Buick Roadmaster

Under the vehicle, passenger side, 2 feet in front of the rear tire, just inside the frame.

I would guess that the thermostat is not opening at the proper temperature. Once it does open proper circulation brings it down to the correct operating temperature. I think it should be replaced.

It's the Flow Rate

Inspect the driveshaft, look for dents, undercoating or buildup, or driveshaft or companion flange out of balance, check for missing weights on shaft. Try removing driveshaft and reinstalling 180 degrees different.

The first step is to find a single Phillips screw hidden in the carpet on the lower rear side of the panel. It is approx 5 inches in and 4 inches up. Remove it. Next, peel each end of the grab handle inward to reveal a single large Phillips screw (1 per side). Remove the screws. Next remove the single screw behind the interior door handle and remove the door handle surround over the hadle itself. the rest of the fasteners are snap type. Start at the bottom using the special door fastner tool to release. You can just pull forcefully, but it usually breaks these fasteners. Once the door is only hanging from the top strip, remove all elecrical connections. Next roll down the window and pull upward on the panel to release it from the lower window strip. Installation is reverse of removal.

is that 'rest' or 'reset'? If by 'rest' you mean to give the AC unit a rest, that's a good idea, all roadmasters from 92-96, when you start the car, if the ventilation was switched on last time, the AC comes on by default, even if you had the heat on to 75f say. This sucks the gas. When you start your roadmaster, either hit the 'econ' button quickly to turn the ac off, or press the 'off' button before you turn your engine off. The next time you start it, the ventilation will be off.

If you mean reset, well, I changed my battery, and the ventilation panel readout seemed to cycle though 32f to -20f or so a few times, then started. id say that reset it!!!!!

Your battery might be dead or very close to dead. If the interior lights come on but go dim when you try to start then the battery is probably dead. Otherwise, get a new starter.

1 of 2 things or both, alignment or balance.

The 70, version. 160, to 180. The 90's version, 180, to 210.

Yes, you need GM-style fuel quick disconnect tools. One size fits the outlet line, another size fits the return line. I got mine at Advance Auto parts. Do not get the combination tool with both sizes on the same tool. This will work on a GM truck, but not on a car. Don't know why, it just is.

You will not find it on the engine. It is mounted in the fuel line between the fuel tank and the engine. Look and you will find it.

No! Thermostat.

SIMPLE. Pull the rubber boot/air connector off the side of the Shock. The problem with the system is a small solenoid valve on the compressor. Easiest thing to do .................... JUNK YARD replacement

The value of a vintage Big Red Wagon by Radio Flyer can vary significantly based on its condition, age, and any unique features. Generally, prices range from $50 to several hundred dollars, with well-preserved or rare models fetching higher amounts. Collectors often seek out specific models or those with original paint and components, which can increase their worth. For an accurate valuation, it's best to consult recent sales or auctions of similar wagons.

700 R4, the better way to tell is when the down shift cable is no longer present the transmission shifting is computer controlled 4L60E which is a more complex (computer controlled) version of the 700 R4. I looked at a 92 today and it had a 700 R4.

Wow

Tough job. I replaced all the shocks on my 95 Estate Wagon about 2 years ago. The front shocks were fairly easy. But the rear shocks were very difficult. I had help from a friend who is a professional mechanic, access to his tools and we had the car up on a lift. It took the two of us almost 3 hours to change the shocks. With four hands squeeezed in around the exhaust pipes and wrenches with flexible heads, we finally got the top shock mounts installed and tightened. I was never able to find out if there was a hatch under the back seat to get to those upper shock nounts. It would sure help. I hope to never do the rear shocks again!

Good luck

The "auto" button above the vent button is the A/C. Turn your temperature to 60 degrees and right next to that button is the "auto" button. Hit it and the air should come on

If it's a Roadmaster it is usually easier to follow the centre wire running from the distributor cap. I have a 92 and its at the back next to the distributor. It has only one plug in connector however it is 2 connectors put together to look like one plug.They have to be put together first before you plug back into the coil once you have removed them.

The Buick Roadmaster was not produced in 1986. They were made from 1991 to 1996.

Sell It!!
