2004 LC w/288,000 miles. My original radiator recently went out and I replaced it with a Mishimoto. I also replaced both radiator hoses, clamps, thermostat all OEM including a complete flush with Toyota pink antifreeze. After driving for about 10 miles steam started coming out of the engine hood and when I pulled over I found that the drivers side radiator hose had blown off of the radiator and the other end of the hose was starting to come off of the inlet.
I called Mishimoto and the tech suggested that I go to the screw type hose clamp upon my prompting him. He didn’t think it was a faulty new radiator cap because he said he’s only seen that happen 2 times in 20 years. I did put a dab of dielectric on the hoses before installing them but it was a very small amount and the Mishimoto tech didn’t think that was a contributing factor.
I just finished taking everything back apart, cleaning the new hoses with dish soap and hot water, wiping the inside of the hoses with acetone to remove and trace of the dielectric, re-installing the hoses with stainless steel screw type hose clamps from NAPA (torqued to 4.5 Nm) and replacing the 3 gallons of lost Toyota pink fluid at $25 a gallon.
The Mishimoto radiator cap has a 19# rating. Anyone know what the Toyota OEM cap is rated at? Any ideas? Thanks
