M130 engine manifold removal

i am trying to remove the manifold, change the gasket.
first,
when i removed the last two bolts closer to the firewall coolant started to come out, is this normal?

second i can't get the manifold out,
i can slide it to the left and the last 1cm before it comes out of the bolts i can't.
the exhaust pipes are stopping me for sliding any more and i tried to move them aside with no luck.

i don't know if the base for the carbs comes out but one side is stuck at the gasket area and can't remove it.

is there any trick to this as i am stuck for now.
Thank you

No
Where are they located?
How far from the engine bay

And should the exhaust ends go up or down when removing the manifold?

There is a metal bracket/clamp at the trans mount, and then at the back of car before and after the exhaust muffler are rubber donuts. I think I just undid the one at the trans completely.

???
once the exhaust is out of the way, you can just pull the manifold straight out.

you are suppose to replace the manifold nuts with the nice copper ones you can get at autoAZ, though i did reuse mine. dont use steel ones.

try mag wheel cleaner on the manifolds to clean them up!

Ok
I removed the head and the manifold came out
When I go back to install everything back I will loosen the exhaust
It only needs very little to move but since it I'd bolted is a no go

My manifold bolts are not steel so someone replace them I guess.

How about the fact that coolant was leaking when I removed the back two bolts, is that normal?

Thank you

Yes, and depending on which M130 you have, removing other bolts may result in oil escaping/leaking. The AC belt tensioner mounting bolt comes to mind.

Get new "sealing rings" for your manifold to downpipe joints too. And use copper based anti-sieze on the exhaust bolts when reassembling.

You mean seals for where the exhaust starts?
Yes some metallic rings came off , I think you are refereeing to those
Thank you
