    Bypass Heater Core.

    My Heater core gave out and its the middle of winter. I am trying to bypass it so I can drive it somewhere to get it fixed. I removed the tube from the overflow reservour and atached a tube to the back of the engine bypassing the heater core. I removed the fuse to the heater core. The car is overheating but not steaming up the interior. How do I get good flow to the cooling system. Thank for your help.

    Thanks, I read the info. I am wondering if I put the overflow reservoir directly to the coolant with a straight hose if the coolant will flow properly. I see no leaks but it started to overhead and I think there could be air in the system.

    thanks

    Car shouldn't overheat due to the bypass

    Check to see the long plastic pipe from radiator going around the engine bay back to the expansion tank is not plugged; also check that the auxiliary fan can be automatically switched on. Another (unlikely) possibility is that your car may have been relying on the Cabin Heater core to dissipate some heat so as to maintain the operating temperature.Patrick C 88 750 159K
