Chevrolet

i have a 1988 motor home i need to know where heat sendig unit is located so i can add real gage please help RIJOEE

Mounted on top and inside the fuel tank.

Need to know the year and engine size and what it is in.

On ALL trucks in '76 and '77, whether single OR dual tanks, the fuel gauge wire (tan) comes from the main bulkhead connector at the firewall & routes through the engine wiring harness: it follows the starter wires through the heat shield tube by the RH exhaust manifold, then branches off & is clipped on the inside of the RH frame rail & ends at the RH fuel tank. Wire has the round rubber "push-on" connector. This wire is the same length on all trucks because it's part of the engine wiring harness -- GM did this to minimize the number of different engine wiring harnesses they had to make.

This tan wire plugs into the RH tank sender on 1-tank trucks. On 2-tank trucks it plugs into the dual-tank wiring harness instead.

The dual-tank harness plugs into a round grommet in the firewall just to the right of the distributor cap area (if you have a V8) This harness goes straight down & follows the LH frame rail.

The blue wire exits the harness first & attaches to the the LH tank sending unit.

The harness crosses over to the RH side & ends close to the selector valve. The green wire goes to the selector valve.

The tan/white wire attaches to the RH tank sending unit.

The tan wire attaches to the fuel gage wire discussed above.

It sounds weird but yeah, that tan circuit does make one big loop around the whole front half of the truck. If you are wiring from scratch you can cheat & just run the tan wire from the back of the fuel gage directly to the tan wire on the fuel tank selector switch.

The switch sends power through the green wire to the selector valve when it's at the LH position.. so if the unit goes bad, you will be pulling from the RH tank.

Dual-tank wiring setups changed several times from '73 to '87 so this only applies to the earlier trucks. Not sure when the changeovers occurred.

Did you remove the big snap ring that's inside of the hub. It's hard to see.

Hi, Let's start by opening the tail-gate all the way down . Then lift the tail -gate until the arms on the sides are half open . Then lift up on the arm towards the top of the bed side until the opening in the arm where it attaches to the tail-gate allow's the arm to be removed . Do the same for the other side .Once both arms are taken off , slightly lift the tail-gate off the the truck by pulling up and to the right ... Hope this helps ...

Need to know the year.

Check conections on the o2 sensors . Replace the 02 sensor.

It means nothing, but is instead the last name of the founder of the company. Chevrolet comes from the man who founded Chevy, Louis Chevrolet.

both motors have a 3.875 bore size but a 250ci has a 3.530 stroke where a 292ci has a 4.120 stroke and was used in trucks only

1985

Camshaft position sensor is on the front of the engine behind the belt(s) and wheely things. You'll have to get to it from under the front of the truck - but it sits on the engine front side, maybe 8 inches towards the driver's side from the center of the engine and about 1/2 way up the engine. It's 1/2 white and 1/2 black, has a wiring harness run to it from the bottom. Takes a 10mm bolt; be careful not to strip it putting it back in; once you find it - takes about 5 minutes to swap out - easy job once it's found!

it should be 1 ton including the weight of you and a passenger but you can usually haul a little bit more but to be safe 1 ton! 2000 lbs

5 quarts with a filter change. 4 quarts without filter change.

Type A transmission fluid in the automatic

You did not SAY what you were CHANGING. NEUTS

Does it leak antfreeze or if it does not spin freely or it might be loose and slopy

The 409 was a 348 bored .187 over. The 348 was 4.125 x 3.25. The 409 was 4.312 x 3.25

It is behind the starter, Will need to remove starter to service it.

the sparkplug gap on an 04 chevy optra is 0.032

Move the switch until it opens the contact when the brake pedal is pushed down 1/2".

Resistor pack on blower motor? Fan switch? Low speed relay?

The speakers at the rear, in the headliner of 1996 Tahoe are 4x10's. They are an odd size that only GM uses/used but with some work you can usually find some replacements (I found some pretty decent ones at Wal-Mart about 8 years back when I replaced mine)

There are really only two logical possibilities for an inline 4 where the crankshaft is supported at the ends; 1-2-4-3 and 1-3-4-2. It has to be one of those two firing orders. Ford used 1-2-4-3 so more than likely your Chevy engine is 1-3-4-2. Try that and if it does not run try the other one.

You would have to take off the electrical wires that are intact, fuel hose water temperature wires. take off the carburetor, distributor make sure you know the firing order to put the distributor and ignition wires back to prevent an easy start. Take off the intake manifold, take off the valve covers take off the roller rocker arms, pushrods, make sure you inspect them for signs of wear or damage, and mark the roller rocker arms and pushrods to which cylinder and location and place they are going back on when you're reusing them. But if you're replacing them you don't need to put them in the exact place. Lastly take off the cylinder heads, the bolts on the top will be bigger and the bolts on the bottom will be smaller. Coolant goes through the smaller bolts. After that take off the heads and inspect for wear and damage. You must clean the surface of the cylinder heads, clean valves and clean the area where the cylinder head sits which is the engine block. Make sure you use the proper head gaskets and make sure you put them the right way and torque them to whatever torque spec they are. Thank you.
