Tip & How-To about Chevrolet Silverado 1500

Small coolant leak

This is a little easy diy'er for the everyday joe.If you have noticed a small coolant leak coming from your motor area, not a pouring leak but more of a drip,and you don't feel like paying a repair bill of $400, then go to your local neighborhood parts store and purchase a bottle of radiator/coolant stop leak.The best brand I've found is called Bar's Leak, it actually seals up most small coolant leaks within the day.All you do is add this to the coolant in the radiator.I hope this tip helps!!!

loosing coolant


the test is easy
it uses the magic of the system has 12 to 14PSI pressure all the time.
hot. so park it get it hot. to 180F (old thermostats fail, they are #1 failure ,so why would you discount that?????)
ok its really hot , my pryo gun shows 180F ,ok real hot is true. no bs.
so now look for leaks.
if you see none
and the passenger toes are dry (heater core drips)
then there are on external leaks,
if true that, then its INTERNAL LEAKS!

head gasket is failing or the A/T or engine oil pan is full of AF.
are you running 50%^ AF all the time, ?????

everywhere you drive do you look after parking, for ground leaks.?
as you leave car and when you come back.
you must. or miss the boat.

If nothing is leaking externally from engine area, then I'd have my exhaust analyzed for coolant coming out the exhaust. Bad intake gasket or head gasket usually indicated by coolant out the exhaust pipe.

im getting antifreeze fumes from the engine area but no leaks.


I would pressure test your cooling system which would cause any otherwise unnoticeable pinhole leaks to spray a small mist of coolant if there was in fact a leak present. I had a similar problem with my wife's dodge caravan, I kept smelling coolant after she drove the vehicle for long periods and I checked the entire cooling system and inside vehicle for a potential heater core rupture and nothing was ever seen and coolant level always remained full. A couple days later I noticed the same thing and allowed the vehicle to cool down, I then pressure tested it at 16 lbs, I did not notice a drop in the guage but then I noticed 1 small drop of coolant coming from the water neck where I had replaced the thermostat several months back. I torqued the bolts down a little more rinsed off the area and have not noticed the smell anymore. That 1 drop of coolant would immediately evaporate once it hit the block but the smell was strong enough to get my attention and to figure out what was going on
