  • Original Equipment Manufacturer (OEM) fit at affordable price
This replacement radiator fit like the original, was very easy to install. I think the people that complained about it not fitting had a car with a warped frame, every connector and screw hole aligned perfectly with the frame, hoses and fan assembly. It was actually easier to install then to remove the original part, I am original owner so I know it never had frontal damage that may cause radiator install issues. My only gripe is that the box it came in was open, with radiator exposed. After inspecting it, it looked damaged free thanks to UPS handling it with some care. My Denso part was made in Taiwan, just for your reference. ... show more

  • direct fit for 2000 lexus gs400
I knew that the oem radiators are prone to brittle plastic and subject to fail so when i saw the price of a denso direct replacement for $65, it was an easy decision. i was slightly worried since some reviews mentioned they needed to adjust some of the holes. for my application 2000 lexus gs400, it really was pretty good fit. i did take out the airbox and replace all the hoses at the same time. hardest part is trying to get all the electrical connectors to disconnect. all the screws for fan fit in the same spot. the temp sensor screwed in and didn't leak. The only slight adjustment was for the air box/air intake. in the original application, there is what can be described as foam weatherstripping between the radiator and frame of the front of the car. the old foam was not reusable. I assume it is to force more air from the front of the car and through the a/c condensor/radiator. i likely will try to find similar weather stripping to install at a later point but i don't think it's critical. so far so good. temp only goes slightly over the half way mark on my car. ... show more

  • Did not Fit
This was used for a 1998 Lexus GS400, which the Amazon Parts finder said would fit. The problem is once placed in the supports on the bottom with the correct grommets, the support clamps did not line up at all with the screws on on the top radiator support. The fan shroud also only fit 4 out of the 6 screw holes on the radiator, and had to be modified so that it would fit The grommets also had to be cut and modified so that the radiator could actually fit with the car. This is an incorrect fitment situation despite attestations that it would fit from Amazon. ... show more

  • Fits GS400
I bought this as a replacement for GS400. It fit the car just fine. I'm not sure if it's because of the age of my fan shroud or the tolerance of the fastener locations for the shroud on this radiator, but couple of holes didn't line up perfectly. But I was able to line everything up eventually with fasteners. This unit came with radiator cap. You would have to transfer your current sensor to this new unit. The swap is very self explanatory. Unplug upper and lower radiator hoses, inlet and return for transmission fluid line, un-clip all electrical to fan shroud/radiator. Slide radiator out with fan shroud still attached. Transfer everything over to new radiator, plug all unplugged of electrical and hoses. Refill coolant and transmission to proper level. Check for leak as car builds temperature. ... show more

  • Cap is a different size from OEM 2000 GS300
Functionally it's fine. I am not thrilled with the fact that all the fan shroud bolts didn't line up and the stock GS300 radiator cap does not fit. I have no idea what cap I will need to use if I need to change it in the future. For those two reasons I'd buy a different unit. Update; Supplied cap was bad. I can't recommend purchasing this unit.

  • OEM Quality Perfect fit
I Purchased this for a 2003 GS300 and it fit perfectly. Loosely insert all the screws before you tighten them down and it should fit snug like it should. This radiator is for a car that either is or will be 20yrs old so what exactly are you expecting? It to fit like the car was just built yesterday? Be serious with your expectations of things when you buy them before you write a bad review. ... show more
