Go to a parts store and pick up some of this stuff if you can.



I've used it a few times and it worked well enough to get me to where I needed to go so it should get you the 50mins home and further.

 

i bought the stop leak today, then undid the radiator cap, and it was full, this left me quite confused. what am i missing?

 

What about the res tank? Might have been a slow leak.

 

the one labeled engine coolant? it does look a little low

 

has anyone located an aftermarket all aluminum radiator that fits well?

 

That plastic coolant reservoir is what you generally add coolant to - it's used for overflow as well as to pull in more coolant as it's needed (temparature expansion & contraction). This is where you add coolant to, leaving the rad cap alone. This plastic reservoir can develop leaks (cracking on a seam or chafing - I've drilled holes in some not watching what was behind a place I wanted holes to put on fender flares), so I'd have a close look if you are in fact leaking coolant - see where it's dripping from and try to follow that back to the source.

 

I agree with Alfons, you may have a slow leak somewhere... Not so sure about using stop leak though. I know it does more harm than good in A/C systems...

 

I have used that powder stop leak stuff in two different cars and it has worked in both instances. One had a leak at the thermostat housing and the other leaked from the water pump gasket.

 

tomorrow ill add the stop leak into the resovoir labeled engine coolant and then put water in it to fill the max line, and well go from there? thanks guys

 

Every time I've used stop leak I put it directly into the radiator. I would get a good degreaser/cleaner and soak underneath when the engine is cool and wash all debris off the bottom of the radiator. Start the truck and get it good and warm and watch to see if there is a leak. If your only going off that pic a rock may have dented a group of fins. Also keep in mind water/coolant needs to be check regularly. As it can get low through normal use. Also don't just fill the res to max, once the engine gets hot it will overflow. As alfons pointed out fluid will expand when hot and it needs room in that bottle to do so.
