Hello fellow Blazer lovers.. I'm Jay from New York and I bought my 99 Blazer LS 4.3L 4WD 5 years ago.. It's been running great, but I recently began experiencing some overheating issues this winter..

I've always done minor repairs and maintenance (tires, oil change, cap/rotor), but recently I've been doing some pretty intermediate repairs (in my book) such as the alternator, water pump, thermostat and radiator..

I now have to replace ECT sensor, Mass Airflow Sensor, Throttle body, spark plugs and wires.. I've learned a LOT from this forum, YouTube and LOTS of reading.. I've bought Chilton's and Haynes manuals to assist me with repairs..

I've NEVER fixed a car before and working on my Blazer makes me LOVE it that much more.. I want to learn EVERYTHING about it and how it works.. I look forward to learning a lot more from everyone on this forum..
