Re: YJ heater question prt. II
Coolant is clean, recently flushed system.
The 185 heats ok.... thinking that a 195 would keep me warmer?
Not sure about the heater control valve (93 YJ) but I know what they look
like, I had to replace the wife's XJ hcv
I figure I will try redirecting (or capping) the passenger side heat duct
for while I'm driving alone.
thanks
