Question about 2001 Nissan Altima

1 Answer

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

I have a 2001 Nissan Altima and it only has 96,000 miles. I smelled antifreeze and opened up the hood to see that there was a small bit of antifreeze or coolent around the radiator, upon further examination however, I noticed that the metal lip that circles around the radiator was covered in a slightly larger amount of antifreeze. The cap to the radiator was secured and there did not appear to be any other issues. Any help is appreciated.

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.

SOURCE: 1995 Nissan Altima ticking noise

1. Will need a radiator; there is ruber seal between the plastic tank and the aluminum core, and it sounds as though the seal is bad. I've tried transmission sealers; sometimes they work for a while.

Ticking noise is probably lifters (cam is farther down in the engine). Outflow of air from oil cap is normal. JWS

SOURCE: replacing the radiator system for nissan altima 1998

Drain coolant from the cooling system. White plastic drain plug in bottom of radiator.

take off bottom rad. hose and top rad hose.

All wrenches and sockets are either 10 or 12 mm. Remove air shroud from around radiator and fan.
Sometimes its easier to remove fan too.

If its an automatic, remove 2 rubber hoses at bottom of rad.

remove 4 bolts top and bottom that hold rad. in place.

reverse order of parts. Fill with coolant and check for leaks.

That is the basics of it.

SOURCE: my 2005 nissan altima antifreeze fluid started

Leaking head gasket. If a V6, replace both head gaskets.
Oil is seeping past gasket and getting into the coolant port holes.

Antifreeze smell

If it's not overheating, you may need to replace the radiator cap. Also look for small leaks at all your hose ends. Their could be a loose clamp on your hoses.

Smell antifreeze inside car

If you don't see any antifreeze leaking in the engine compartment (especially around the radiator) you could have a leaking heater core. Does the smell go away if you turn off your heater for a while? If so, that's likely where your leak is.

My 2001 town and country limited is overheating without indication from the gages and has a burnt smell coming through the inside vents of the van.

  • This I understand, a burnt smell coming through your vents, but how do you know it is the engine overheating? You said you have no gauge warning. Is your antifreeze disappearing? In other words are you having to refill the antifreeze? Is the van stopping and steaming? Stalling? The reason I ask is if you are not loosing antifreeze something else could be going on. Antifreeze does not smell "burnt." Antifreeze smells sweet like cinnamon. Give me some more details like what going on other than the smell and how is this effecting the driving of the car?

I had put dexcool anti freeze in my 2003 altima nissan now it's smoking a thick white smoke from my exhaust

Dexcool antifreeze cannot be mixed with any other antifreeze except the new all makes all models antifreeze. If you mixed it with green or any other antifreeze it becomes toxic & will eat away from the inside out. Try flushing it all out, but it sounds like you blew a head gasket & may have hurt other cooling system components.

Antifreeze leaks out as soon as added to engine. car shuts off as soon as all antifreeze leaks out. what could be wrong? when antifreeze leaks out so badly

Depending on the mileage & other facters unseen I would hesitate a guess! You may have a blown head gasket, A frost plug leak, a water pump leak. Have a rad pressure test done to ascertain the leak location, but you can first check the tail pipe for antifreeze smell, if you smell it you have a head gasket problem. Also check the oil dipstick to see if you have any traces of white residue, an indication of a head gasket leak. I hope this helps & good luck!

Antifreeze smell

If u smell the antifreeze inside the car, the heater core needs to be replaced most likely. It is leaking inside, and will get worse, to the point of 'fogging up' the windows inside.
