After doing some reading and replacing the leaking heater core anyway I installed a coolant filter with DCA additive. Went pretty well. No leaks. Filter is on a bypass circuit and there is a shutoff on the 5/8" heater hose so in the summer I can shut off the heater circuit and keep the filter circuit in the loop. Also added a filter to the fuel tank vent at the top of the engine air intake. No picture as it was dark, will add some soon. Was having an issue with loosing prime and when I went to remove the fuel fill cap tank was under some pretty good vacuum. First thing I looked at was the vent and it was plugged solid with some kind of mud dauber or something. It was plugged solid. Looked there first as it was plugged when I first got the truck running. Truck now has it's pep back and hopefully the vent filter will keep out the bugs and there homes.
I would interested in any info you might be able to provide with regards to using a coolant filter with or without the DCA additive. I have started researching this issue because I will be adding a coolant filter to my truck soon.
Am I correct in assuming that the bypass valve was to reduce heat in the cab during the summer?
Can you provide a simple diagram of the bypass plumbing?
Thanks,
Tom
