Coolant problem update w/pics

3795 Views 51 Replies 14 Participants Last post by  slikirish
Ok so went out and looked at the car this morning and didn't find any coolant on the ground. Popped the hood and this is what I found.

Oil doesn't seem milky but the coolant overflow is empty again. So it would seem to be losing the coolant before it gets to the engine. I'm not going to run the engine anymore until I get this figured out.

You guys have any idea where this is coming from? There is orange "powder" all the way down one side of the heads, other side is clean. Any ideas?

Holy crap. I didn't think it looked that involved. I thought it was another O-ring. I may be picking up a Haynes manual tomorrow at advance as well.
Its not really that involved. 90% of the job is just remove misc bs in order to remove the intake manifold. Once all the bs is removed and out of the way the gaskets can be changed in less than 5-10 min.
while your in there might as well go ahead and change out that cracking belt:2cents
Came here to say this...
Looks like the intake manifold gasket. Reason I say that is you have the intake mainfold with aluminum crossover -- known to have a less chance of cracking etc, if it was the thermostat gasket it would be leaking from farther up top/around where the thermostat housing and intake manifold come together. You can pick up a set of gaskets for $35 bucks or so and swap them out in less than an hour if you have a general idea of what youre doing....This is based off of your second picture. I couldnt see a whole lot from the first other than where the coolant has leaked.
What else should I replace while I'm at it as far as general maintenece goes?
How many miles are on the car, original owner (or know when everything was changed last) or used and you just recently got it?
Just got it 5 or 6 weeks ago. 76,000 miles.
Id do some ngk plugs (good and cheap), fuel filter (10-14 bucks for an oem at parts store), flush coolant (looks awful from pics), belt (looks bad from pics), check brakes, add some stuff in the fuel such as lucas and call it good.
I assumed I would get to the plugs. Is the fuel filter up by the motor as well? I'm just looking for things I'm going to be getting to b/c of taking the intake manifold off. Belt and coolant flush are already planned.
Fuel filter is in the rear. Kinda hard to explain where you can find guides online that point it out directly. Easy to get to though.
Ok so as far as this specific job goes I'm looking at doing thermostat and thermostat o-ring, serpentine belt, intake manifold gasket, plugs, and coolant flush.
Sounds good. Fuel filter would be good too.
The fuel filter is located above the rear axle tucked up next to your gas tank. Its should be silver and the size of a small drinking glass is the best way I can put it. It will also have a clamp holding it. You will also need a 5/16" fuel line disconnect tool to get the lines out of the old filter. The line will simply snap into the new filter. Good luck!

Found this also for removing the intake and tq of the intake, there a few steps you will not do like removing the water pump. This is a write up about upgrading from a NPI to a PI intake.
I'll report back after she's done. Seems to be pretty much a full tune up getting down. Hopefully I can get it done in one day.
intake mani leaking.
What is optimal spark plug gap for these motors?
my intake cracked where the cast coolant crossover tube sandwiches the intake between it and the head. the thermostat housing bolts go thru the housing, thru the crossover tube, thru the plastic intake then into the head. just saying to be prepared to replace the intake. dont drive to long like this, coolant ran down the back of my motor and caused the throwout bearing to go out.
I'm not driving it all until it's fixed. Got started on it today but not finished. More work on it tomorrow.

i dont blame him...that thing is cracked pretty dang bad and wouldn't be surprising if it were to break...needless to say, that would suck
Got down to removing the intake manifold and it actually is cracked. It's not just the gasket. I had thought that they stopped using plastic in these manifolds b/c of this problem. Does this mean I have an older style intake manifold or is it that they still use some plastic in production of the manifolds?
