Question about 2002 Pontiac Bonneville

Open Question

What is the process replace a radiator in a 2000 Bonneville SLEl

I have been smelling antifreeze and noticed a crack in my radiator. My radiator is a dual coil compared to many singles and seems to be much harder to remove with many more connections than many of the videos and DIY information sheets. If anyone has replaced a Bonneville radiator, knows the process, or could tell me how long it may take to do it myself I would appreciate it.

You know where you insert the Gas Nozzle to Fill it up? That is the Filler Neck and it can Develop Holes that will release Gas Fumes.

SOURCE: Changing the starter solenoid on a 2000 Pontiac Montana

On your van the solenoid is attached to the starter. If you can get a solenoid separate (i don't know if you can) then you will need to take the starter off and remove the solenoid (2 screws holding it on) and the wires (on red and one black i believe) pay attention to which wire goes where because you don't want to reverse it on the new solenoid.

SOURCE: how to remove radiator on 1992 pontiac bonneville

Removal & Installation

  1. Disconnect the negative battery cable.
  2. Drain the engine coolant into a suitable container.
  3. If necessary for access, remove the air cleaner, mounting stud and duct.
  4. Remove the upper fan mounting bolts.

On some vehicles, such as this 1998 model, remove the upper fan mounting bolts
  1. Unfasten the retainers, then remove the upper radiator panel.

CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old. To avoid being burned, do NOT remove the thermostat housing cap while the engine is at normal operating temperature. The cooling system will release scalding fluid and steam under pressure if the cap is removed while the engine is still hot.


  1. Remove the cooling fans, as outlined later in this section.
  2. Disconnect the coolant reservoir hose from the radiator neck and the radiator hoses from the radiator.

  1. If equipped, disconnect the engine oil cooler lines from the radiator.
  2. If equipped with an automatic transaxle, disconnect the transaxle cooler lines from the radiator side tank.

Antifreeze smell and loose antifreeze in the engine compartment, 2001 Nissan Altima.


Radiators with plastic tanks suffer from splitting/cracked tanks on the older cars. Any coolant outside the radiator is an indication of failure and the radiator should be replaced with a new unit as repair costs almost as much as a new one. There is no need for genuine as the radiator manufacturers make genuine and non genuine to the same specs for around half the price. Any accredited radiator shop will have a unit for you.

Water not staying in radiator no sign of leaks in my 2000 bmw


does the car seem to run roughly? sounds like a possible head gasket or a cracked cylinder. is there an unusual amount of moisture coming out of the exhaust pipe, would smell like antifreeze gaseous sweet smell. a crack will fill either the top of a given cylinder but only when the engine is not running. head gasket will dump water into the oil giving it a milky look also will be prone to overheating

Smoking with sweet smell


White smoke sweet smell. Sounds like Antifreeze evaporating..check your radiator and hoses, as well as your heater core. It is hard to fully answer a question without a hands on inspection, kind of like me asking you over the phone if you like my new tie I am wearing..

Sugary burning smell while driving


That smell is most likely antifreeze. If the smell gets noticeably stronger when you turn on the AC/Heater, it is possible that your "heater coil" has started leaking. You will need the services of a professional if that is the case. Those are very hard to change.

Another possibility is your thermostat is not opening, causing your engine to overheat - steaming some of the coolant (antifreeze)/water mixture out of the system.

And thirdly, it is possible that someone spilled antifreeze on the radiator etc when adding fresh antifreeze - and you smell it after the engine warms up. If your car is not over-heating and you are not having to ad antifreeze/water to the radiator, then just keep driving. The problem will most likely go away.

I hope this is helpful to you. If yes, please take a sec to rate me. Thanks!

The car was bone dry on antifreeze. while driving yesterday could smell antifreeze and i have no heat


prob heater core, roughly 750 to replace, whole dash needs ripped out..unless it is just a hose off at the firewall leading to the heater core or leaking radiator hose..fill the system with clean water and look for leaks, you wont have heat without enough collant in the engine to circulate under 13 psi closed system, check the resevoir for cracks and leaks mine fell apart over years good luck

While in my way home, I noticed sudden rise of engine temperature. The radiator water is empty.I noticed that the engine radiator has cracks arount the clipping metal. I brought my car to the nearest...


It is normal for some antifreeze move into the overflow tank when the engine cools down after it is shutoff and draw the antifreeze back into the engine when it is warmup, but if it is push antifreeze into the overflow tank and overflowing the tank then most likely the cylinder head is cracked or the headgasket is blown. You can take it to a automotive shop and have them check for hydrocarbons (exhaust gases) in the radiator.

Good luck

Replaced cracked radiator in 2000 Chrysler LHS but car still overheating. What could be the problem?


fix the radiator first.because coolant temperature sensor need to be in antifreeze.when antifreeze get up to 190 degrees. the coolant sensor act as a thermostat.it resistance decrease then the pcm will command cooling fans to run.if antifreeze low the coolant temperature sensor not going to work. engine is going to over heat.
