Coolant leak near trans

Hey guys,
I just came home from a week long trip and have a pool of coolant in my driveway (‘04 Tundra) The leak is coming down near the trans but is definitely coolant. The weather got down to -15 when I was gone and was not leaking before I left. Attached are pictures

 

Either coolant leaking from the crossover at the top of the engine or the freeze plug behind. The transmission. Try to see if there’s coolant above the transmission. If not it’s likely the plug that involves pulling the trans

 

There's been a few people who reported their tundras were "pissing" due to cold weather. I think @Mr.bee was one of them, and a few others.

 

Mine is oil. Either engine or PS.

 

I just checked and there is coolant coming out of the top of the engine somewhere and you can see coolant below the intake. See picture

 

Looks like it’s time to do the coolant crossover gaskets. Since the manifold has to come off you may want to do the starter too

 

Sorry, i had assumed wrong. Stickiness must've been a figment of the cold. But i'm dripping up front.

its the rubber coolant hose that attaches to the oil cooler. I can see where its split at the end of the nipple.



best i've found is the hose kit from yotashop.

@empty_lord could it be the TB coolant lines with it being that far forward under the manifold?

 

Unlikely but possible. There’s coolant crossover pipes at the front and the back of these engines. The gaskets are well worn by now with age

Thanks for this. I am going to fill the coolant this weekend and see if I can see where it’s coming out from. Did you have to remove the intake to get to those o rings?

 

Refilled the coolant this weekend and none is leaking out. I drove it for about 30miles and coolant is still full. Seems strange to me but will let you guys know if it starts leaking again. Only thing that was different the week it was sitting was that it got so cold (-15 deg F)

 

Did you park it at a slight angle ?

 

I parked in the same spot where the leak happened originally where it is flat

 

Fluids clean and full?

 

My leak would only happen at an angle, keep that in mind. Coolant collects in the block and drains down the holes in the rear
