2006 H2 coolent problem
 

I have a problem, since December my truck will drip coolent every now and then. Not everyday but it happens. i marked the coolent bottle and it isn`t dropping. some days the drip is only a small one on the scid plate. And others it looks like a tennis ball size. but the bottle still doen`t look lower.

Anyways I pulled the skid plate and lifted the truck up on a hoist. I do not see any leaks by the rad or the water pump at all. it is on the passenger side I see by the oil pan two wiring harnesses. I do see some coolent on those but cannot back track it to any leak.

I also did a pressure test and it did not force any visable leaks to show either.


so would any body have any ideas what this could be????

If the puddle you see is clear water then it is condensation from the air conditioning compressor.

no it is red and sweet. and it never puddles

heck it could be the water pump going out. It starts to leak a little bit of coolant when its time for it to go out.

I have the same thing going on to , and sometimes the wheelwell gets wet

My guess is the water pump, I know you said you checked it but a lot of the times especially a slow leak like that is hard to detect. They usually leak out of a small weap hole at the bottom of the pump after the truck has warmed up then shut off to sit. As it cools down that's usually when they leak.

Yep the water pump can leak for one day and then quit for a while and then do it again. If that is the case you should be able to see a dried up trail of coolant coming out of the water pump weep hole.
