was it the red crap or liquid glass. also was it running when u put it in.

 

hmmmmmmmmmmm sounds like a water pump

 

Get under the truck on the passenger side and look up at the exhaust manifold.

12v's are known to crack the cylinder head inbetween cylinders 5 and 6 and it will start out as a small leak or coolant loss that you can not find.What it does is leak down the side of the block and over the bellhousing blowing back underneath the truck.It may not even show until the crack gets worse and it really starts to leak.

Mine started as your did many years ago and the only way I knew I had an issue was a faint coolant smell and adding to the overflow bottle about once a week.As the crack got worse it was easy to find as it began leaving puddles when it was parked.

 

mine blows it over the motor and covers everything i happened to polish. and mine was liquid glass and it was cold when i put it in then started it. it nevers leaks out onto the ground

 

i never have a leak on the ground either. thats a good possibility cus i have tested about everything else.

 

everybody keeps telling me its the head gasket under the thermostat housing. but everytime i look there there isn't anything there

 

i looked at another one today that they wanted me to put a new thermostat in. they thought it was leaking. it was the head gasket not the T housing. hes pissed. he had it done less than a year ago on a stock engine.

 

mines leaking due to a rotted out head gasket by the t-stat, gonna try to replace it this weekend, gotta get the truck ready to travel, sucks to do it tho

 

ya i don't want to do mine yet i have to get to work everyday

 

i guess the head gasket is too thin there and if you dont retorque then it blows
