leaking coolant by thermostat!

[rmb1393]

Hey guys i have a leak by my thermostat housing and i am loosing coolant. there is also a fungus like substance by my thermostat that i assume is attributed to the leak. i'm going to try and attach a picture...

[rmb1393]

well the picture didn't work sorry about that but do you think this is my water pump or should i just do a flush and replace thermostat and seal?

Didnt see pic but our trucks are bad about leaking out the thermostat housing. Order a billet one from dieselsite. I just fixed mine and now the water pump is leaking out the weep hole

Where is the weep hole located? I want to make sure its just the housing and not the water pump. Where can you get the billet housing? Is it just the elbow for the t-stat or what?

Diesel site. It's a billet thermostat housing

Weep hole is under the pulley. Dieselsite.com

Thank you both! Is there an o-ring that comes with the housing?

[gomer pyle]

Yes. But i used permotex also

Is that silicone based sealant?
