Today got stuck in the snow and had to rev a little hard.next thing i know steam is poring through the vents and coolant on the pass floor ,but there is coolant all over the top of motor also mostly on the manifold.could i have blown both?or might it just be the manifold?thoughts please.

UM yeah, that sounds like the heater core, but if there is fluid on the manifold you may want to check the hoses especially the one coming off the heater core.

well i found alot of coolant in the V area under the plastic manifold.do hoses run through there?

 

[coralguy99]

Well it looks like the plastic manifold is possible cracked i can see coolent dripping behind the alt and it may have just been water on the pass side from snow feet
But would this still cause steam to blow through the vents?

I would guess that your heater core is okay, that the coolant and steam you have inside was drawn in from the outside, and not from inside the heater case.

Doesn't mean the heater core didn't go, it could have, but I wouldn't wish changing that out on anyone. I would do 10 intake manifolds over 1 heater core.

yup,your guess seems to be right (steam being sucked in)the intake cracked at the first runner just behind the alt.after the first blow i could not get it to blow from the vents again.
I was really hoping it was not the heater core.and seems it is fine.But that first blast of steam was pretty freaky
Any one in MI wants a mechanics special pm me.

is this the right manifold for direct bolt on and is there anything else needed Gaskets ect.

Yes that is the correct manifold for your motor. I imagine it would be best to replace your intake gaskets as well as the thermostat and t-stat housing gasket while you're at it.

Mine did that! It had a pinhole rubbed in the hose. It was against the a.i.r. injection tube on the back of my old 5.0- It didn't leak unless revving the engine or pressuring it up with a tester.

Somehow coolant got inside the car and I smelled antifreeze. I was so happy the next day when I found out it didn't need a heater core.

B.T.W. where can you buy a heater core for a tbird that isn't copper When mine gets replaced I want it to last another 15 - 20 yrs
