I know this topic had to be discussed in earlier forums, but my concentration is now on the heater control valve located on the eng firewall. I will list the series of events and would like to know if other Lex-heads had similar problems.
1. First of all, does the heater cont. valve ever get clogged up with crud? I've noticed some crud buildup around the inlet hose connection, my question is how does this happen? Is there enough crud in the cooling sys. that would cause this?
2. I first noticed the problem when the heat would turn cool whenever the car was idling, and would kick in again when the car started moving with the higher rpms. Which means if the hcv was clogging, the coolant needed higher rpms to be forced thru the hcv. Does this make any sense?
3. Can the heater contol valve be cleaned?
4. Should I run some radiator cleaner through the sys, would this help? Or should I simply replace the hcv?
Thanks much if anyone cares to share their experience with this issue.
Cheers,
