Hi all,

Just asking becuase I see so many posts about them leaking ect..

I still have the original and am thinking of preventative measures... Anyone have an opinion on this?


Cheers,
Felix

 

Still have my original core, 92 Camaro

 

10 years, 103,000 miles for my 83 Z28

 

My fist one started leaking in May of 1992, or about six years and 18,000 miles after the car was built. The second failure was in June of 1995 - almost nine years to the day when the car was assembled, and at 34,988 miles. The last one leaked in March of 1999 at 44,077 miles. At that point, I completely flushed the system, ran clear water, flushed again, and installed DexCool mixture. At 48,190 miles, I'm either due for another heater core, or the DexCool is keeping the corrosion down to a minimum. I'm being optomistic (but still crossaing my fingers).

I'm fairly certain the long periods of idle storage were taking their toll on the cooling system. Low pH of the aging coolant was probably eating up cores as they sat there. I'm planning to go the full five years between coolant changes with the DexCool, playing the rolè of Guinea Pig. I'll let you know...

 

well ive had good experience with heater cores i replaced the one in my firebird in 95 and its still good the camaro i dont know ill have to see watch thats whats gonna go wrong next lol

 

Still running on my original core, car has 249,000+ miles on it. I bought the car at 65,000 miles in Jan of 1994, so I guess it's possible that someone changed it on me before I bought the car?

Like you, I'm changing it this summer before it blows out on me.

 

16 years, 140.000 miles before mine went.

 

14 years, 130k

 

I still have the original one. 21 years old and over 260K miles.

 

i lost mine in '98 or '99, still havent replaced it. i just rerouted the hoses.
i live in AZ, no need for heater here. lol

 

This is the type of question that causes bad luck

I refuse to answer for fear mine will begin leaking tomorrow.

 

My original core lasted 6 years. Replaced every two years since.

My '88 GTA has the original in it, and it has 114000 miles...
