Does anyone here have a 2009 Hyundai Accent? I have had it for 5 weeks now and the
heat is lukewarm when heating up the car for 20 min in the driveway.  It does not
melt the ice or snow.  When I actually drive the car after warming up the heat is
very hot within a couple of minutes.  I am told this is supposedly normal.  After 40
years of owning cars I have to start scraping my car in morning because the heat
is hot only when being driven!!  Please, if there is anyone out there who has one,
I really would appreciate your letting me know if yours is the same.  

if you read the post i just answered  about the honda no heat...

the heater core is the long way around for the engine coolant..

do to the design.. you may have to rev the engine to get some heat...      

you might also try it with the fan on low...

mercedes actually had an electric water pump in the heater hose to create enough flow for the heater core.... kept its owners comfy..  

some cars a few years ago... had a problem..  too much heat directly at the base of the windshield..  cracked a lot of windshields....

my thoughts on running the fan on low...   faster air flow through the heater core takes more heat out of the coolant..  with the engine running at idle...  the coolant is not being circulated fast enough through the heater core to produce enough heat with the fan on high...


i have a question... its probably too cold to apply it.. but i have always wondered.. if rain x would make it easier to scrape the ice or prevent it from sticking...    it might be worth a try on the side and rear windows were there are no wipers...


here is a link... you must copy and paste it in a new window...  of a electric water pump for the heater

the application i looked it up for...   1989 mercedes benz.. 190E 2.6...   they are 70 to 90 bucks at some parts stores... i looked it up at bmaparts.com      

if  you decide on this.. be sure that you figure out which way the coolant flows... so you don't have the pump trying to work against the flow...    you can figure out possibly a relay to control the pump...    

if you need more info.. just post... i will probably see it..  

Thank You Wayne for the suggestions you made about reving the engine or putting it on
low fan.  All of that makes sense to me and I will try it tomorrow. I just got my
car back from the dealer and of course all they did was check the temperatures with
their gauges.  My son who has worked on cars since he was 16 suggested that they
flush the system in case anything was blocking some vent or dohickeys?  He now is
in Louisiana working on the B-52 Bombers in the Air Force so he can't help me here.
Our temp. right now in CT is 16 degrees and dropping.  Tomorrow morning will be a
good time to try your suggestions.  Thank you so much for your reply.  I'm sorry I
didn't see the first one.  I will let you know what happens when I start it tomorrow.  

i hope it helps... at 16 and dropping.. you really need to let it warm up a while before you bring the RPM's up too high..     1500 to 2000 rpm will probably do it..

be sure to complain to the manufacturer about it...  in writing... with copies going to consumer reports..  

It was 12 degrees this morning and there was frost on all the windows.  I revved
it up a couple of times and let it run for about 20 minutes.  When I got in the car
was warmer than before and all the windows were clear of the frost.  At least I didn't
have to do any scraping.  It sounds like a good idea to write to the manufacturer,
thank you for that suggestion.  Thank you again for your help.
