Good morning,

After arriving at work this morning I walked back out to the truck (99 d1 with 136000) to grab something and noticed coolant leaking out from under the truck. After opening the hood I found a hose with a pin sized hole in it spraying coolant. The hose comes off the block and runs into the cabin. My question is can I just replace the hose and refill with coolant? What else do I need to do? The last thing I want to do is blow a head gasket. Thanks so much in advance for any help!

 

sounds like the hose that goes to the heater core. yeah, just replace and top off with coolant.

 

Thanks so much! Do I need to bleed the system after I top it off? Also (stupid question) but how full should the coolant tank be? I can't see a fill line. Thanks again for the help!

 

You shouldnt need to bleed the cooling system, you wont lose that much coolant. Open the resovoir bottle and you will see a "X", coolant needs to cover that.
