Question about 2001 Chevrolet Blazer
When I turn my heater on after the blazer sitting a while it has a sweet syrup smell. I thought it was the heater core but my floor board wasn't wet from antifreeze and I check my radiator and its at the same level. I have a small leak from the water pump though.
Hi, fix the water pump leak,the smell could be coming from he antifreeze burning off the hot engine .

You have a coolant leak most likely in the heater core. Try disconnecting your heater hoses and coupling them together, then running the engine to see if the leak goes away. If it does, I would have the heater core replaced.

you could quick fix! but you will have no heat, 1st under the hood, look at the back of motor, follow all you're radiator hoses, take two hoses off the heater core stick a pipe that is big enough then clamp the pipe down. to both sides of hoses to the pipe you will eventually have to replace heater core!!

Usually a smell of antifreeze in the cab when the heater is running is a sign the heater core is leaking. Just becasue you dont see a leak at this time doesn't mean there isn't one. It might small enough that the haet from the core is burning off the leaking antifreeze. I would suggest replacing the core before you get in one day and there is a puddle on your floorboard. Or if you go to a local parts store and rent a cooling system pressure tester, wait until the vehicle is cold, pressure the system to 12 lbs and then check for leaks. Hope this helps you out......

Testimonial: "that is what i also thought, no puddle yet, just waiting. I tried a sealant for now, but will get a heater core"
1997 Chevy Blazer... my heater puts out small amount of heat, and its a cool heat, not hot like it should be. Also when fan is running on the heat side, its not as full forced air as when I switch it to the cool side. Can't tell if its the blower, something is stopping the air from flowing all the way, but then again, what air is coming through, should be hotter than what it is.??

The heater core is not plugged, it is leaking and will have to be replaced. It will have to be accessed from under the dash on the passenger side. This can be a very difficult item to replace and very time consuming. Plan on it taking a full day.
