Yes, Victek, the Elantra is one of THE simplest vehicles to change the radiator fluid I have ever seen. The "petcock" is a red plastic bolt at the bottom of the radiator. Once you look, it is hard to miss.
Make sure the car is cold, open up the radiator cap before you open it, and let it pour. While it is draining, remove the coolant recovery bottle, drain, clean, replace and refill it.
If only other vehicles were that easy.
If the pictures don't show, you have to download the viewer. Look at the Site Requirements for the viewer available for free from Adobe. You also need Internet Explorer
Yes, the SVG viewer appears to install successfully and I am using internet explorer, but the graphics still don't display on hmaservice.com. I'm not sure what to do next. Meanwhile regarding the Elantra, do you know how to drain the radiator?
Bottom of radiator, driver side, really dark there, get a flashlight, use big phillips head screwdriver.
Are we talking about a large red plastic Phillips screw head that flush with it's socket? (It looks to be in the right position)
Regarding the issue of the SVG viewer and the HMAservice.com I have installed the viewer on three computers so far - one with Vista and the other two with XP SP2 - and the graphics will not display properly on any of them. If someone has a clue about how to fix this please speak up.
