Question about 2000 Pontiac Bonneville

Possible heater core issue

I first thought I was just low on anti-freeze due to the fact that the heat would get cooler once in awhile but a couple times I seen some steam coming out of the drivers side hood or wheel well but when I wold pull into a lot to check it out-- nothing-- but I could smell some anti-freeze and the carpet is somewhat wet but it is winter and we have had alot of snow, but I have also added more fluid due to gettting cool once in awhile again. How hard is it to replace if it is the heater core.

Removal of the dash and unpluging all of your wiring.It is a 6-7hr job when you have all the tools but you will need short and long extensions standerd and metric sockets.

I would say it is on a scale of 1-10, 10 being hardest it is like a 4 or 5.
You can do it yourself all it takes is looking to see how things a bolted in. Just w/e you do do not unclip any orange wire connectors or yellow. One of those is your SRS and you could cause a air bag to blow.

My oil light suddenly goes on & makes noise- the 1999 Town & Country stalls once in a while-what could be the problem?


Could be time for a new van.
The oil light is warning the driver engine oil pressure has dropped below 10 psi, not necessarily that the engine is low on oil.
Common causes for low oil pressure is a faulty oil pump or screen, or worn engine parts.
The fact you are also adding coolant and you don't see any external leaks sounds like the engine is reaching the end of its life.

1999 buick century..my temperature guage sometime goes in the red and then back 2 normal...once it does that it takes my car awhile 2 heat up


Hello! Replace the thermostat, it is defective...I would suggest flushing the cooling system with the heat set to high...Your engine requires Dex-Cool anti-freeze...It, due to electrolysis, has a tendency to "clump" blocking proper flow...Drain the cooling system...Fill with plain water...Allow engine to heat up and when the thermostat opens shut down and drain...Do this three times or until water is clear...Replace thermostat and refill with Dex-Cool...Allow all air to escape before installing cap...

While driving my 95 explorer i noticed the heater wasnt getting hot its luke warm and when i turn on the defroster i start to smell anti freeze and all of the windows fog up


no heat is probably low coolant or bad thermostat,although you have fog and smell ! the heating and cooling systems are closed systems the only way the windows fog is the coolant is hot and steams inside the car due to some leak inside the heater core box. as well as the smell being present. Now it is possible that a little leak has occured where the coolant supply or return line connects to the heater core and is running into the car which is running onto the core and creating steam and smell. hopefully it is a easy clamp tighten fix for you.

The coolant sensor light is on


The coolant sensor liight come on when the Anti-freeze get low. Just top off the ant-freeze and the light will go out. It is norrmal for anti-freeze level to go down but slow. Toping off once or twice a year is ok but anymore then that you really should check for leaks. Low anti-freeze will cause over heating. Over heating can wreak an engine.

99 suburban leaking from oil cooler fitting on radiator


It sounds like you might have a crack in the plastic tank of the radiator. If the line was leaking, I would think you'd see some oil leaking. Any anti-freeze leaking? When the truck is cooled down, I'd check the anti-freeze and oil level.

2000 Grand Am GT: My 2000 grand am is leaking antifreez from behinde...


Hate to tell you but it sounds like you have a blown upper or lower intake manifold gasket. This is a very common problem with these cars. I have had mine replaced twice in 150.000 miles. It has been recalled a couple of times 4 or 5 years ago. Its not a cheap fix it ran me about $800 to have them both replaced. If this is found to be the problem when your having it fixed have the garage working on it flush out the complete cooling system of the Dex-col type anti-freeze so it can be filled with regular anti-freeze when there done. Dex-col anti-freeze is the biggest reason these gaskets fail. It eats through and breaks down the gasket over time. But its best to have a garage flush out the system due to the fact the two types of anti-freeze cant be mixed at all or it will turn to a gummy substance and clog up and ruin water pumps , radiators, and heater cores but flushing the system good will keep from any small amount of Dex col being left in the system. In my opinion the regular anti freeze keeps the engine cooler and is twice as cheap not to mention that its gasket friendly

What does it mean when transfluid get into the coolant


The transmission has cooler lines that run to and from the radiator. The fluid is cooled, by running thru tubing inside the one side of the radiator tank. The tubing probably has a leak, causing anti-freeze to get into the transmission. This MUST be repaired, due to the fact that the anti-freeze will do some damage to the transmission.

Oil in coolant . oil cooler bad but which one


Oil generally will get into the coolant due to a headgasket leaking, or a cracked head.

You'll need to pressurize both systems (OIl & Cooling) to try & determine where the leak is coming from. .

Antifreeze in the oil can cause the pistons to sieze in the cylinders and if you've got oil in the anti-freeze, you more than likely have anti-freeze in the oil, or soon will.

Good luck.
