Heater core link
The '90 blew out it's heater core today. Someone posted an article showing
how to remove and replace the core without pulling the entire dash. I sure would appreciate someone re-posting that link. Thanks, Ken |

Thanks, Roald.
One of my daughters was driving the Miata yesterday when the core gave out. She called and said the floor was full of "green stuff". Since this happened only a couple of miles from home, I decided to refill the radiator and drive until it got hot. Two refills later, I was home. Today I need to pull the seats and carpeting out and (of course) the heater core. For anyone who finds themselves in the situation of doing this, be careful of the hot water that leaks on your foot. I realize that I could have bypassed the heater core in the engine compartment, but I was sort of time pressured and just needed to get it done.

I have a 97M that is vaporizing antifreeze through the vents. I had it
checked and its the core. I bought a used one and had it tested and will have it replaced soon. My question is should I have my timing belt done at the same time? I did not think so, but I am not that familiar with the repairs for either. I have all the parts for the belt and wanted to get it done soon. Thanks, Lorne |

One thing at a time:
1. Leaking heater core - needs to be done now. Trust me, you don't want it to get worse. 2. Timing belt - How many miles? If it's 60K+, then it's not a bad idea to do it. Suggest you provide a water pump at the same time. The car will be out of service for a little while. Since you are depending on someone else to do it, probably best to get it all over in one shot. There is no relationship to these two jobs other than draining the antifreeze. Ken "VAdude" > wrote in message lkaboutautos.com... > I have a 97M that is vaporizing antifreeze through the vents.
