weird overheating issues. coolant bursted out of the rear???

[koa's93ranger]

ok. so today i was driving home from work. everything was fine, temp guage was just where it usually is. when i shut my truck off, there was a massive amount of coolant pouring out from under my truck. assuming i blew a hose, i popped the hood. but odly the coolant was shooting out from the rear of the engine, right by the firewall. it WASN'T coming from a seam, as if it were a blown head gasket, but instead out of some aluminum hose coming from the rear of the engine, facing downward, aiming right at the top of the tranny. any ideas of what this could be and how bad this situation is? im in a bind right now as i just started a new job 3 days ago and am in desperate need of transportation.

i would love to show you a picture of what im talking about but its too tight of a sport to get a camera in. can anyone provide a picture of a 4.0 from the rear?

thanks for any help you can provide

Here's a picture for you. that's a 1993 4.0 I have laying around. I've never seen a aluminum hose on the back of a 4.0. maybe you have something aftermarket. trace the hose and see where it goes

 

[koa's93ranger]

anyone else got any ideas of what this could be? id hate to pay the dealership hundreds of dollars to tell me that its something minor.

That aluminum piece doesn't happen to be one of the tubes from the heater core...

That's the only aluminum tube I know of in the cooling system. Maybe it blew off and flew behind the engine.

Are there still 2 hoses going into your heater box?

 

[BlackBII]

I was going to ask the same thing.

Should be two hoses going into your firewall, heater hoses.

Maybe one of them came loose?

 

[koa's93ranger]

i know for sure its not the heater core because i just bypassed that 2 weeks ago because the heater core is no good and needs replacement. i was told by a mechanic that its possible that it could be a freeze plug or that the coolant is coming from my intake manifold. he told me to pour water into the radiator and see where the water comes out of. with the little room and all the oil caked up on the rear of fthe engine, i wasnt able to find the exact location of where the coolant is coming from, but i have a general idea (noted in the photo).

what is that circular part? is that a freeze plug? im pretty sure thats not where the water was coming from. it may be somewhere slightly lower than that.

 

[warrior24]

yes thats the freeze plug

the head may be cracked

 

[UrbanRedneckKid]

Clean the back of that beast with some brake clean, get a mirror, a flash light, and find out exactly where it's coming from.

From what you've told us, it could be,
Freeze plug
Cracked head
Blown head gasket
Lower intake gasket

Good luck, hopefully it's the intake gasket...

 

[koa's93ranger]

ok i just checked it out today. finally made it home from work in time to still have sunlight

its coming from the lower intake manifold gasket. directly in the center of the engine, just as someone stated earlier.
and there isnt coolant coming from anywhere else. (heads, head gasket, freeze plug)

so just pull the top half off and replace the gasket and bada bing, done! ...right?

 

[koa's93ranger]

ok. got my truck fixed. luckily it was only a blown lower intake gasket. thank god it wasnt anything worse.

thanks alot for all the advice guys

Hey Kylan, what is the thing plugged in just above the flywheel in the center?

 

[SoLongStang9499]

cam position sensor

 

[Kylan]

yep cmp, only on california emissions models

Nope. I have a 95 OHV and that sensor is there. they moved it off the crank pulley to the cam. The 95 I have was also equipped with EGR.
