would check the bulbs, I just had a Cadillac with the same problem, the bulbs looked good, but both were actually bad.

Brake light switch. Should be against brake pedal arm under dash. May be loose or need adjusting.

NOt an expert but my guess is no. First an airbag uses essentially a powder charge to deploy the airbag. Installation and removal is not recommended for joe shade tree mechanic,it can be dangerous. Secondly all that installation has to have a place to mount and a spot inthe dashboard through which it can deploy. Chances are it if didn't come with one an airbag would have no place to "live". If it is even possible to have it done it would probably approach 50% of the value of the typical car that age. Good luck.

follow the upper radiator hoseto the engine, their sould be your thermostat

There's a switch in your steering column. must be replaced

Check copper nut and stud on main connection to fuses on left inner fender. If need be use a metal washer to move nut to good thread area since thread gets worn due to soft metal.
