I want to change my engine coolant and found this article:
It talks about installing the T-fitting in the heater-inlet hose that
runs from the firewall to the top of the engine.
I have one heater hose which runs on the driver side to the firewall and
one that runs on the passenger side. I suspect the one on the passenger
side to be the inlet hose that I need to install the T-fitting in. Am I
right with that? That one on the passenger side actually already has a
coupling in it, so it should be very easy to install the fitting. But
again, is that one the right hose?
Any other tips for changing the engine coolant are appreciated as well.
Thanks in advance.
