Not hard at all first remove all the hoses and clamps
than undue all the bolts that hold down the intake manifold should go around in a pattern of some sort all the bolts should be identical and that's it. You may have to pry it off a bit with a screw driver or tap it LIGHTLY with a rubber mallet to break it loose and that's it.

than just clean both mating surfaces with a razor get all the gasket material off and sand it a bit with some rough sand paper than you can slap it together and that's it your done done forget to use silicon around the water areas highly recomended to avoid water leaks or over heating

You unbolt the intake manifold, remove the old gasket, install a new gasket, and bolt the maniforld back on.

You may have to remove sensors or hoses that block removal of the intake manifold.

you'll need a torque wrench when you bolt the manifold back on

What is the book labor to change a head gasket on a 2002 1500 Suburban

Can't say for sure but its not cheap .
Thats not why I answered you .The problem may be the head gaskets but most likely its not .
The intake manifold gasket would be far more likely to be the problem with a Chevy engine and its a lot cheaper to do . Check it before you commit same symtems has it over heater lately that will do it everytime

Very poor idle 1990 k1500 5.7

First things to check are vacuum lines and hoses for cracks or unhooked. Check iac valve on throttle body for dirt or block passage and gasket between throttle body and intake manifold for leak.These are easy to do and low cost.

94 GMC Suburban. Replaced intake manifold, now runs poorly.

You may not have sealed the manifold correctly,mistakes like using the rear and front rubber seals can cause this instead of a bead of silicone. To check for intake leaks spray carb spray along the intake gasket to see if the engine changes tone or idle speeds, if it does you have a leak,.

easy. you have a vacuum leak at the intake manifold. spray some lubricant along the gasket at 5 & 7. should stop missing if leak is on the outside. but if on inside it wouldn't make a difference. I vote to change the intake gasket. I'm having to do the same with a astro van.

Replacing a 99 chevy intake manifold/head gasket

These engines are legendary for intake manifold gaskets leaking, and this is exactly what's happening with this one. Yes, you will have to remove the intake manifold, and to do so, you will need the torque diagram to remove it, and also to torque the new one. It's best that you buy a Haynes manual so you know the exact procedure; it's a $15 insurance that you will be glad to have. If you aren't having problems with the head gaskets, I'd leave them alone personally, but if you want to undertake these, now would be the time to do so, as there's not a lot more to take apart. Main suggestion though, is to be absolutely sure you keep the push rods in the exact order and orientation, as they each have a unique wear pattern with the lifter. Changing them can cause them to lose their seal, depriving the valve of oil, and ruining your head.

1999 suburban usung a lot of antifreeze

Some of the V-8 engines like to leak out the back of the intake manifold. It then drips onto the exhaust and evaporates so you never see it, you just smell it. Look for it back there. You may want to have the system pressure checked too. If it is leaking out the intake, it is not an easy or cheap fix. I just did my 96 Yukon and it was not fun.
Good Luck and hope this helps.
