I'm going to be installing a coolant filter on my truck and had a few questions. Here is a pic of the setup I intend on using.
The filter head is a Napa 4019. The line from water pump (return line) will run into the top tee and out to the heater core. The line from the block (feed line) will run into the front tee at the 90degree fitting and into the heater core. As you can see in the pic, I plan on placing a ball valve in the feed line after the filter but before the heater core. My thought is that I can use this to shutoff flow to my heater core in the summer, and that it would be a little simpler (more reliable?) than the ranger vacuum controlled bypass. Is it okay to block this line and not bypass it? The filter will act as a bypass to some degree, but will it cause too much flow through the filter since it is intended to be a bypass filter (I read that restrictive)? Is there any expectation that flow through the heater core circuit is unimpeded, or does engine coolant circulation not care if the core is blocked off?
Also, I get water in my cab where the heater core comes out at the firewall. What are people using to seal this up? Is there a foam piece readily available?
Thanks for the help.
