I was told me heater core was bad in my 1992 Honda Accord lx 4 door. It will run a little hot in traffic but never goes to hot. Thermostat, raditor, and a couple of hoses have been changed along with the water pump. I guess my question is can you still get great heat if your heater core is leaking?

YES!

IF YOU CAN STAND THE SMELL

AND

IT'S PROBABLY NOT A REAL HEALTHY THING TO BREATHE THE STUFF

THE BEST AND POLITICALLY CORRECT THING TO DO IS TO REPLACE IT!

'COURSE, IF YOU LIKE ME AND PRETTY MUCH STARTED OUT WITH NOTHING AND STILL HAVE MOST OF IT LEFT

YOU MIGHT SLIDE BY, BY USING STOP LEAK IN YOUR RADIATOR (WHICH WILL CIRCULATE THRU YOUR CORE. (THE SILVER OR GOLD GLITTERY STUFF AT AN AUTO PARTS STORE)

I HAVE HAD GOOD LUCK WITH IT FOR THE RADIATOR AND HEATER CORE SMALL LEAKS.

PRETTY MUCH I HAVE HAD JEEP CJ-5s, THE RADIATORS HAVE LARGE VANES, IT WOULD BE HARD TO STOP THEM UP. SOME MIGHT ARGUE THAT YOU MIGHT STOP UP YOUR RADIATOR.

THE VAN AT WORK HAD A GOOD HOLE IN THE CORE, THE BIG GUYS JUST WON'T GIVE IN TO TEARING INTO IT (IT AIN'T MUCH OF A VAN) I COULDN'T BEAR SUCKING IN THAT SWEET FOG, YEP, IT GOT THE GLITTER TREATMENT TWO YEARS AGO AND IS STILL HOLDING TIGHT.

IF YOU DO DECIDE TO GO FOR IT, MAYBE ADD ONLY A 1/3 OF THE STUFF, SEE IF IT PLUGS YOUR HOLE TILL YOU CAN DO BETTER

Thank you that was helpful but I don't have a smell of course I've been adding water to it to try and find the leak I know if I leave the defrost on with the heat blowing my car runs very cool and also put in neutral to keep from pressure from building at stop lights. Would I have a better chance at finding it if I left the car in drive to build the pressure and push the water out?

IF THE LEAK IS DEFINITELY IN THE CORE, YOU ARE NOT GONNA SEE IT (UNLESS IT'S THE HOSE/ CORE CONNECTION THAT IS LEAKING, YOU MIGHT SEE IT)(THAT WOULD MAYBE BE FIXED BY TIGHTENING THE HOSES)

IF IT'S THE CORE, YOU ARE GONNA SEE WATER COMING OUT OF THE CONDENSATE DRAIN (WHERE THE A/C DRIPS WATER ON THE GROUND) MAYBE NOT A BUNCH, PARK ON CONCRETE AND CHECK FROM TIME TO TIME (BE AWARE THAT A/C AND ANY HEAT SETTING W/ DEFROST WILL TURN ON THE A/C COMPRESSOR AND PRODUCE WATER TOO)

JUST SO YOU KNOW THE WHOLE DEAL, A HEAD GASKET COULD CAUSE OVERHEATING. SHOPS AND SOME PARTS STORES OFFER A CHEMICAL TEST FOR COMBUSTION GASSES IN YOUR COOLANT, A SURE SIGN OF HEAD GASKET ISSUES

Ok I see no water coming out of the condenser line but it is a green Color fluid inside my car. That line did work in the summer but with all the rain and stuff we have here in Georgia I could have something small blocking it thank you again for your advice I've changed every other part of the cooling system but that (Heater core)

They want to charge 1,100 to fix it lol. The car isn't worth that

I wish mine would be so lucky. Everything is dead center of the fire wall surround by the vacuum system along with the EFI components. I'm 6'6" I do well just getting in and out lol. I think I'm going to bypass the heater all together just until I can find a new ride. Thank you again you have been very helpful

Nice jeep by the way!

DEPENDING ON MORE MODIFYING (FOR DEFROST)

MY SECONDARY HOMEMADE HEATER (FOR THOSE REALLY COLD DAYS IN A SOFT TOP)

AT MINIMUM-MAKES YOU REALLY TOASTY

IT COULD BE AN ALTERNATIVE, IF YOU ARE SORTA HANDY!

MY 1st ONE (NOW USED IN MY '46, WHEN I PUT ON THE HARDTOP) IS MADE OF WOOD

THE 2nd I CONSTRUCTED OUT OF SHEET METAL IN MY BUDDY'S HVAC DUCT WORK SHOP, IT'S IN THE '77. PRETTY MUCH THE SAME DESIGN. A CAREFULLY PICKED OUT FORD HEATER CORE MATCHED WITH A CHEVY BLOWER MOTOR AND SQUIRREL CAGE
