Coolant leak
Asked by Buzz4251 Mar 02, 2017 at 02:17 PM about the 2003 Volkswagen Passat GLS 1.8T
Question type: Maintenance & Repair
I have a 2003 Volkswagen Passat that I believe the
heater core leaks but while I was looking at the
hoses I noticed a lot of rust and corrosion at the
mounting position of the hoses could the hoses be
leaking from rot I mean I do smell the coolant
inside of the car I'm just trying to make a easier fix
rather than an 8 hour heater core job

get autozone to pressure test the system...may be a small leak . if small, stop leak usually does the trick make sure to follow directions

don't use stop leak ,it's made to plug small holes and thats what your coolant system is . The connections are corroded because there getting wet from coolant that could be coming from nearby , definitely somewhere ,, you need to take care of the leak thats how you fix it .,
Stop leak has been used for a hundred years... like I said follow the directions
if its your heater core and most likely it is since you smell antifreeze while driving then they are a total pain in the butt to change put the powdered aluminum in if you have an aluminum radiator or the cooper colored stuff if you have a brass radiator and drive on !
I have 2005 VW passat 1.8t I have read all the questions and answers about why and why not to use "stop leak" out of my personal previous experience I Wil not use it I had a 2002 Chrysler PT Cruiser and it had a small leak that I couldn't find so after read anf ollow all the directions I put "stop leak" I drove exactly 35km before the engine overheated, so I Wil not use it on this car, but my question is a budget one, can I bypass the heater core pipes and will it cause problems for me other than losing the cabin heater? I live in the low veld I don't really need the heater and for as long as I had the cars I never switched it on.
