You would look on the right hand side of the block just below the cylinder head. There you will find the engine block serial number, within those numbers you will see either 318 or 360.

Need to be more specific

I am going to assume that by water inlet, you mean thermostat housing. If the new gasket is a paper like material then by all means do so. Don't over do it, just a ultra thin coat on both sides to make it stick to the surface of the housing and /or engine. If it is paper like with a rubber o-ring inner flange than no. Final note, ensure that you purchase the correct tube of permatex (High Temperature) the back of the package will state (water pump/thermostat).

No. The D designation in the model means that the vehicle is 2WD. If you're looking for a 4WD of the same vintage, the model code would be W-100.

First take a flat bladed screwdriver. Approximatley 3 inches long. Then insert into the ignition. With some force (but not too much) take medium sized hammer and hit the end of the screwdriver (but remember not too hard but you should hear a little cracking sound) that means you broke the detent which normally holds the key in the ignition. Move screwdriver in a up and down motion to release the spring tension. Then give screwdriver three more hard taps with hammer. You should hear what sounds like a spring drop into the steering column. A pair of vice grips and remove screwdriver from key slot. Get what is called a Chinese slide hammer (just ask for at your local parts store) screw into ignition slot. With a good amount of force slide the hammer back several times and the ignition cylinder should break free.

Trust me I have have used this technique several times and it works like a charm.

i just took an 85 d150 with a 318 apart and the number 4 main bearing cap was cracked completely in half but still together like a puzzle piece. it didn't even nock but it lost oil pressure after warm up and the oil got dirty real fast after it was changed. i went to the junkyard today and pulled a number four main bearing cap off of a 1990 d150, everything matched up perfect on the crankshaft and bearing side but the cap was taller which would add strength to the cap where mine broke... idk if it is going to work in mine but i would think that if they changed it in 5 years it would be because that was a common problem.

230 horse power

same way you remove any engine, unbolt from the trans, unhook wiring, undo motor mounts, take the radiator out, hook up cherry picker or block and tackle, and pull the engine out.

i used 2 chains, bolted to the engine mount bolt holes on each side, and the other chain, one end to the alternator bracket bolt to front of block, and the other end to the last bolt on the exhaust manifold

It is either a 22 or 30 gallon tank.

bad voltage regulator, should not go passed 14, should not go below 12

18'

Drivers side, side of trans just below skift linkage.just unplug,screw out old and replace.

Well that depends on your engine and wether it is a long bed or short bed truck.Here are the specs 1986 long bed 14.6,short bed 15.6.1987 short bed 14.8, long bed 17.4 .These specs are the same for the other years except the 1986 is different. The 88 and above to 93 should be the exact same unless the truck has the b2600 engine where the specs are different long bed 17.2 and the short bed 14.6 gallons.This should be what you want to know the how many gallons of gasoline it holds.

Factory equipped tire size will be indicated on driver's door jamb sticker. My '85 d100's sticker says the size is 205/75/15.

235/75r15 will work with almost no difference on speedo gauge
