Broken top nipple on radiator
I guess that top nipple is easy to break. My mechanic called me to give me the bad news that I needed a new radiator because the top nipple broke when they were trying to replace the water pump. Koyorad $289.10 plus labor $241.90 plus coolant plus tax. Total $585. Arghhhh.
It caught me by surprise that this happened. I wasn't expecting it. I didn't research the part to be careful not to break the nipple on the radiator. Double arghhh.

FWIW, I replaced my rad with a unit on EBAY that had a lifetime warranty and only paid 75 bucks for it (free shipping too) and made in USA. Labour to replace it should only take an hour or less.

First of all, indeed the nipple becomes a small obstacle when replacing the pump. I cant tell you how many times I would have to alter my positioning in order not to damage/break the nipple. As many have said here in the forum, it is east to forget about, lean on/hit and break it.
Secondly, that's an awful high price for a radiator. If my memory serves correctly, Chris (Raodfrog) accidentally broke his rad nipple and had to replace his, but purchased his for between $50-80.
Lastly, make sure they are using Toyota coolant, as I've read and learned that OEM fluids with this vehicle are best whenever changing/flushing.

Thanks a lot for sharing, sounds very good..
wish you could produce a youtube video on this

I did this job back in September. It's simple:
1. After you get all the engine covers off and drain the coolant, you want to remove the coolant reservoir tank.
2. Remove the air inlets.
3. Remove the serpentine belt
4. Disconnect the dipstick tube. You aren't removing it, you're just moving it aside.
5. Remove the water pump pulley.....YOU DON'T NEED a special tool (SST), mine removed easily with just a socket and a pry bar or screwdriver to hold the pulley in place.
6. Remove the water pump. When you replace the pump, I would make sure you torque the bolts all in proper sequence. All the bolts have different torque specs. Lots of diagrams on google that will tell you the specs and sequence.
I also replaced all my hoses and all told, I think it took me about 2 hours (including refilling the coolant and purging the air), and cost me 75 dollars for the pump and hoses.
MAKE SURE YOU USE TOYOTA COOLANT. Or, you can also use Zerex Asian Formula coolant that you can find anywhere. But FWIW, Toyota coolant was only a dollar more per jug, so why bother?

Great Write up. Also identified leaking water pump during fuel pressure leak recall. They asked for $800. Replaced mine from above link on ebay for $37. Had some problem removing the thermostat housing. The refill tank had to be removed and when I removed the hose going to the radiator the molded appendage came off with the hose. Had to drill for a 1/8 NF27 brass pipe from Home Depot to screw into the radiator top with a brass nut for more surface area and JB Weld several coats to get a strong fillet for the connection. Needed a new hose clamp and was back in business.

Reviving an old thread here, but does anyone have the torque sequence? Searched Google and CL but I couldn't find it. Could have missed it....
I know the torque specs are ln this thread but not necessarily the sequence. Thanks in advance!

I PM'd you. Lexus doesn't have a sequence, just torque values. I would tighten the A bolts first, then B, then C.

Last night I ordered a new water pump, upper and lower rad hoses and belt. Now I'm thinking I should have ordered a new tensioner. Any thoughts on replacing the tensioner? Also, can you remove the lower coolant hose from the radiator from the top or do you have to remove the undercover shield and get to it from underneath the car? I'm getting old and hate crawling underneath the car - I did my 27th oil change on this car today and realized the mind is willing but the body not so much.
