I have a coolent leak in my 85 12A and i cant find out where it is coming from. I did the bubble test to see if there was air in the radiator and didnt find anything. I have found 3 hoses on the pasenger side of my car though that dont have a conections. One of them i think is the drip line for the A/C but i have no idea what the other 2 are. I you could tell me if they are the sorce of my problem i would be greatful. One is between the intake and exaust manafold facing towrd the fire wall but then bends down. There is a mark where a hose clamp used to be on it. The other one looks like it is coming off the back of the black and heads straigh down. it was eather cut or dosent apear to have had a clamp on it. I have pictures and i will upload them soon for clarification

 

toyota coolant is red and it crystalizes as it leaks, making it easy to find leaks.

$11 from toyota/lexus dealer

IIRC there is a gasket & O-rings at the interface of the rotor housings & the intake manifold. Look above & below the intake manifold for wet........ Or retorque the intake bolts & check results.

Happy New Year ; )
