temp gauge was good which is what confused me. Maybe I don't have the proper mixture. I'm going to check that. It warmed up later and worked fine when the temps got higher.well its a chilly 24F here this morning, The SR20 is slower than the Ga16 to warm up but was fully up to temp about 6 miles, or half way to work for me.
What did your temp gauge say ?
If it reads low then you may have a sticky thermostat, or it may open early.
The SR20 was like that, never got fully up to Temp in 11 miles. Changing the thermostat fixed it although the original i took out was closed. ie it looked OK, but i didn't test it, just tossed it.
Yes then the most likely is reduced flow.
Check the hoses to make sure the heater supply is not restricted.
most cars have a heater shut off valve, so when the A/C runs the hot water is off.
Maybe this is not fully open ?
I don't even know for sure the B14 has one of these?
I think you have worked on the heater and A/c unit more than anyone on here ( at least in recent history.)
that sounds fishy. Same reason I always do the work myself. I simply added some coolant to fix the issue. Was a bit low which usually will cause heating issues. Sounds to me like to go stiffed big time. Even though it is possible. I'll probably change my thermostat over the summer when I do a flush again. If the heater was really bad, I think your bill would have been like $400 and not $200 since the heater core alone is like $161i have the same problem so i took it to the shop cuz i dont want to deal with it i just got a call back from the shop and they told me that my thermostat was stuck open and i have a clog in my heater core and i guess its cracked from the clog. just got the bill $200. :wtf::
in the winter i just use a small piece of card board in front of the rad. not fully blocking it just to dampen the air flow but i have a hard body and the fan is always running i do it every winter cause up in n. idaho it gets efn cold
