Change hoses are 75k?

hay i need a 2nd opinion on my tacoma 2010 i have 75000 the coolant and hoses are original, coolant needs to be changed should i change the hoses too or leave them
and can you tell me where to find the drain cock on the block.

 

I changed the hoses and thermostat on my 2010 while I was doing a coolant flush at 130K or so. They looked good. If you have 75K on them they are probably fine. There is on drain drivers side bottom of radiator and two block drains, one on passenger side and on on drivers side. Access both through the front wheel wells.

Attached are factory instructions for coolant change.

 

I just recently did this. I didn't replace the hoses because they looked fine, but I did do the thermostat since it's cheap and easy. Here's what the block plugs look like. Passenger side is easy, you just need a long extension and a 10mm.

Drivers side is a little trickier. I took off the wheel/tire to make it easier, and you need a U joint to get it lined up.




Expand this quote below for full details. It helped me out.

 

For the block drains it might be a good idea to shoot some PB Blaster on them every day for a few days before you do the job. Mine were damn tight and I was reluctant to put a ton of muscle into it since I didn’t want to break them.

Lots of opinions about how to drain the block on the drivers side of a 4.0L V6.

 

If you pull the rubber or plastic-like covers in the wheel wells, you should be able to visually spot the drain valves. You can also turn the valves from there; although the driver-side is a little trickier and you will need a long extension. If your truck is not raised, you may need to lift up the front end about two inches. Ditto on the hoses, they should last 150K, your next coolant flush. I replaced mine at 100K and they were in near perfect condition. I've kept them as backups. Also replaced the belt and thermostat. BTW, I'm an advocate, and practitioner, of universal coolants - SuperTech, Prestone, etc.. Just read the manufacturer's directions and you will not go wrong. No need to purchase pricey red Toyota, or equivalent, coolants.

 

150k on mine, still look and feel fine.

 

Worked for toyota for 4 years have yet to see a toyota come in with a bad radiator hose.

 

I've gone 20+ years on radiator and heater hoses. The last vehicle I had with a failed hose developed an aneurysm on the upper radiator hose at about 27 years old and 180K miles.

 

Good metaphor for a hose bulge and you spelled aneurysm right. Kudos!

 

How about original serpentine belts?

 

Honestly rarely see failure without a warning, since they nixed timing belts changing of serp belt as general maintenance seems to have gone away.

 

I changed my Serpentine belt at 130k. It looked so good, I kept it as a spare. New Bando brand belt was under $20.

 

Just changed my belt at 95k had a nice split in it
