HAS ANYONE REPLACED THERE OWN HEATER CORE ON A '98 BLAZER? HOW MUCH OF A PAIN IS IT? AND DO YOU HAVE TO RECHARGE YOUR A/C AFTERWARD? THANKS, RON

 

Welcome Ron, I've done PLENTY of these, it's not hard at all to me..in fact it's my favorite job, but MANY on this forum will tell you otherwise. You do have to remove the entire dash, andyou're supposed to remove the right front fender too, but you don't have to. The job paysabout 11 hours to do if that gives you any kind of idea. You DO NOT have to recover,evacuate and recharge the A/C. If you decide to tackle it post-up and we'll get ya pointed in the right direction. What's your concern? no heat? or leaking? If it's no heat...try back-flushing the core first it often restores heater performance at least for a while...if it's leaking...you'll have to replace it of course.

 

I'M GETTING A STRONG ANTIFREEZE ODOR IN THE CAB AND IT'S FOGGING UP MY WINDSHIELD. NO WET CARPET OR PUDDLES YET. IT'S BEEN SWITCHED FROM DEXCOOL TO REGULAR ANTIFREEZE. IS THIS GOOD OR BAD?

 

You'll find mixed opinions on the dex-cool, I myself have no problem with it. I still have it in mine. It sounds like you do have a heater core leak though.

 

THANX FOR THE INFO. I GOT THE BLAZER ON FEB.5TH FROM A LOCAL DEALER WHO SAID HE GOT IT FROM AUCTION, SO I'M NOT SURPRIZED IT NEEDS SOMETHING THIS SOON. I NOTICED WHEN I BOUGHT IT THAT IT LOOKED LIKE SOME STOP LEAK WAS IN THE RADIATOR, SO I'M SURE IT WAS PRE-EXISTING. OH WELL, IT'S MY 4TH 4.3, I LOVE THOSE MOTORS, AND THIS BLAZER. INSPITE OF THE REPAIR, IT'S STILL CHEAPER THAN CAR PAYMENTS!!!!!!!!!!!
