Ok so I have a pretty substanial coolant leak on the passenger side of my truck. I thought it was the lower heater hose (one that runs to the water pump) replaced that yesterday drove it around, and the leak is still there. What else might I check for? is there a freeze plus on the lower passenger side of the block that could be leaking. The leak is pretty constant and drips to form quite a large puddle. I can't seem to see where its coming from other than it is in the vacinity of the heater hose. Hose however is dry.

 

Any Ideas I am open to anything that might give me a lead?

 

There is a freeze plug on that size, it's where I mounted my block heater. Should be able to see it through the wheel well, I did not even have to take off the tire to do the block heater.

 

Check the water bypass on the heater core.

 

check the heater control valve their bad to leak

 

Thanks got to look around yesterday and I noticed that there was coolant leaking from the top down to the bottom from when I replaced one of my heater hoses a few months back. Pulled off the upper raditor hose and re-adjusted the hose clamp on the heater hose and so far no more visible leak, and certainly no puddle under the truck. thanks for the tips on wear to look I will check those out too today.
