Hi everyone, the problem that I have is I am leaking radiator fluid from the backside of the engine, can't quite put a finger on the exact spot tough to see. I am going to guess that it is the head gaskets. Some questions that I have though are that there is no over heating and radiator fluid has not mixed with the oil YET. I also noticed tiny air bubbles coming from the spark plug closest to the driver. Wouldn't a blown head gasket be losing compression and actually making a hissing sound.???

Thanks , midessa7

Yep, that is leaking head gaskets. Time for an overhaul.

 

Could also be the intake gasket. Thats a common spot for them to leak.

What do you mean by tiny air bubbles by the spark plug? Is it leaking into the spark plug well?

 

Will you be doing the head gaskets or a shop?

 

I think I'm having the same problem, noticed lately ive been running a little low in the coolant reservoir...looked under her and noticed that there is a leak under there, but not exactly sure where its at, it is dripping down on the front axle, dead center...if it is my heads, how much am i looking at to fix? shop or diy job?

 

Fill your coolant bottle full, to the lid, every morning before heading out and Have some one check this ASAP.

 

I fill it everyday. I will not be doing the work, I'm getting a few quotes. As for the bubbles it's just like I said, I saw a few tiny bubbles coming from the last spark plug closest to to driver while the truck was running, strange I know. I love the truck so I will be getting the work done. I'll let you know how it turns out.

Thanks, midessa7

 

Head gasket it them because of the bubbles.
$1400 to $1600 plus head work if needed. Make sure to change your plug wires, 8 mm Magnacor's, update your upper radiator hoe to the newer design with the bleed screw in the black plastic tee and install a new t/stat.
