Coolant leaking from backside of motor

Coolant leaking on backside of motor by firewall, look unerneath and its coming between motor and tranny on top side cannot see where leak is coming from myself. possibly could be heater hose , hopefully not a freeze plug. any help plz would be appreciated, the leak flows it seems in cycles, not steady but in cycles as though only when the thermostat opens up or when it travels into the heater core, regardless , any help on this would be appreciated thank you.

The cowling for the wiper transmission is in the way for a clear view but take a mirror and try and look at the back of the intake manifold. Very common for them to go bad.

Hello, i am about to buy a 406 deisel either 53reg or 54. the problem is there is clutch fluid leaking and you have to keep topping it up, can you tell me please if this is going to be a costly repair or...


ok do this lay down on the ground look under the car and l;ook see where the fluid is leaking see if it is leaking from the transmission or a hose if a hose could be 10 dollars of the transmission could be 2 grand thats why gotta check it check the hoses by the clutch fluid reservoir alot of times leak there cause hoses old and the heat from motor rising deteriorate faster then normal check the tranny see if it all over tranny then i would pass on the vehicle but if its just on the firewall then probably be ok be sure take flashlight to check it out so can see tranny and firewall make sure tranny dry

freeze plug or intake. Most auto parts stores sells a red dye you can add to the coolant. Then you need a ultra violet lamp to see where the leak is. The dye will show with the UV lamp with a bright glow

it is most likely the hose that goes into the heater core next to the firewall hard to see it though. The things have a tendency to leak form the bottom of the line. more so when on, and circulation less.
