my 99 v6 is leaking coolant from the front of the motor......it seams to becoming from a small black tube that goes into the back of the housing that the upper radiator hose connects to......any help????

 

the leak is coming from the front cross over pipe, replaced the o-ring and the 2 gaskets on the front of the heads

 

is that a hard repair........but thats where it is leaking for sure...thanks....

 

look at the drivers side t-belt cover and see if you see coolant traces on the cover if so then that is it, it is not a very hard repair there are 5, 12mm head bolts and then you can pull it back and remove the o-ring and the gaskets and put it back together, make sure you put a little grease on the o-ring so you don't roll the ring

 

yes i do see coolant on the timming housing....so you helped me find the leak...thanks....also thanks for the idea for the grease...i'll let you know how the repair goes......thanks again

 

i repaired the cross over tube and it was an easy reapir....BUT when done i ran water over the top of the motor to clean and coolant away and saw what appears to be a new leak on the back of the motor???? i think it was the water that collected in the valley and ran back...after a few days the water stopped comming from the back of the motor but i still seam to smell antifreeze but no spots under car???? the smell drives me CRAZY....but i'm crazy about that kind of smell..i can seam to smell it only a little...the reason for the rant is that could i have damaged a diffrent seal working on the front cross over tube..the original leak was from the o ring that goes in to the front cross over tube..is there a rear o ring on that black tube???i goes under the intake and i can't see where it goes???? OR is the smell just from antifreeze left over from the repair and how can i rinse it away???
