Large Coolant leak

2004.5 2500hd cc 134kmiles duramax

I have a large coolant leak while truck is sitting not running...

I just got the truck noticed heater not working that well...

Noticed large pool of coolant in 4 hours...

Leaking on passenger side near wheel well...

Any direction or ideas would be great... It was dark when I saw it so I will look for the easy fixes in the morning.

Thanks for the help this is my firzt duramax, always had powerstrokes... Hopefully this is not the future of the new truck.

Thanks for the help guys,
Jason

check your heater hoses that come out of the cab on the passenger side. The hardline could have a crack

Well I am glad the first two responses did not mention head gasket haha

I did pop the hood and looked like it could have possibly came from the surge tank but I am not sure at all, too dark

Thanks for any more suggestions

Had co2 test done on coolant and it did not change color indicating a HG leak... everything I read online is always the horror story of blown head gasket.

This morning truck was showing it was running cold and the surge tank was pushing out coolant than it seemed that something opened and the truck temp read normal, the heater blew hot and the low coolant light came on. Because of the loss of coolant before it opened. t-stat issue?

Any suggestions...

You know what it is. Head gaskets, unfortunately. Fill your coolant tank to the brim and let it idle with the coolant cap off. Initially, it will push some water out as the fluid expands, and probably as exhaust enters your cooling system. After a minute or two, I would get bubbles the size of nickles coming to the top of the coolant tank every 15 seconds of so. Hope it's not, but exact same symptoms as I had.

Upper radiator hose hard in the morning?

Ya I am keeping my fingers crossed that its not a head gasket.

I changed the coolant tank cap and seems to not be pucshing coolant out since I changed it? Could it have been a pressure relief issue?

$7 fix is a little better than a $4000 fix

Possibly. If your cap was bad. I tried that too. Mine was building pressure and pushing coolant out. It started very occasionally and got progressively worse over a 6-7 month period. It never overheated. Good luck!

If I get the cylinders pressure tested, it will determine the verdict 100% correct?

My next step will be t-stats... Because it had heating issues before I put the new cap on...

I will be getting the heads tested if it happens again.

Any more stories or suggestions, would be appreciated

Thanks

After you drive it, let it sit overnight and squeeze the upper radiator hose. It should be pretty easy to squeeze. If it's hard then it usually means its a head gasket.
