LOSING WATER WITHOUT STARTING CAR
I fill up water in radiator cap and in about 30 minutes its gone. Cant find any external leaks
but there is water under internal carpet
Sounds like a leaky heater core which is located behind the glove box.
Heater core is done. DO NOT USE SEALERS IN COOLING SYSTEM. radiator and cooling system damage will result
Thanks Tom is it a big job to change ?
are you sure its the heater core and not the water pump ?.. Just asking
Can you disconnect the hearter core and use the car while waitning for parts. ?
I can't be sure unless I'm inspecting the vehicle, I can only guess on a forum like this. You can try connecting the hoses in the engine bay together to bypass the core, but then you won't have heat. Best to get it fixed properly. Here is a link I found that describes the process. You have to evacuate the AC system properly , and removal of the dash. A big job best left to the pros.
