Job Difficulty	Easy to Moderate DIY
Maintenance Tips	Use correct coolant, replace clamps when weak, keep oil leaks off rubber hoses, and pressure-test the system after service.

This is the correct BOTTOM radiator hose from Dayco used in a 1998 Ford Explorer V6 (X) engine. This molded/curved radiator hose fits perfectly without trimming. I replaced all heater hoses along with both top and bottom radiator hoses. I tightened each hose using Breeze stainless steel clamps. After putting everything back together when it was time to turn the engine over and check for leaks, presto, NO LEAKS! I have used Dayco products for many years without ever a problem. Thank You AutoPartsWAY for selling great named brand products and service coupled with FREE delivery right to my door, arriving safe and secure.

Same shape as the OEM hose. Does not come with internal spring so make sure you take out the old one. I just turned it like a screw to remove & install

My 1998 Chevy Tahoe that requires a hose specifically made for that vehicle. It starts out going toward the rear of the car, then toward the driver side, then finally toward the front of the car and the radiator. I looked at the several choices available on AutoPartsWAY, where I do almost all my shopping to save gas and time, and this one stood out as looking like it would be the best. When I received it, it looked awesome. When my mechanic installed it he said it fit perfectly and had more protection than the hoses from ACDelco and other manufacturers.

Better made than the seemingly OEM one it is replacing. Have not installed it yet but it is clearly more sturdily built than the one that is installed now. Waiting for a dry weekend where I can install this along with a new 180 degree thermostat.

I haven't yet completed the repair to my car to see how well this works but it's a hose......not much more to say. It fit and is in new condition.

Great quality product. May have to trim the hose for the GM (3100 / 3.1L V6), (3400 3.4L V6) applications. It's a great buy for the price, they are becoming hard to find..

The hose needed to be trimmed to fit the jetta. Other than that, I can't complain.

Fit well to 2002 Sonata LX V6.Though not an easy stuff to do without a lifter. I suggest using, or at least prepare one ready, a worm gear hose clamp for the lower end instead of the genuine spring clamp as it's very difficult to move it in when you not have a lifter.

Good fit on my 1998 Suburban. I normally buy Gates or Goodyear hoses, but this one was quite a bit cheaper and the quality is on par with the others. It was exactly the same shape as the OEM hose and went on perfectly. As long as it holds up like the other makers, this is a great hose when you're working on a budget.

You will need the quick fit there's no way to possiable get oem hoses off the plastic ends the clamps they use for BMW are pressed on impossiable to re-use had to overnight the correct quick fit hose to put car back together if not for that they are as described

Perfect fit for my '01 Cherokee, but I had to use my old spring since this doesnt include one. Not sure how important it was, but im surprised it didn't come with the hose.

It was the right configuration, but I had to trip off both ends to make it fit exactly. Not a big problem.

Good quality and great fit for my 2006 Ford Explorer (V6 4.0L). Purchased when I replaced the radiator for my vehicle.

Not much to say, it's just a water hose. Simple to install and I've never bought one that didn't fit.I'll be upfront and say this, I have a bias towards DAYCO products. I prefer their water hoses and drive belts. I think they offer better material quality, fit and durability over the usual competition, e.g. "Gates" or "AutoZone Branded Products.Having worked at a popular Autoparts store and Speedshop for a number of years, it's just my opinion that DAYCO are the most reliable.

good hose. I paid 7$ and the next day it was $18. The upper hose was $4.00 and the next day its 15$. try and figure out this lottery!

Quality seems good, and fit well on 1992 Camry. I guess that I will know more after 100K miles and the radiator leaks or not.

It arrived in a timely manner and has been installed on my vehicle's new radiator. It seems to be quite good and I don't anticipate any problems.

I have had a lot of problems with poor quality replacement parts lately. This one did what it was supposed to and gave me no issues so I'm happy with what I got for the price here.

its rubber, it holds antifreeze, and doesnt leak, what more could you ask for? it does what its supposed to do.

Dayco quality hose was the correct fit for my 2007 Chrysler PT Cruiser quick delivery for this time of year .The thickness of the hose allowed me to reuse the spring hose clamps again .All is good

Didn't need to replace it, just bought to have on hand. Other day I hoses have been great and have never let me down.

I bought this with a replacement radiator AutoPartsWAY had put a plastic loop threw the hose. I imagine it makes it easier for storage, it doesn't leak because its close enough to the end but it just seems like a odd thing to put a hole threw a hose that's supposed to hold water

This hose was correctly shaped for its purpose, installed without incident, and has been doing the job for awhile now.

This hose worked great on our 1984 Toyota Celica GT fastback. Fit fine between the intake and the bypass line coming out of the water pump.

Great fit, no problem with this product and I recommend this products to anyone who need to replace heater hose.

This hose was a perfect fit for my 99 Jeep XJ. It seems sturdy enough and hasn't leaked or deformed or anything after a week of use so I'm happy so far. Two things to note about replacing the lower radiator hose with this product: One, it does not come with a new inner-spring and is soft enough when cold for me to easily collapse it with my fingers so you should definitely pull the spring from the old hose and put it in this one before you install it. Two, it doesn't come with clamps so you will have to reuse the ones that you already have (no surprise there). I recommend putting a screw-type hose clamp on the end where it attaches to the water pump, as there is little room which makes the factory spring clamps difficult.

Check your product factory item number online or call local auto parts as sometimes the wrong product is sent. These are new so they do the job. Grab new clamps as the old ones do wear out. Good luck.
