Okay, well i have been through a few EF's And a lot of my friends have/had EF's And I noticed my heater doesn't blow hot like EG,EK, and DC's is this because my car is old, or my heater core is old? If so, can i just swap out the heater core from one of the above cars?

TIA

 

If you have an EF yes. Nice title.

 

My 1991 civic blows hotter than my 2003 civic

Any given fluid in the 1991 at any given time is usually newer than the 2003, that might have something to do with it....

Try a coolant flush.

 

people come up with the wierdest titles now a days

 

a ef heater should almost blow hotter than newer cars cause they have a electric heater.just flush out your system,did mine the other day and it get soo hot it burns my face! =]

 

Word

 

wait waht flush what out and what about this electic heater?

 

yeah just do a flush..im stationd in alaska rite now and my 91 civic heater blows hotter than my boys new 2005 civic....

 

just go buy a hanes manual and it will cover everything.=]

 

so a flush would make that much of a difference. its only been flushed with water, would you guys recommend a radiator flush fluid like prestone super flush

thanks for all of the replys

 

My **** blows hot enough for me n the car behind me lol..........flush it!!

 

i used a garden hose

 

Have you checked the cable under the heater core? Check the faq, there's a good link on what to look for under "no heat" or something.

 

i cant find in the faq

 

you really need to actually take the time and browse correctly through the FAQ's
