Automotive maintenace question
My 2010 Toyota Tacoma is approaching 100K miles and I will doing all of the factory recommended maintenance myself, to include flushing the radiator and replacing the coolant.
What's your opinion on replacing the radiator and heater hoses at this time? They are still soft and pliable and there are no leaks.

If ain't broke don't fix it. 0 -
They ever been changed out? I'd buy the hoses. When you're flushing out the system with the lower hose off make the call. Look for odd rub marks on the heater hoses. I'd seen flat spots and metal to rubber marks that was kind a concerning. Oh and those "T" connectors with the crimp connectors that fail.
I got a overflow "T" to heater core that I have to keep my eye on. What is it with GM and it's hoses?0 -
I would let the hoses alone and replace the brake fluid. Brake fluid is hygroscopic. Pay attention to DOT 3 or 4 too. It's important. 0 -
I doubt they still used DOT 3 that late, most likely it's DOT 4 which is silicone based and not hydroscopic. 0 -
don't touch the radiator. Inspect heater hoses for signs of thermal breakdown, replace them as needed. 0 -
Not a need. Today's rubber is much more resilient.
Also, ALL brake fluids are hydroscopic. I would absolutely recommend a brake fluid flush. DOT 3/4 has nothing to do with anything other than boiling points and most fluids are marketed Dot 3 or 4. Dot 5.1 is also Glycol based and can typically be mixed with other glycol fluids.
Dot 5 is the one you do not want to mix.0 -
I would be more inclined to replace the thermostat than the heater hoses, but definatley flush the motor and radiator..... if it is rusty looking it may be to late as head gaskets will be in the near future.. 0 -
I've never had a coolant hose get hard, Quite the opposite in fact. They get spongy when the rubber starts to break down and separate from the nylon reinforcement cord. 0 -
Just drive it and don't spend money on things that will typically last 15-20 years on today's cars. 0 -

My recommendation is to make sure you do the timing belt and water pump replacement. 0 -
my 2K tacoma has a timing belt and 230K miles..works fine ...i got one of those nearly $5K estimated repair costs on our 2010 honda pilot at the 100K mile mark ...mostly a golden calf money maker for the dealership ....no wonder they can take $8=9=10K off the price to sell you one if if comes back thru the shop at those prices on a regular basis...scares little old ladies running for their checkbook 0 -
Timing belt and water pump should only cost around $2200 depending on dealership maybe cheaper at an independent garage. The nice thing is that's about the only major maintenance you should have to do with a taco. 0 -
Is replacing the hoses part of the 'factory recommended maintenance'?
There's your answer.0 -
Holy crap,5 grand to replace the timing belt and water pump? 0 -
time to replace the yoda[:o)] 0 -
What engine? Pretty sure Toyota V6 uses timing chain. At least that's what my 2005 4 runner has. I don't buy vehicles with timing g belts. 0 -

Yeah, since the parts are around $200 for the pump and belt.0 -

I have a 2006 Tacoma 4 cylinder model. At 100k miles I replaced the spark plugs, the cabin air filter, cleaned out the engine air filter (k&n), greased the U-joints and other chassis points.
I drained the radiator and block of coolant, closed them, filled with fresh coolant, and checked (not replaced mine you) the condition of my hoses, the belt, freewheeled the Pullies and wheels to listen to the bearings, they all checked good. I also replaced the brake fluid when I replaced my front brake pads for the second time. So that was good and replaced my power steering fluid.
I think that's pretty much it. Still on the original water pump and all my other accessories except the AC compressor. Your Tacoma will outlast nearly every vehicle out there so don't worry.
At 150k I replaced the diff, transfer case, and transmission gear oils.
There is no reason to replace a radiator on a Tacoma until broken.0 -

Small note, but for future reference, the word is hygroscopic.0 -
Does it have an automatic transmission? 0 -
Some Geezer thoughts:
I've NEVER changed brake fluid unless there was a massive blowout of a brake line(any brake line failure was due to EXTERNAL corrosion or damage BTW).
Over the years, I've had more problems with coolant hoses/thermostats than any other age related(vs mileage) component(s) failures. Most often those failures were catastrophic and had the potential to cause serious engine damage or result in being stranded at whatever point the failure occurred.
Belt(s) and hoses should be changed during any major cooling system repair, maintenance project.
I just bought a 14 year old pickup with 74K miles on it. I've run it 6K w/o any problems but will darned sure change serpentine belt, radiator hoses, thermostat, coolant and possibly heater hoses before the New Mexico elk hunt. One to two hundred $$ for parts (labor is free when you're retired)should preclude any possibility of a ruined trip because of a cooling system problem and I won't have to worry about such issues for several years in the future.0 -

And the can I just bought said it was 3 + 4 approved.
Replaced the brake fluid on the 07. It was due. I've seen what happen when you don't.0 -
Thank you all for your input. I decided to replace the radiator hoses and thermostat. I will also change out the brake (Dot 3 is needed) and power steering fluids.
Someone asked about the transmission. It is a 5 speed maunual. The engine is a 2.7L 4 cyl. I drained and filled the front & rear differentials, transmission and transfer case yesterday and installed a pair of auxillary LED driving lights.
Still waffling on replacing the water pump and heater hoses. I'll consult my nephew who owns an independant auto repair shop.
As I get older, the more I dread having a breakdown at the most inopportune time in a less accessible place. Since I am semi-retired and do the work myself, the only cost is for parts.0 -
"Still waffling on replacing the water pump"
Water pumps often announce their demise well in advance the total failure IF you pay attention. A frequent whiff of coolant, drips/puddles under the front center of the vehicle, or an additional bit of whine at idle.0 -
I think the Toyota 2.7 engine has a timing chain instead of a belt.There is no recommended service on chains.My Frontier has almost 500,000 miles chain it came with new. 0 -
I've never heard of anybody changing a water pump as preventative maintenance, except on engines with timing belts. One of the things that separates some of the brands from Japan from others, is the quality of the components they use. The OEM Toyota part may be good for 500,000 miles, while the aftermarket parts probably isn't. 0 -

Yep. HD chinese wheel bearings lasted 8k in the 07. Kawasaki Japanese wheel bearings lasted 40K on the Kawasaki Concours.
Guess who's HD has Kawasaki wheel bearings now?
PS if you can wiggle the fan connected to water pump -it's most likely replacement time.0 -

..it has a timing chain...the maintenance manual calls for it to be mic'd at 100k. Mine checked within limits as if it was a brand new chain....at 150k miles#128514;0 -
