SOURCE: 1998 monte carlo coolant
I just did a lower intake reseal on my 98 monte's 3100, it's not tough to do, the biggest part is paying attention to what pushrod came from what position and ensuring they go back to where they came from, not only for wear patterns, but for different lengths on the intake and exhaust push-rods.
I work for a GM dealer in northwest montana, and I can say it's not cheap labor-wise, generally around 6 hours of labor and around 300 in parts...it can add up quick, but when those intakes start leaking oil and coolant, things can go sour quickly...espeically if coolant starts leaking into the engine, not good for bearings.
Dex cool is not the problem with these gaskets leaking, it's common on 3100's, 3400's, 3300's, etc, any motor from that series that has that style of lower intake is prone to the issue, the rubber/plastic/composite will eventually warp, break down, crack, seperate from hot and cold cycles, I've seen it all too many times. Dex cool is the best coolant out there, there's a reason that prestone, peak, zerex can't compete, in fact a few of those blends are blends that are less efficient that Dex that GM decided not to patent. But the Dex patent is due to run out soon to the point everyone can start using dex. One issue with dex is the "gum-up" problem when the mixture is not ideal and the level is left low, but flushing and setting proper mixture (50/50) and level will alleviate this problem.

I personaly dont see many water pump gaskets leak, but instead there is a weep hole that they leak from when they wear out. they are designed this way. which is common. reason it may leak with ignition off is now the pressure builds up verses being cycled through the engine and doesnt reall have time to squirt out.and it just finds a way out with engine off which would be your weep hole most likely.
Its not hard to fix or replace water pumps on the gas engines. there should be the large A/C and powersteering bracket that can be removed and sometimes if you dont have clearence the alternater bracket. its not very hard. basic tools work just fine. the only thing that may be alittle hard is the fan nut. you will need a large wrench and something to stop the pully from spining while loosening and tightening that nut. should take about 2 hours or so. IIRC13mmm, 15mm bolts, 9/16 bolts and 10mm and 8mm bolts. that all you need.other than the large wrench. pipe wrench will work but you need something to prevent the pulley from movning. thats very important.
Good luck. I hope i answered your question.

it is likely a small leak i'd get a plumber money well spent you don't need the expense of a flood or search with a very brite flash light.Tom

i have a 1999 ford explorer v8 5.0 and it is leaking right behind the waterpump. but not from the pump, about 5 inches behind the pump, like by the block, what is it?

It is your Lower Imtake Manifold gasket (LIM). Late Production Camaros and Firebirds used Dex-Cool coolant which nortoriously caused the LMI to actually disintegrate. The failure of the LIM allows coolant to leak to the exterior of the engine as well as into the interior of the engine eventually getting into your oil. Check your oil for a brown milky color... if you have it immediately drive your car to you favorite repair shop and replace the LIM gasket. The GM 3.1L, 3.4L and 3.8L engines are famous for disintegrated LIM gaskets and a good shop will have replaced 30-50 of these in a year. The LMI is part of the reason the public dissed Pontiac and eventually led to its demise (not to mention bad management at GM). Find a shop familiar with the LIM problem and it shouldn't cost more than $500 to replace (or less). If you have any mechanical skill you can replace it yourself... the gasket kit costs about $35 at NAPA AutoParts and it takes a whole Saturday if it's your first time. I just finished replacing the LMI on my wife's '94 Firebird.
