Customer Question

working on a 2000 f150 w/ no heat ... ome hose hot other cold

Hello, my name is***** one hose is hot and one cold that would mean the heater core is clogged. Sometimes disconnecting both of the hoses and then using a garden hose to flush out from both directions. If that doesn't help then heater core will need to be replaced. Let me know if you have more questions or if there is anything else I can do to help. Thanks.

heater core has already been replaced

I haven't been able to find the heater control vale

Have you bleed system good and verified coolant is making it to other hose? I do not believe there is heater control valve, what engine do you have?
Customer: replied 1 year ago.
4.2 v6... told you one hose hot the other cold
Expert:  Dan replied 1 year ago.

That could still mean poor coolant flow which would be different then now flow. have you pulled off cold side to see if coolant flows to it?

Expert:  Dan replied 1 year ago.

Or does heat get any better at higher engine rpm?

Customer: replied 1 year ago.
Auto Zone shows a listing for a HCV for my make/year/model/engine... when I pulled off the cold side w/o engine running nothing from hose and coolant spewed from the engine side... haven't tried higher RPM
Customer: replied 1 year ago.
how where do I get to the HCV
Expert:  Dan replied 1 year ago.

Try at higher RPM. I do not see a HCV in system, if it works at higher RPM that points toward weak water pump. Let me know, thanks.

why does the parts house show a listing if there isn't one?
Expert:  Dan replied 1 year ago.
Sometimes the listings are generic and apply to multiple vehicles so are wrong. Heater control valves are typically on vehicles that have rear heater such as a van where coolant flow needs to be controlled. Let me know if you have more questions, Thanks.

tomorrow I will blow compressed air through the hoses and re attach and see if that hellps
Expert:  Dan replied 1 year ago.

If heater core has been replaced it is sounding more like a water pump but nothing lost by trying the compressed air. Let me know how it turns out, thanks.

Customer: replied 1 year ago.
working on the premise that the heater core has been replaced... engine doesn't overheat why did not suspect waterpump...
Customer: replied 1 year ago.
let you know more tomorrow...
Expert:  Dan replied 1 year ago.

Sounds good, I'll talk to you then. Thanks.

Customer: replied 1 year ago.
cleaned heater core... problem fixed...
Expert:  Dan replied 1 year ago.

Good to hear, I'm surprised the new heater core would already need to be cleaned. Thanks for update, let me know if there is anything else I can do to help. Thanks.
