Someone posted another thread about their mshimoto blowing off hoses- due in part to higher pressure system and in part to lubing the inlet/outlet with dielectric ( not good) - the Mishimoto cap was a 19psi cap. I noticed that the CSF aluminum posted above is a 20psi cap. OEM is a 16psi cap. Not sure how the increased system pressure may affect anything but it if the system was designed for 16psi- does 19 or 20psi impact gaskets, fittings, other smaller hoses through the throttle body-head gaskets ? Higher PSI cap will increase boiling point of a closed system, but is it worth it? Does it matter if the CSF need runs a 20psi or 16psi cap? I would run the OEM cap on the CSF and measure running temps against OEM radiator.
@abuck99 That's a nice observation. I wonder what CSF or Toyota would say about the additional stress on the other components in the cooling system in reference to the 100 series?
I was also interested in how much that actually effects boiling temps.

@Buddysuede I read somewhere that for every psi increase at the cap you add 3 degrees Fahrenheit to the boiling point- so Factory is 16psi, Mshimoto 19psi cap = +9degreesF to boiling point and a 18% increase in tank pressure, CSF 20psi cap = +12degF to boiling point and a 25% increase in tank pressure. Pretty close to your chart for 50/50 premix.

I have no idea how or if coolant system pressure at (for example) head cooling passages, or water pump or the small coolant lines like oil cooler or throttle body is impacted by increased radiator tank pressure-
 
@abuck99 is the system immediately under pressure, or does it climb relative to temp? I’m curious, and trying to study up on this aluminum option as I’m considering it when I do the first timing belt change on my truck and all the associated things that need to be replaced.

Perhaps the AL can handle slightly more pressure at high temps thus the 20 psi cap? I don’t know but I would be curious to see how it would perform with an OEM cap … I am on the fence and would like to learn more about the longevity of AL radiators over OEM if they are built well. CSF is big in the Porsche world (where OEM radiators are already aluminum) but didn’t know they did anything for cruisers.
 
@abuck99 So after your astute radiator cap psi observation on the CSF I started to pay more attention to the system and sure enough saw this. After running the engine around town temp was at 190.4. I didn't see it ever go any higher than that during the trip but I did see a rather large bulge in upper radiator hose while under pressure. I did not replace the upper radiator hose when I replaced the radiator. Luckily, I replaced every other one but that one, so the rest look good. So perhaps it's old and tired or perhaps the 20psi of that system is exposing weaknesses in the cooling system and you are correct. Thanks for the observation, was most likely headed for a busted hose down the road somewhere.

Either way, I'm replacing that hose and switching the radiator cap to OEM.

That hose is no bueno
 
I'll replace the clamp as well - not sure when that got put on there.

Is the blue painted pulley a certain brand? I noticed that on mine and figured it was a cheap aftermarket part.
 
@plainjanefjc The blue part is the fan clutch base. I just replaced this with this radiator. Fan clutch is 100% OEM Toyota Part 1621050051.

Bump on this existing thread, I have a 2006 LX on 33s , I am leaning towards Denso Radiator part number 221-3152. I called my local Las Vegas Toyota dealer this morning and guy quoted me $950+ OTD which I find way overpriced, or is that the going rate these days for an OEM radiator?
So looked for a better alternative and used the part numbers you all shared here, I came across this: Denso Products 221-3152 Denso Radiators | Summit Racing - https://www.summitracing.com/parts/dnp-221-3152. First time to order online from Summit, any good/not so good experience from them? Thanks
 
Bell Lexus or Marietta Toyota will have a better price shipped to you. Marietta shipped mine and it arrived flawless.

You are spot on Bell Lexus in AZ. Thanks for the recommendation.
 
@OEMGUY0720 The link you shared from Summit has it at $250...heck, even Amazon has it for 160. Why would you pay $531 for it?

I want to avoid doing the swap again after 2-3 years because of a failed radiator not to mention the potential damage in the event it fails (atf mixing with coolant, overheat and warped head, etc) so I am weighing in options. Of course OEM is the best in terms of longevity and reliability. All of us are trying to save a buck, and a $531 price for an OEM radiator is definitely better than my local dealership price of $950+.

My local dealership prices arent quite as bad as yours but they are up there! I priced one 80 miles away and it was in the 550 range before tax. But didn’t feel like spending half a day driving.
 
Hello

New guy here. Will the LC OEM radiator fit the LX? I recently acquired a clean '00 LX from AZ but don't know the maintenance history and would like to get all the major maintenance done before winter. I know both vehicles are essentially the same but with the slightly different front end is the LC and LX radiator interchangeable?

Thanks
