In the bottom of the radiator... there is a nipple that allows the connection of a hose, the observation that you make about the leak, is located in the nipple (could be a crack in the solder?) or you refer to hose itself. If the hose could be two things:
- Leak caused by a bad fit in the bracket
- Leak caused by dry, cracked hose

Check and make their comments.

Lower radiator hose or core


Before you go replacing a radiator, you need to check out why the quick overheat. Most likely due to low coolant which indicates a leak. Yes the core could be leaking...but it is not the most likely problem. If there is coolant dripping from the lower hose, it could be a simple matter of the lower hose clamp just needing to be tightened. They do work loose occasionally. Check the clamp, and tighten if needed. With the vehicle cold, check and refill the coolant in the both the radiator and the reservoir bottle. Run the vehicle to normal temperature and observe all connection points. IF no leaks are seen, use the vehicle normally and monitor coolant level for a week or so to ensure that you have solved the problem. If you are still loosing coolant, but have no visible signs of loss (drips or puddles under vehicle), then the problem could be a worn out water pump. They often tend to leak only when running and the lost coolant often evaporates on the engine block out of sight.

Leaking coolant but not overheating


Can you identify WHERE it is leaking from? Is it just a slight dribble and a bit of steam, of a major leak where it is running out?
If it is from the rubber hoses or near the clamps? Your vehicle is quite old and the upper/lower radiator hoses may have to be replaced. A fairly simple loosening of hose clamps with a screwdriver or with a pair of pliers and then just levering them off their housings.
But first get a large sheet of cardboard or plastic and a shallow pan to catch the coolant as you let it drain. Let the engine cool first... test if the internal pressure has gone down by squeezing on the upper radiator hose... if it is easy to squeeze then it is safe to drain and empty the radiator with the little winged tap that is just on the lower, inside of the radiator. Loosen the radiator cap to allow air to enter the system and let the coolant flow out. (Careful with pets... they seem to love drinking the coolant... but it is poison!)
You can now change the upper/lower rad hoses and heater hoses and maybe a short by-pass hose.
IF the leak is just a minor seepage from the radiator or inside the heat core (you likely can smell the vapours of the steam of the leaking coolant inside, the likely cure is to my some "radiator stop leak" from an auto supply store. Follow the directions on the bottle, but most have a syrupy liquid and little metal pellets. You open the radiator cap (when it is cool or depressurized) then add the small bottle of radiator repair solution. Put the rad cap back on and then you have to go for a reasonably long drive (usually 30 minutes or so) to heat up the pellets and have them "melt" as little flecks of soft metal in the solution. The idea is that as the coolant attempts to leak out... these little metal flecks block the leak.
IF you have the coolant totally dumping out and it is not a leaking hose, it may be the water pump and seal. I think I'd suggest that you get a mechanic to deal with that.... it is not an easy task for a DIYer !
I sincerely hope this helps. Please let me know...

I am having a problem with antifreeze smell and leak. I can't see where the leak is coming from but I do see spots on the ground. It does not over heat but it does have a sent of pancake syrup once heated....


LEAK COULD BE COMING FROM RADIATOR.WHEN YOU FIRST START VECHICLE UP IN MORNING LET ENGINE IDLE TO GET UNTIL THERMOSTAT OPEN AND COOLANT PRESSURE BUILD UP. TURN ENGINE.OFF. RAISE HOOD YOU WILL SEE LEAK. THE COOLANT PRESSURE WILL PUSH OUT ANTIFREEZE.LOOK FOR LEAKS AROUND TOP RADIATOR HOSE AND LOWER RADIATOR HOSE.LOOK ON SIDES RADIATOR AND LOOK BELOW RADIATOR AREA WHERE COOLANTS FANS LOCATED RADIATOR CORES WILL LEAK AND LOOK AROUND WATER PUMP + BYPASS HOSE + CHECK HEATER HOSES TO HEATER CORE THAT GOES THROUGH BACK LOWER FIRE WALL.

1998 buick radator how to drain it


Make sure the engine is cool, then undo the hose clamp for the lower hose clamp to drain out the coolant. Refasten the hose clamp to the radiator, and fill it up with 50/50 solutioin of green coolant to water.

Where is the engine coolant drain bolt on a 2003 2azfe camry? i found the radiator drain but can't find the engine drain plug-a photo would be great


The textbook method is to remove the drain plug on the bottom of the radiator.

Most drain plug is make of inexpensive nylon/plastic and it may fall apart while you turn it.

The professional method is to loosen the lower radiator clamp and drop to lower radiator hose.

Drain the coolant onto a large drain pan and recycle the coolant
