Coolant smell no leak.... Help

Any mechanic will have one, some auto parts stores have them too. Here is one available online:

Check all your hose clamps too, especially if you have switched any of your hoses to worm clamps that you tighten with a screwdriver.

Basically, the weep hole is a way for the water pump to let you know it is going bad.
http://www.nabiki.com/sstalker/626_h2o.asp
Because the pump runs constantly (well, whenever the engine is running) the part of it that almost always fails first is the sealed bearings for the pulley. The manufacturers of the pumps have taken into account the eventual breakdown of this component by including a way in which its failure can be detected by either the car owner or an auto mechanic.
The housings on all water pumps include a small weep hole near the neck of the pulley which will allow coolant to escape should the seal on the bearings be compromised. This hole, which actually faces upwards on the pump housing on a 1993 626 V6 (in most other engines it faces down) should be inspected regularly once your car's engine gets past the 85000 mile mark. If you ever see moisture collecting around that part of the pump housing, or more likely if you happen to notice a small puddle of antifreeze on the ground or detect the smell of it wafting from the engine, the pump is probably on its way to failure.

Where are you getting the odor? If the engine is running and hot (or just turned off) and it's noticeable in the grill area and/or under the hood around the rad. cap or the expansion tank only and you have not actually had a noticeable drop in the coolant level in the expansion tank, then you may just be smelling the system venting.

The obvious thing to do is pressure test it and check for coolant loss. If there is no significant loss, I would not worry too much.

Lontar-check the radiator cap too. It could have a tear in the rubber gasket or isn't holding pressure like it should. Look around the seams of the radiator where the top and bottom are attached to the body of the radiator.

You need a new radiator, the plastic shroud on top of the radiator is crimped to the aluminum section of the radiator. I replaced the entire radiator and it costed me $150, no problems with aftermarket radiators.

I would get the all metal option radiator, which appears to be the second link.
At least your has a small leak, the radiator in my old 626 blew out the side, had to add water every mile and a half to get home. Not a fun afternoon.
