Turn signal switch. With you foot on the brake have someone stand behind the car. Wiggle the turn signal lever and see if the the brake lights flicker.

How do i jump start my monte carlo? the battery is located under the windshield wiper cover
Ground connects LAST. Look around there is a positive attachment somewhere, usually under a red plactic cover, that is the positive hook up, negative to some major metal somewhere on the engine...
No smoking during this event, explosion hazard.

head gasket or timing cover coolant leak. front of my 3.1 leeaking coolant by the altinator
i'm guessing that your car has approx 130k or more miles on it. these engines are cousin of the old 2.8L V-6, and have a tendency that if you don't constantly monitor you coolant level, or the engine is abused, (hot rodded), that it will crack a block, take it from me, after approx 130k i got a cracked outer water jacket, but it ran perfectly fine and i drove it for another 20k, but got tired of having to add water to the radiator everyday, so i purchased a new engine, put another 150k on it, and now have a blown head gasket..i'm not one to try any type of block sealers as most of them contain solids, (sodium silcates or liquid glass), and it"ll clog up your radiator, and possibly your hearter core,..but my car has 297000miles on it, so what the heck, what do i got to lose..so i purchased a bottle of "Blue Devil" $65 ( supposedly doesnt contain any solids), at Kragen autostore, they didnt stock it on the shelf, they had to go into the back room to find it. Well they told me that you have to follow instructions to the letter, and i thought how hard can it be, but you are supposed to shake it before pouring it in which i had over looked and when i took out the thermostat, i didnt have the rubber seal in properly and lost most of this when i saw it leaking out onto the ground, so i shut it off and just reinstalled the stat real quick and started it back up...i let it idle the full 50 minutes like it said and the vapor stopped coming out and the low coolant light stopped coming on..but when it came time to test drive it i only got 10 miles before the low coolant light came on...so i kept losing about a half pint of coolant and had a slight misfire until the plug burnt of the water. So i still had half a bottle left, and did it again, this time with the heater on full blast like the instructions say to do.. and now im not topping off the radiator anymore and the engine oil is finally starting to go down...now i just got to change the oil out before i spin a bearing...because water isn't a good lubricant!
Check your oil cap or dip stick, if it doesnt look milkly, then you probably only have an external leak. the verdict on Blue Devil is still out, only 150 miles so far without having to add water! and i totally screwed up and didnt follow instuctions. i myself wanted to purchae another "crate" engine like i did back in 97 but they dont stock the 2.8L anymore. if you are going to spend big bucks to get this problem repaired and its a high mileage vehilce, i would ask if they carry replacement engines, not a rebuilt, but a brand new long block crate engine...back in 97 it cost me $1500 for the engine and $800 labor. ran good as new! and i squeezed another 13 years out of it...it sure beats new car payments. be careful of shady mechs when you go into repair timming cover coolant leaks because i pulled a little tab off the gasket so i would have proof that they did the work and not try and pour in any type of block sealer and the guy got real upset when i did that, well i didnt want him working on the car so i just took it to a dealer.

My 1998 Monte Carlo (Z34) has recently started stalling when I come to a stop. After a short search, I found and repaired a broken vacuum-hose from a connection to a large empty plastic-ball that I found below my battery. I also found a small crack on a rubber fitting going into my fuel-pressure regulator ( which a temp-repaired ) and a large crack on another rubber fitting going from my fuel-press reg. and some evaporator soloniod ( which i also temp repaired ) into my throttle-body. I even cleaned out the throttle-body, by spraying carb-cleaner in as I revved the engine. Now it does not stall as often, it even runs smoother, but the RPMs will accasionally jump up and then drop to below 500 ( randomly ) causing my car to stall. What can I do to keep my RPMs stable?
ON THE SIDE OF THROTTLE BODY IS THE IDLE AIR CONTROL MOTOR GENERALLY HELD IN PLACE WITH TWO TORK SCREWS REMOVE SCREWS AND SLIDE OUT OF THROTTLE BODY THERE IS A PLUNGER ON END OF IAC MOTOR CLEAN IT GOOD AND THE SEAT UP IN THE THROTTLE BODY AND RE-INSTALL THIS MAY HELP TO ALLEVIATE SOME OF THE FLUCUATION IN RPM,S CLEANING CAN BE DONE WITH CARB SPRAY AND A OLD TOOTHBRUSH

I have not had this car overheat to my knowledge. orginally i thought the water pump was bad. it started to leak one day from what apeared to be the water pump. i changed the water pump( more than once),and the leak is still there. i have been under and above this motor. it appears to be leaking just behind the power steering pump to the left of the water pump. i have tried to locate the leak to no avail. it leaks while the vehicle is running and while it is off. also have ran it while it has been leaking but does not overheat. i dont know but do not believe it to be freeze plug. i have researched on the web but no definitive clear answer.
Thanks
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.

My 98 Monte Carlo won't start. The lights, radio, windows all work, but when I turn the key nothing happens.
check the fuses there is a starter fuse, if not check the starter for power at the small wire if no power could be the relay,if you have power at the small wire its the starter that's bad.

Car has been shaking a bit when i first turn it on and when I let it idle. No issues when I'm going down the road. Now I am getting P0171 System too Lean (Bank 1). Inspection coming up soon and I need it to pass emissions test. My mechanic just passed away right before this code came up and I haven't found a new one yet, any help would be appreciated.
Replace the upstream oxygen sensor or two, if that
is what you have.
The ones closest to the motor
That should have been done at 100,000 miles
You don't need a mechanic to unscew an O2 Sensor
