Hey guys just wondering if anyone knew where to find the radiator drain plug as I am looking to flush my system. Thanks

I couldn't tell from up top. If all else fails and you can't find it, just pop the lower radiator hose. of course then all the water would come rushing out with little hope of containing it all.

Replying to: hoodlatch (Nov 06, 2006 9:39 am) I blocked up the bottom of the door with wood blocks to support everything while I drove out the old pin. Pops helped me with free advice, holding the droplight, and wiggling the door when needed. The replacement pin and bushing fit perfectly. The tricky part was getting the spring back in. It would be faster if I had use of a spring compressor but I didn’t feel like renting or buying one. What I did to overcome the lack of a spring compressor was to compress the spring in a vice, took a wrap through the spring with stainless steel wire, and used needle nose pliers to twist the wire tight. That held the spring compressed enough that I could use a screwdriver to get the spring poked back in where it belongs. After that I used a pair of dikes to cut the wire loose and wha-lah, job done. I was happy to see how well it all went. No skinned knuckles, pinched fingers, cursing, or throwing objects. Now my door opens closes like it should with out a hitch. We’ll probably do Dad’s S-10 next. I think the total cost for parts (pin and bushing kit) was less than five bucks. Total time for Pops and I from start to finish was probably around 45 minutes to an hour. A technician that does this kind of work for a living could do the same job in half the time.

I have replaced the plugs, had the throttle body ckecked, and had the electrical system ckecked. So far I have found nothing. Any ideas welcome. Unless you are having the exact same issue and have done the exact same things, I would try just posting your exact issue. That way you can recieve more direct advice instead of more generic advice. So without knowing exactly what it is that you are having a problem with here is some generic advice... It sounds like it might be either a fuel filter or a fuel pump. I would lean more towards a fuel pump rather than a filter, but try changing the filter first. It is by far cheaper and easier to do and should be done every couple of years or so anyway. See if that helps. You could aslo be losing fuel pressure in the lines. Even with the truck off the fuel lines remain pressurized and fuel delivery to the injector is instant the minute the starter is turned. If you are losing fuel pressure when the truck is turned off, it will take several cranks of the starter and the fuel pump to deliver fuel back to the injectors. Once the truck is running a fuel is flowing, then you're good to go, but the minute you kill the power to the pump (turn the ignition off), then you lose all pressure and you're back to square one. The pump is what maintains the pressure (even when the truck is off) and so it is possible that the pump is allowing the pressure to bleed off over a matter of time. Which would explain why an overnight sit or even a 30 minute sit would induce hard starting. This is the direction I would point you in. There are a couple of ways you can test this. On your truck (depending on motor size - 2.2 or 4.3. I only know the 4.3) there is a schrader valve on the fuel line next to the throttle body. This is where you can bleed off the fuel pressure (so that you can change the filter with out getting sprayed by fuel. Trust me, if you do change the filter, BLEED OFF THE PRESSURE! It sucks getting sprayed by fuel while lying underneath the truck.) Anyway, to test, pull the dust cap off the valve and stick a pressure gauge (available at an autoparts store like Shucks or Autozone), and check the pressure. Then come back a few minutes later and check it again. It should read about the same. If the pressure is quite a bit lower than the previous reading, you probably have a pressure problem. You can also test this with out a pressure guage, but you will probably get a bit smelly. At the schrader valve take a container and some rags to catch the spilled gas and hold it by the valve. Depress the pin taking care not to have your face over the valve as you do so to relieve the pressure. Do this immediatly after the truck has been running for a couple of minutes. Long enough to build up the fuel pressure, but no long enough to get the motor so hot that you can burn yourself on everything under the hood. Once all, or most of the pressure is bled off, start the truck again. It should be hard to start. Then let it run for a couple minutes like before and then shut it down. Let it sit for a while and then come back and WITHOUT starting the truck, repeat the process with the rags and container. If you have a pressure problem, there shouldn't be a whole lot of gas spewing out of the valve. So first and foremost, change the fuel filter. It isn't hard and something you can probably do yourself. By going through the process you will invariably discover whether or not you have pressure in the fuel lines because you should be bleeding off the pressure anyway so that you don't get sprayed with you release the lines connected to the fuel filter. If you do find that you have a pressure problem, then you might have a bad pump, but not neccasarily. You could also have a bad or loose vacumn somewhere in the that is also allowing pressure to bleed off. From there I'm afraid I am not much help. Changing a a fuel pump isn't hard, but it isn't fun. Depending on your mechanical expertise, you might just want to take it to a shop. They might also be able to run some diagnostics to determine whether it is the pump or something in the fuel lines.
