i've found a small amt of cooling collecting under the car lately. today, i had the front up on ramps but couldn't tell where the leak was coming from. a couple weeks ago i added some premixed dexcool to the radiator. could i have put too much in?

if you really can't find where it is by just looking, you can get the flourescent dye and use a blacklight. Did you check by the water pump?

i've checked by both heads and the front when i was underneath and couldn't tell. if i do the dye thing, will it hurt the engine at all?

Check the weep hole on the water pump.
If it is the weep hole, you may also find orange coolant "residue" on the engine pan bolts (looks like orange grease).

the dye will not hurt the engine - have dyes for all fluids- oil, trans, coolant etc. works really well especially in tight spots where its hard to see specifically where its coming from & you can find the bottom of the "TRAIL" & follow it up

one more thing look at the water pump notorious for leaking from the weep
