Where is my antifreeze leak coming from?
I have a 2000 silverado 5.3 V8, and between oil changes I have to put water in the overflow, because the coolant is going somewhere. I always check under the truck and there is never anything on the ground. While running I can almost always smell antifreeze in the engine compartment which is disconcerting. My dad said that It may just need a new cap. Does this sound right, is there a way to check for leaks when you can't see antifreeze going anywhere? Please someone help, the truck runs fine I just would like to fix this before it becomes a bigger deal than it is.
Thanks,
CC

Your heater core is probably leaking.
Run your defroster on a cold morning. If your windshield fogs up, that's the problem.

ok so when you park it tonight put a piece of card board box under the motor see if there is nething there in the morn...........
but some cars just use water..........
my brother had a cadilac that he had to put water in about every two weeks and there was no leak..
i have a 2000 buick that i have to put water in about every month atleast once so dont be worried there may not be anything wrong just using water but when you are running it see if you can smell antifreeze from the exaust if so you have a cracked head this could make it loose water well hope i helped..........

INTAKE MANIFOLD GASKET is leaking.... GM made a bad design from 1996 up into 2000 and all will leak and require replacement... and you will get another set just like the ones that are on there
Source(s): I have a 96 K-1500 5.7 Liter Vortec 350 and usually have to replace them about every 50,000 to 60,000 miles.... the gasket kit runs about $150.00 and then comes the labor cost unless you do it yourself and about 8hrs of time and very mechanically incline... you must remove the entire top side of the engine.... the intake sets between the engine heads on top - BerniLv 71 decade ago
Look for intake manifold gasket leak. We fix hundreds of these per year.

any garage can perform a pressure test on your whole cooling system, or you can go buy your own pressure test kit yourself at any auto parts stores.
good luck
