    I've come across multiple radiator threads in my search to find out "what radiator fits best/easiest" and have seen multiple part numbers and manufacturers listed.

    The job looks stupid simple, so I don't need help with replacing it.

    I'd like to know what replacement is a direct fit for a 2001 V6 Automatic (Prerunner).

    I've read about mounting holes not lining up and such and would prefer something that fits without any customization. Post your brand/part number radiator you went with and how much you spent! Would like to order one today so I can tackle it on my days off.

    Second, what coolant are you running? I run Summit Non-Glycol in one Corvette and Red Line Supercool coolant in my other Corvette.

    The Toyota parts department across the street hasn't called me back yet; left a voicemail.

    The parts manager there recommended awhile back that I go through their website; it gives people a discount vs buying in person since there is no actual 'person' taking the order online and it doesn't affect their sales/numbers.

    PS I'm a finance director at an automotive group across the street from Toyota. So yeah I'd like to go OEM, but the website shows 2 versions for an automatic Prerunner, and says neither of them are available to order.

    I think DENSO outsources a lot of parts now to China unfortunately, if AISIN made one its more likely Japanese(maybe)

    Oem is Harrison. So a GM radiator. I'd avoid OEM at all costs. They tend to have a tendency to leak or crack at the aluminum/plastic weld.

    I'd go Denso. I recommend Toyota Pink premixed, but I'm sure any coolant is fine as long as the different types aren't mixed.

    Update; replaced my radiator, drained and filled my transmission fluid, and replaced my radiator cap.

    It's been awhile since I've had a vehicle with a fan clutch so I have to ask this -

    After I installed the new radiator, and proceeded to top off my radiator with Toyota premixed coolant, I reached the point where there was a bit of fluid left in the funnel. I squeezed the upper radiator hose to remove some air and topped off again. Turned on the truck and I swear, it was on for over 40 minutes before I think the thermostat opened up. Though, I don't think it opened up because the fluid level never changed as I waited to top off the radiator some more.

    It's pretty hot and sunny today so I expected this to be a 15 min process.

    About 45 minutes with the vehicle on, I think the thermostat opened up because the lower radiator hose was finally getting a tad warm. I'm not sure if it was the engine bay though that warmed up the hose or if coolant actually flowed through it because the coolant level never changed.

    The temperature gauge stayed at just a hair less than halfway the entire time, and the fan was spinning the entire time. Thought the fan only spun when it got warm enough for the clutch to "harden" and spin?

    Oh and here's why I replaced the radiator -

    The vehicle has never overheated, but I noticed that there was "dried coolant" on the radiator shroud. After inspection, I found this crack in the plastic tank. Again, the vehicle has never overheated even though it's really warm where I live, and I just replaced it as cheap insurance.

    Oh and when you swap your radiator out, you don't have to take apart your shroud -

    I just did this the other day and I had the same issue. I had the funnel about half full and started squeezing the hoses until no more bubbles came out. Then I cranked the truck, flipped my scanguage around so I could see the water temps, and watched for bubbles. They started coming, once the slowed down I started squeezing the hoses again and more came out. Once I got up to temp (185), I squeezed some more and got the last bit out ( I hope). I've since driven it a few miles and it ran about 10 degrees cooler than it did before (changed the thermostat and put jiggle valve at 6).

    Hmm, that's the thing though, I never got any air bubbles coming out and never had to refill at all for the entire 45 minutes that the truck was left on.

    I only had to refill when I squeezed the upper radiator hose a few times and that was when the truck was off.

    I drove it around for half an hour and the temperature is just slightly less than I'm used to seeing it.

    Did you drain the fluid out of the engine? There should be some still left behind the thermostat, no?
