theres an easier way to fix a blown gasket, its called seal-up you pour it in your radiator and it chemically welds it back together look it up on google most auto shops sell it or something similar, but replaceing the gasket is the best way

SOURCE: replacing the intake manifold gaskets and head

Before accepting any advice on the torque specifications for the bolts, you should refer to the Haynes manual that specifically relates to your vehicle. The reason reason why knowing the torque specs. for these various bolts is not good enough is that each bolt will need to be tightened in a certain order/sequence. The Haynes manual provide you this information and a lot more! These manuals will run you about $10-$15 and they can be purchased at most auto parts stores (i.e. Auto Zone, Pep Boys, etc.). Good Luck!

SOURCE: Over heating 2002 Aztek First mechanic we took it

If the water pump and thermostat have been replaced and the system has been properly refilled and bled , the only thing left is the radiator. If coolant is not flowing through it properly , vehicle will run hot. If your car has overheated to the point of boiling over , your new thermostat may now be damaged again.. As for the fans , they only come on when the coolant reaches a certain temprature. Under normal driving conditions , they would not need to come on while the vehicle is moving , as the air flow from driving down the road would be enough to cool the engine.

How to replace head gaskets

What engine? Has thermostat been changed? You say it has not overheated since, but water not circulating. If water/coolant wasn't circulating, it would be overheating. Please explain a little more or confirm why you think that.

Got coolant in oil, so it's head gaskets or i was told its an air intake valve that goes through the throttle-body or a crack in the block.

It`s either going to be a head gasket, intake gasket, or cracked head or block. I wouldn`t expect the head or block to be cracked unless it has frozen or been severely over heated. It`s more than likely a head gasket.

My 97 intrepid is idle to hight

I'm guessing this Intrepid is a 3.5 cause I have never had this problem with a 3.3 But what I found what always caused it in a 3.5 is bad intake gaskets allowing more air to flow into the engine. Change both upper and lower intake gaskets and this should fix the problem. However when changing the lower intake gaskets there are two bolts that are probably gonna give you problems. The one closest to the front and the one closest to the back. They are the bolts that hold the intake down and go into the head near the coolant ports. These bolts are probably going to break off. The good news is they most of the time break off and there is still a lot of bolt left once you get the intake off to get a vice grips on. Have a torch with a good heating tip handy and someone that really knows how to use it and heat the cyl head around the bolt and then try to get it out with the vice grips, but be very careful cause heating aluminium can be very tricky too much heat and you ruined the head.

My 1997 Taurus will not hold water and is leaking out under the intake manifold. I have to keep adding water... How can I fix it?

Is there water in the engine oil? You may have just blown the intake gasket but it may also have warped the head(s). If you are a good do-it yourself-er you may be ok with the repair, but it is not easy to replace. If you question your abilities take it to a reputable shop.

I just changed the thermostat on 3.4 L 1999 Pontiac Gr Am GT THINKING IT WOULD FIX THE OVER HEATING. But there is white steam coming out the exhaust! The oil is not milky so it's not a head gasket. There's...

Are you adding coolant?
Yes ......means it's going somewhere.
Fill the coolant tank to the top...right to the top....leave the cap off and run the engine.
If you see bubbles you need a head gasket.
The intake gasket is another source of coolant leaks and at this area the coolant can be sucked into the engine and produce a white smoke.
Does the car run rough at the first start in the morning....could be antifreeze burning off in the cylinder or area that was leaking overnight meaning cyl gasket or intake gasket.
Look at the rear head to block area below the exhaust manifold.
Is there any trace of coolant or stains of coolant......yes means head gasket time.
Pressurizing each cyl at a time with air with the valves closed in that cyl will quickly show the location of the bad head gasket with bubbles coming out of the fill tank on the bad cyl (s).
Head gasket leaks don't always mean milky oil.

I had new intake manifold gadket installed noe

Since problem developed after head gasket replaced. I would look at head gasket. Try re-torque head bolts. Was correct gasket size installed? (due to wear and tear, sometimes OEM gasket is no longer correct).
