Top 20 1994 Chevrolet K1500 Questions & Answers

Generally, Which system had the most pressure when the leak occurred? If the oil system had the most pressure, at that time, then it makes sense that you could get oil in the cooling system with no antifreeze in the oil. Or vise-versa. There may be other variables? Just my 2 cents.

You have a mechanical issue with the transmission. Have a local shop diagnose that first.

K1500 , why skip telling this fact. K2500, k3500 ? we can't just guess. we can not just drive the this truck and know. impossible. post all driving evidence first.are you on ICE ? no road conditions told nor what transfer case option it has. to fix 4wd, one must know the drive train. if not there can be no good help.blind transfer case full Dexron (max#) ATF fluid>? not all leaked or leaking out.

You may have confused more than one run thru the firing order double check your connections maybe it's not locked onto the plug

possible harness and connections transmission could be good but wiring to servos/ solenoids different

Is this a automatic transmission

need vavls seals

Your 20 amp fuse will not blow if glowplug wire shorts. each plug draws 15 amps which is 120 amps total.I think there are in line fuses for them. Try to wring out where each output from the fuse goes, disconnect all and reconnect one at a time till it blows.That should point to your problem process of illumination! Good Luck!!

I would replace the idle air control valve, or at least check the connector and wiring very carefully. If you have a scanner, go to live data when the engine is warm to see if you can read what the valve is doing. There is a test procedure at the link below.

Have your temperature sending unit checked to be sure the computer is taking it out of cold start mode. Most likely it is not working and still dumping too much fuel into the engine and causing the high reading. Think about what I just said, makes sense doesn't it.

its called the fusiable link the orange wire coming from the bat terminal if this wire is soft and easy to bend it is burnt and link is bad wire must be cut out and replaced . do not put a regular wire or the next time it will burn somthing costly replace with 30 amp inline fuse or new fusiable link

First off the thermostat is way to low of a temperature you are wasting fuel. That said you either have a p[lugged heater core (very unlikely) or you have a air temperature control blend door problem.

you can get the gasket for about $20. REmove the pan bolts and it should drop straight down. When you tighten back up make several rounds around the pan tightening bolts so they tighten evenly. DO NOT fully tighten each bolt before moving to the next bolt. if you take itt in plan on paying about $150 to $200.

Not as long as the fuel pump relay is functional.

Call Helm inc or go on line they print all of the factory manuals for the big car companys .You can get them way cheaper then a dealer .With a chevy these things are worth there in gold .

Wow. A snapped side shaft sounds serious. If you lift the front end of the truck, (or the rear end for that matter) the wheels will appear to be counter rotating, it is the way a differential works. If you turn the left wheel forward, the right wheel will turn backwards, and vice versa. When you change to 4wd the front end does make a rather loud clunking sound as the gears engage. You should therefore change while the truck is stationary, then slowly move forward or back until the 4wd engages, then take off. If your truck went OK on ice, it should go as well on pavement, just don't try to engage 4x4 while moving.
