98 buick lesabre starting problems and coolant leak

I have 98 buick lesabre that just starting having some problems starting. When I turn the key, I hear a click, but the engine will not turn. After a few minutes of trying it starts. I took this to a mechanic who said it was due to a gasket leak (intake manifold, coolant leak) which is causing a problem with the pressure. He also said that unless the gasket and pump are replaced, this problem will deteriorate to the point where the car will not start at all.

The estimated repair is $1500. I have haven't seen any posts on a coolant leak resulting in car not being able to start before. Is this correct, and if so is the estimate I was given a fair one? Also, does this need to be done immediately or can this be delayed - I really don't have this kind of money to put into a 10 year old car. Any feedback on this is appreciated.

    I'm having the exact same problem. Don't know if this is related. But, I first starting having problems Mass Airflow sensor. I cleaned it and the problems went away. Later on I notice there was coolant leaks and the engine light kept coming on. I just put extra coolant into it. Now, after about 1 month I my car is not starting. I need to take the car into ths shop tomorrow. I have a 97 Buick Lesabre.

That is a common problem with upper intake ..when starts going bad usually you will have excessive white smoke out exaust pipe or check oil on the dipstick for milky color oil . if it gos bad it will cause the motor to hydro lock. thats when antifreeze gos into the clyinder causing the motor to lock up.. and as cost most places charge $1100 to $1500 for that repair..most of the time you wont see a leak because it leaks inside the motor. hope this helps

I had the same problem and found this article
"The issue is the intake manifold gasket in some GM vehicles. According to CTV, the part may degrade in vehiclesbuilt between 1995 and 2003. In worst-case scenarios, the gasket is failing, introducing coolant to engine oil,rendering the latter ineffective and resulting in siezed engines."

    My car ran rough all the sudden. I checked the oil but no water but the radiator was low. I checked the dipstick and no water in the oil. I refilled the radiator and started it up. It ran for about 60 sec and then sputtered and died. Then it wouldn't sart. The engine seized because water and oil leaked in the intake manifold and filled the piston chamber preventing the pistons from moving. Some times this can be just one or two pistons. So, remove the spark plugs and look for oily/wet plugs. I pulled one plug off and water/oil started streaming out. Once you get the plugs off, you can try to start the car and see if the engine turns over. Mine did and it spewed water/oil like a 1 yr old projectile vomits milk! So don't leave your head under the hood when you crank it. If all the plugs are out and it turns over you may be able to replace the gasket ($50-100) and get it working again. If you hear grinding or noise other parts could have broken inside and might not be worth the fix.

I have a 98 buick lesabre. I am a woman and have no clue whats wrong with it and cannot get straight to the point answers of what is wrong with it. When i drive it, it gets hot, my windshield fogs up,...


your heater core is leaking. It is allowing engine coolant to enter the passenger compartment via the air conditioner / heater ductwork. A cheap temporary fix is to purchase a radiator stop leak product and have someone put it in your radiator. Follow directions carefully, as the coolant can be very, very hot and under pressure. The correct repair can be quite expensive. In warmer climates you can bypass the heater core and run without a heater.

I have a 1998 Buick Lesabre that keeps losing antifreeze.


Buick 3.8's are notorious for intake manifold leaks. If you are sure you are not leaking externally (look under the alternator and on the top of the transmission), it could be an intake manifold leak. I've replaced mine...I didn't think it was too hard a job for an amateur.
It could also be a head gasket, but the intake leaks are much more common.

98 lesabre grinding starter


most likely your bendex wheel in the starter is not engaging the flywheel this could be due to a bad solenoid on the starter. chances are it's a bad starter, i would check to make sure all connections to starter are tight and you have atleast 11.5 -12.5 volts of current in the battery. low voltage can cause this problem as well
