Ok so last saturday i jump on the interstate and hammer on the L. when i get to my destination i notice a coolant smell. so i look all over but find no leaks or even a wet spot. i drive the truck later that day and i smell it again. once again i look but can not find a leak anywhere. its a little low on coolant so i topped it off. when i topped it off i noticed a gasoline smell. it was faint so i just brushed it off. i havent noticed the coolant smell for a few days now so i decided to check the fluid level and its fine but i still poped the top on it. when i did it smelled strongly of gasoline. so i had a couple of people smell it to make sure i am not crazy. we all agree that it smells like gas. anyone ever heard of gas getting into the coolant system ?

 

head gasket leak

Check rear pass side head gasket for oil and coolant residue

 

Yep.

 

You really got to watch out for that wet spot. I avoid it like the plague.
