I need a more serious heater core flush suggestion
heat has been a problem since i just bought my truck (94 s10 pickup 4cyl), replaced the thermostat and then deduced that my heater core was obviously quite clogged (in-flow is very hot, out-flow was cold).
so i took it to a self serve car wash, and stuck the nozzle to the in-flow pipe and now the in-flow is very hot, out-flow is only luke-warm, making the inside heat work maybe 40-50% of its whole power.
the truck i bought, had been sitting for about a year so i figure the is alot of buildup of gunk in the heater core, so is there anything else anyone can suggest that i throw at it (or in it more-less) to clean this thing out?
Id prefer a method that would be quick, but all suggestions are welcome (and i live in an apartment with no water-hose)
maybe i should go back and put the power-washer through the out-flow tube of the core and let it flow out the other in-flow tube too? or will the pressure maybe hurt the core?
