Thread: Heater Core Hose Restriction

So, I figured out where the heater core hoses are and one of them has some sort of clog/blockage in a certain section, because when I squeeze it, it feels much harder than other parts of the hose.

Should I flush the core or should I just replace the hoses.

If I flush the core, should I replace the hoses anyway? AND if I flush the core, do I flush through the heater hoses (disconnect from the intake) or flush from the firewall (skipping the hoses altogether)? Thanks!

You can pull off both of the hoses and flush it threw them. Go both ways. Then go ahead and replace them it will probably run ya like $10 for both.

replace the hoses and flush the core. I'm worried about you just saying it just feels hard. They way to check for a clog is to run the engine up to running temp and feel both hoses. If they're hot, then you're fine, if one's hot and one's cold, then they're both clogged.
