I replaced mine with a Koyo radiator,the fit and all the bracket are exactly like the oem radiator.Perfect fit no problems,a really good made radiator.. :D

Here is your web site to check out how its looks ;) http://www.auto-couture.com/catalog/lexus/sc400/#

B) Check out page 14 or 15 and try resealing the headlight. Make sure the check valve is still there on your vent hose and that your sockets still have a good rubber seal. If your check valve is gone and you cant get any used one,then seal the vents.I resealed 3 units already and it gets easier everytime....Good luck.. :D

I think adding a small condenser fan would be the best idea.Trying and revert back to r12 would take buying a new accumulator and draining all the r12 oil and evacuating the system.If you dont do it correctly you'll eventually wipe the ac system out due to contamination.Getting more air flow on the condenser unit would be the best idea.... B) :D

:) Try and do the repair 1st before buying another h/l asm. It's not hard and buying another used unit does'nt guarantee its gonna be completely sealed. :) People think it's a hard job to take these units apart,but it's not that hard just follow instructions and take ur time. :D :D...Oh ya try and check ur vent tubes and sockets,that they are still sealing. You can still buy the sockets from the dealer cheap,but the vent tube you cant.The vent tubes are 1/4" ID and you can stuff the tubes with a sponge or honey comb type material.The sockets dielectric grease the rubber before twisting them back on. GOOOOOOood Luck :P B) .

Try the oven technique,baking the headlight after you remove the bulbs,vent tubes,rubber for the headlight bulb and the metal bracket on the end.Bake on a damp rag in a pan for 10min and split the unit from the bottom with a long handle gasket scraper its easier and faster than a butter knife,plus it will go deep into the adhesive sealer). Once you split the h/l unit ,remove 1 screw for the lens and take a part the h/l assm.Clean the reflector with a 3M glass cleaner(cause the others leave a residue)and clean the clear lens with meguiars plastic cleaner and polish.Reassemble and silicone channel of plastic housing with rtv clear silicone sealer.Press halfs together as tight as you can and bake in the oven for 5 more minutes,take out and press down on unit some more on a soft rug or carpet to seal h/l unit tighter together.Silicone around unit completely and put all the hardware back after its dries. :) :D Easy huh...after the 1st h/l it's super easy.
