i have been losing coolant for the last couple of weeks, and despite all my efforts to locate the leak, i failed. today i got out of my truck and could really smell coolant. got the spot light out checked all the hoses, and then noticed the block was wet on the drivers side. the gasket is leaking to the outside. no water in exhaust or in the oil. this is a first for me. mine have always let water into the oil and not leaked to the outside. any ideas why?

 

I have seen this on a few trucks. But, thankfully, not on mine

 

yeah my coolant leaked out of the back to that realy common also. however i also got it im my cylinder

 

Mine's been leaking like that for more than two years now. Just call me lazy that I haven't fixed it yet

 

My old truck leaked out the driver side also. It didnt really affect anything but I replaced it anyway.

 

I just replaced a head gasket on my truck that was only leaking radiator fluid
on the drivers side in between #1 and 2 cylinder. I had slightly lower
compression on the #2 cylinder but might have been from my old cylinder
head that was burning oil. I didn't have radiator fluid in the oil either. Same
thing happened to my 4runner.

I think it might be from these two things:

Corroded away coolant ports which allows fluid to absorb easier into the gasket making it weak.

Overheating or just building up too much pressure in the coolant system.

 

It is rare but I have seen it to , sure its not leaking around from a freeze plug ?

 

IIRC Cebby's old 3.0 blew the HG with an external leak in the back.

 

the freeze plug, yeah thats what i was gonna say. mine is leaking out of the freeze plugs. if the freeze plugs is all thats leaking, then id say dont worry about it unless you dont like cleaning up coolant, just keep an eye on the coolant level.
