Before last winter, I flushed/ backflushed my heater core, twice, just using hose water and pressure, and was able to significantly improve the heat levels exiting the vents, but not to previous levels. Not all that much crud was in the bucket catching the exhaust, and not much improvement was expected so i was pleasantly surprised when the thermocouple registered 25f more degrees at the vents.
In this flush process I had to slightly shorten one of the hoses, a red /all purpose fluid Napa hose replaced in distant past.
This hose is now bothersome, and I am going to replace it, and the rest of the heater hoses that are showing their significant age.
No better time to flush the heater core again, but wonder about using something to perhaps better dissolve/loosen anything occluding the tubes of the heater core. Rest of the cooling system is healthy enough, I drop and replace 2 gallons of the total 4 gallon cooling system capacity, with regular green coolant once a year(ish)
That time is soon, and If I can get more heat from the heater core come this winter, it would be appreciated.
I will check the blend door's seal at some later date.
Any product/method advice?
I have been using a low dosage ( 1 tab) of the ginger root bars leak tabs to prevent the all aluminum radiator from weeping where tubes meet bottom tank, since 2011.
I will continue to do so once I get system refilled after replacing heater hoses.
