Default Any online help with intake gasket repl? Add'l pointers?

Looking into intake gaskets on my 93 SE (w/ 150K). Have been seeping out for some time (mech friend said a while back), now I am noticing more coolant loss. None in oil, and no smoke, so don't think it is burning. I'm not sure if this project is more than I can handle; I've done a lot of the repairs on my car myself (brakes, ps pump, master cylinder, sway bar links, heater cores). Seeing you guys are extremely familiar with intake gaskets.....

Are there any sort of how-to guides on here (or the internet) for this project?
Any special tools that I would need? (aside from torque wrench)
Anything else I should replace while I am in there?
Do the '93'* like mine have all the manifold problems like the '95'* do? Any chance my manifold is shot?

I figured I'd need the upper and lower intake gaskets, along with replacing the thermostat and radiator cap (both have never been replaced in the 6 years I've own the car, and those parts are cheap.) Any other parts? Brand recommendations?

I was also hoping to get by without buying a Chilton'* - if I can !

Thanks for all info!! ~Jon

Well if you're going to replace the upper intake gasket, you should think about replacing the UIM itself too.

I just helped do this on my car, and it was pretty worn down for being only 4 years old.

We also replaced the coolant elbow, which was about to go. They are only 3-4 dollars.

Go here for more info

(edit: I just saw yours is a 93, I don't know about the UIM for that year and the link above is for 95-03 I think. So somebody else who knows more will chime in)

I went to the library, and they had a chiltons van service manual, which included the Lumina van with the 3800 motor. From the pictures it seems like the exact same motor, and being the same year, it should be, right? I didn't check it out, cause I forgot my card, but the instructions and torque specs should work for me and the Bonne, right?
