Coolent overflow

[mustangGT2001]

hello all I have a 2001 gt that had new engine installed with all the internal goodies, I have a blower and have not boosting now for about 350 miles, today driving home as i got off the car i smell coolent so i open the hood and i have one of those canton tanks and the coolent was coming out of the vent drain next to the cap now the gauges were normal and the car was not overheating, the condensor fan works good with the AC and when the car sits it also kicks on, any ideas of this problem and have anybody experanced this before,

BTW when it cooled down i looked the coolent level and it seamed ok were it suppose to be maybe somewhat lower but still had fluid.

Have you checked your intake manifold for hairline cracks yet? could be leaking out of there.

i looked all over only place it coming out is the overfill drain i can see it when its happening just under the tank cap btw it a new Ford racing intake with the aluminum water passage and the car is running the same, looks like the tank get over filled and starts to dump funny deal

If the temps showed OK it could be that there was too much fluid in the system. Have you recently filled it? Also make sure the radiator fan is operating properly. It should come on when the car reaches operating temp around 210 degrees with the AC off.

I replaced the nipple with a plug on my Canton and haven't had any problems in 2 years.

I just got done looking at the coolant level on my Canton Tank and it was 1 1/2"-2" below the relief valve, and I'm sure mine has'nt lost any fluid out of that drain. If you don't already, go to an auto parts store and get about an 8" long clear plastic tube (I can't remember the size) and stick it on the end of the relief drain and aim the tube downward towards the ground, so it does'nt shoot any excess fluid onto your engine. They did'nt put that drain there for their health, so I would'nt plug it up.

Just sharing "MY" experience, since the factory tank didn't have a drain like the Canton and I haven't had problems in 2+ years.

Check your radiator cap. That drain plug should let out fluid if the cap lets it. (pressure gets to high for the cap to handle)
