well this is the 4th one i have installed. this one lasted 2 days. what is going on? why is the heater core always going bad. i replaced it this time with an all metal one and it didnt last 2 days. maybe its time to get rid of this damn thing.
Really bad luck or parts? or maybe debris in cooling system?
idk what can i do to fix this issue?
put a chevy one on the dash lol bummer tho weird
4 parts i cant see it being bad luck has to be an issue somewhere. i dont see anything in the coolant.
could it be over pressurizing the system? i put a new rad cap on it last time i put a heater core in it
but why the heater core y not the radiator?
hows the water pump circulating? ya got me ya cant put the hoses in the wrong spot right?
nope only thing i can do is switch the hoses on the heater core so it would flow top to bottom or the other way around. i have been hooking them up bottom inlet top outlet. thats right isnt it? water pump is new as of june when we bought it i put a new one on there.
where do they leak from when ya took it back out??
idk i have the old one in the garage. it has plastic tanks on it and i cant see the leak in it. but the all metal one i just put in there 2 days ago is leaking the worst of them all. it was pouring out this time. i wont know where that one is leaking till i get the replacement on in there but I dont want to put that in until i figure out why it keeps leaking. sick of taking the dash out all the time.
its gotta be somethin small thats getting missed like a peice not lined up right and pinching it or something like that
well this time it wasnt the heater core. the heater hoses were not tight on the heater core. it had the spring clamps and they were not strong enough. got it all back together with hose clamps and no leaks. cross your fingers the heater core doesnt leak now lol. thanks guys.
what truck are u installing a heater core in?
Kia sportage. There a piece of crap too won't ever buy another one.
Put on a new rad cap and flush the cooling system. Good call on ditchin those clamps, the spring ones suck. Is the heater box completely free of debris? Good luck on this core, i feel for ya those little foreign cars can be a PAIN!!!
