Holy exploding heater cores, Batman!

5 years 5 months ago #5175 by James Howard
While driving the RRC on I-10 between Phoenix and Tucson, there was a "Pop!" followed by a huge cloud of mist filling the windscreen. Fortunately we were the the right lane and were on the wide and straight part near Red Rock. I memorized the road and slowed gently while edging off to the right. Ignoring the coolant pouring on to her feet, Kelly quickly rolled the windows down which allowed the mist to dissipate, and we were able to stop way off the shoulder.

I bypassed the heater, and then we poured all of our water into the engine. We had about 1.5 gallons and it was enough to keep the temperature gauge reading normal, but not enough to get the low coolant light to stay off.

Replacing the heater core is one of those jobs I am not looking forward to, especially since I just had the dash half apart to replace the air conditioner hoses. I think I will wait until November to do it.

Sorry to hear about your coolant explosion!

The heater core is not a fun job, either.

James,

What year is your RRC? I have an '88 that I am restoring and Chad Manz suggested that I replace my heater core while it is disassembled. However, when I called Rovers North, they said they could no longer get the heater core for my vehicle year.

I am curious what year your vehicle is and if you have been able to find a replacement.

Nice job on having the extra water handy!

Mark

Since it is incredibly hot right now I have put it on the back burner and have not bothered to research a source. Sorry.

Ours is a 1992. I am not sure if it is significantly different than the 88.

The last one of these I replaced (in our 1989 RR) the core was aluminum with plastic endcaps and pipes. The plastic was what failed. I was going to research if an all aluminum one was available. I do know to replace one you have to tear the dash almost completely apart, so if yours is in that state I would definitely replace it.

Nooo! I thought I'd repressed that memory, but that picture brings back all the horror! The horror... the horror...
