I want to find a easy way to help the coolant go inside the engine.

I went autozone yesterday, they are selling a product to seal the broken gasket of the engine then prevent the coolant going into the engine.
it sounds easy to use, just put into the radiator, that's it.. the bottle costs around $60..

anyone try this before? does it work?

Fixing the seal would be the best way to go, stuff like stop leak in a bottle are band-aid fixes.

What exactly is leaking? Headgasket? Tell us more info.

no sure what leaks yet. did the oil change last month, the guy found some coolant mark on the oil cap.
he said that it look like the coolant going inside the engine, might be the head gasket or other issue.

Lot's of short haul driving where the engine never gets really warmed up? That could be condensation, not coolant.

It takes at least twice as long for the oil to get to operating temp as the coolant. If the oil never gets really warm, you can get
condensation in the oil which makes the white goo.

How many miles on the truck? Every had a real overheat?

Personally - I wouldn't put the "magic" gunk/sealer in my engine.

I think the general idea behind these "sealers", is to thicken or treat your fluids in a way so as to "coagulate" it and it gets trapped in the leak somehow.

Thing is - what if it gets trapped in a place you DON'T want it to be trapped? now you got junk restricting fluid-flow, which may end up costing you a whole new engine.
Personally, I'm scared sometimes to even put cleaners in any of the fluids/oils - unless you know it's nice and "clean" inside, then it'd be a periodical maintenance thing - not a Fix-All.

Like TownCivilian said - most likely those "fix all" gunk/sealant stuff is a temp solution, and it'll only come back again sooner or later.
I say just do it the hard and $$ way - send it to a reputable mechanic and have them fix the leak/seal.
Or, if you're mechanically inclined, tear it down yourself and replace the seal.

my QX4 has 115k miles on it now, so far , the temperature is kinda normal so far. I drive around 100 miles everyday. but the previous owner just work around two blocks away from his house, so, maybe the car is not warm up enough everyday then cause this issue..
