I have a Q re: the termination

I have a Q re: the termination point of the long heater hose on an '85 308. I see that the hose runs waaaay under the dash cowl in the front and connects to a T fitting (on the fire wall) from which a smaller diameter hose emanates. Does any coolant pass through the firewall to any internal hoses or mechanisms or is that fitting just a mounted connector for these 2 hoses? Given the location of this fitting, it'll undoubtedly be a bitch to reach. If it's only a connection point between 2 heater hoses, couldn't a reducer fitting be used between these two hoses at a more reachable spot--or is there some other function for that connector on the fire wall?

Hi Bill,

it's just a connector for the crossover hoses.

To answer the second part of your question: To the best of my memory the hoses are simply routed to keep them out of harms way. Hot water comes in to the heater valve on one side, passes thru one heater core while the other hose goes to the other side heater core, then the water returns, comes together and exits to a front main water pipe below.

Bill,

Bill,

I recently had the pleasure of replacing the heater hoses. The best way that I found was to attach the new hoses to the old ones on the left and right heater cores. Once this is done simply reach in and gently pull the "T" juction out as you feed the new hoses through. Then disconnect the old hoses from the "T" and pull them through to attach the new hoses. Then reverse the process to re-establist the "T" .The "T" itself is not connected to anything. Then attach the new hoses to the heater cores.

Hope this helps ........Gary
