Sorry wasnt sure where to post this but;
Car is a 1996 ek, was changing the coolant in my radiator and decided to clean my iacv as well, so i cleaned the iacv, topped up with cooolant but noticed it was taking alot more coolant than it shouldve, which is when i noticed the coolant leak, it was coming out of the intake, so i took out the intake, throttle body, and peeked inside to see the whole intake manifold filled with coolant, must have had a leak through the iacv?
the car hasnt been started yet, is there a way to drain the intake without removing the whole thing along with all the hoses connected to it? Can i just loosen the bolts that connect the manifold to the engine and let it drain like that? Is my car screwed?
Thanks

You can just burn the coolant out by runing the car not sure if thats exactly safe.. or you can force air into the manifold(taking 2 hoses off, and blowing air into 1) or sucking the coolant out from only 1 hose.. how much coolant is in the manifold? A cup full? Half a cup?

remove spark plugs
unplug injectors
crank engine until water quits spraying out
change oil
reinstall spark plugs
reconnect injectors
start engine

Agreed.

Don't hyrdo-lock your motor by trying to start it.

Also, replace your intake manifold gasket. It could be leaking from where the intake mounts to the head.

If coolant gets into the combustion chamber, itll burn, simulating a blown headgasket until all the coolant is burnt. Hydro locking would occur if it was purely water since water cant be compressed.. Coolant can.

Either the intake manifold gasket is leaking or the fitv is leaking internally.

It cant be the iacv leaking since the coolant path for the iacv is sealed off.

IS there an FITV on the 96+ D16? I didn't think there was, only the IACV.

thank you all for your quick reponses, here is a pic, quite alot

thats what i thought as well, but as i was pouring coolant in it it was coming out of the intake? what if the iacv gasket wasnt fitted correctly when i was cleaning it?

i havent started the car in like a month and there was no probs or signs of any leakage, just now when i poured coolant in with the car off

Oxadiba

im actually starting to think its the intake manifold gasket now since ive been having idle problems even after cleaning the iacv a month or so ago so will probably replace it

theYBLEGAL

Ya. Thinking about it more, if you have not started it, then gravity won't allow the coolant to any location higher than your filler cap. So, anything above the head is probably a no.

Ferio- never know if a guy has 50/50 coolant mix. Some have more water. Not good to chance. + a hg leak is not a full cylinder of liquid, generally.

Looking at the diagram its actually possible either the throttle body has a crack or maybe even the gasket is bad.

Really? Dude shut up and stop giving out HORRIBLE advice.

Coolant is no less likely to destroy your motor due to hydrolock than water. A SMALL amount of coolant from a MILD HG leak would probably burn off. Any substatial amount of fluid is going to hydrolock it.

No FITV after 95.

Caoboy

I thought so...

Oxadiba

Any other advice to get the coolant out? If i were to just take the manifold off theres a good chance alot of coolant is gonna get into the engine which i would like to avoid

holmesnmanny

Just use a turkey baster.

Oxadiba

Would be pretty difficult since the manifold is pretty deep, need something longer and more flexible, ideas anyone?

cafrog

A cheap Harbor Freight manual pump might work.

Turkey baster with a Jack in the Box straw? Those straws are kinda big in diameter and could be connected to the baster. What a hassle though.

TomCat39

I don't follow your reasoning on this.

If you have coolant pooling in the runners, it's already sitting on top of the backs of the intake valves and the one valve set open it's already in the cylinder.

Taking off the intake manifold will let all the coolant drain out of the runners and head.

You still will need to shop vac the intake chambers to get the pooled coolant off the backside of the valves.

As well as having to get the coolant out of whichever cylinder the valves were cracked open on.

ferio-ichi3

**** off, we didnt know how much coolant was in the manifold until now. You just said the same thing i said, what about my advice was horible?

holmesnmanny

Because you said coolant can be compressed. You can't compress liquid.

this thread has been compressed

Soo when you have a headgasket thats blown, and you are losing coolant, whats happening, that coolant is just going nowhere then?
