I have been having problems for about 1 1/2 months. My dash gauge never indicates it is overheating. Within this time both heater hose tee's have broken. One of the new ones only lasted about 2 weeks before it broke on all 3 connections. Now the heater hose connector broke. Does anyone know what could be causing this?

 

Are they plastic or metal? Possibly putting too much pressure on them during installation and cracking them.

 

They are plastic.

 

Hi.
Yes. As it was said that the plastic connectors were cracked from long operation.




But maybe that breaks down the plastic from bad engine mounts. Engine vibrates and breaks down the plastic.
