I have a very nice & great running 02' Blazer ZR2 but it's running a few deg warmer than I'd like here in SE TX. She's been running 210° w/ a 195° thermostat & climbing on hot days, when she was running about 200° in the summer. I just use a Crescent Wrench & a tap of a Hammer to pop that clutch fan loose & 2 taps to tighten it. Pops loose everytime. Its an easy 1hr project to replace the water pump on a 4.3 I'm doing mine tomorrow even though my current pump isn't leaking & I show flow in radiator after the thermostat opens. However, I hate it when my temp runs above 210°. Guess im a bit OCD & I love to tinker or Shade Tree. I've done the upper, lower coolant hoses, flushed twice, new thermostat, coolant, added Water Wetter that doesn't work, a new Hayden Severe Duty Clutch Fan, temp sensor, belt, tensioner, idler pulley, you name it. I have a heavy homemade 5x9 utility trailer that put some strain on my coolant system. I'm sure the engine is fine at 220° but I'm not taking chances. Nice info..
Perfectly explained and filmed for this kind of content. I watch quite a bit of “how to” and a lot of the time its poorly filmed and missing the important steps.
It was the cheap autozone brand, only store locally that had one at the time, the back cover gasket kept leaking and i think it was already leaking from the weep hole
Excellent job explaining and filming! Thanks!!
Thank you so much...your vid saved me $200 in labor cost by doing it myself.

If it does it with the AC on only it's the condenser
Thank you so much for this step by step guide. Made this really easy.

Those four bolts on the fan. I just jam a wench on it,. the end.
Great video. No need for torque wrench? My Chilton's has torque specs. I don't have a torque wrench, so this helps me greatly. Thank you!
Only thing I've ever torqued is the important stuff like main caps and rod bearing caps
@@theman9764 Thank you!
@@theman9764 Is there anything I can put on barbs to get hoses on easier? I had a helluva time getting lower radiator and "U" shaped hose off.....
Great video! I have to do this in a day or two to my '97. What brand water pump was it that you had to replace in 4 months?

Is this the same process for a 1988 Chevy s10 blazer v6?
Should be very similar, as long as it's a 4.3, couldn't tell ya if it's the 2.8
Thank you.
