    Default Coolant leak or heater core issues?

    Hi,

    My truck seems to be leaking a lot of water or coolant after I drive the truck. Dash says my coolant level is now low. There is a lot of liquid being dispelled from the hose underneath the AC condensor by the firewall.

    I rarely run my AC. And I've had on going issues with my climate controls since for the past year. AC sometimes works when it wants to. Normally, the AC is fine on the hwy and crappy on the streets. Heater sometimes kicks in and somethings won't.

    Can anyone give me some pointers here?

    Yep, looks like my heatercore is leaking. I was driving today and my vents were smoking. I'll try to hit it with some Alume-seal, hopefully that will fix the problem.

    Maybe I'll just bypass the heater core completely.

    Can anyone tell me what size the tubing going in and out of the firewall is?

    So, I just decided to bypass the heatercore and go without heat all together.

    1 year later, finally attempting to replace me heatercore. Ordered everything I need and starting next weekend.

    what you will need is alot of time to remove dash.
