Default 94 5.0 Lost power.

So I've been Driving this truck for about 2 months after i fixed the shifter on it. its a 94 150 5.0 5 spd 4wd. I drove it from Vancouver to home. 70 miles. I had 3 das off work and wanted to visit. It ran fine like always driving home. Yesterday, I went out to this place with my friends and they talked me into wheeling it. I cant believe i did. After.. I noticed it was running hot. I opened my radiator cap and lost all my coolant. Drove 2 miles to get some. It was smoking when i got to fred meyers. got coolant and water put it in.. and it was running fine again. Its got a K&n cold air. so some water got sucked up into it. Stupid again. I know. but today i went to builders supply to get some paint thinner and noticed it was bogging down completely when i was driving up hill.. barely even made it.

Things ive done already.

Fuel Filter.
The exahust before the Cats is running 2 Psi.
Vaccum is holding a steady 13-14 psi.


I need this thing running ASAP. I did notice that when i was driving.. it had a vaccum leak type sound coming from it. Sounded like it was by the transmission.. being a stick theres no vaccum lines connected.. but i dont know what else to do

When you put coolant in it did you let it cool off before you put it in. A lot of times people have put coolant in with their engine being hot and it will crack a block or a head. Cold liquid to hot forged steel is not a good mix. Or it could your head gasket has blown between cylinders letting it leak compression. Start engine and take radiator cap off if you see air bubbles you are leaking compression in to your coolant system.

Not necessarily.that's also how you bleed sure out of a cooling system. Be safer to do hydrocarbon test.

Ive done the save thing. Run it capped and see if any lines are leaking. There should be some copper? pipes on the front, and there is a t connection. Thats where mine cracked... And if it gets to warm it wont fire up, so dont panic if it does. Let it cool down and should fire up shortly after
