Okay... So i'm driving back home from school today and my CEL turns on. 10 more miles to go. Hit up friend to borrow code reader. That's an extra 10 miles.

I get a few miles past my house to head to his and I start seeing the temp gauge fluctuate pretty bad. I pull over and pop the hood, very little coolant left. Time to head back home and pick up mom's RX450h to pick up the code reader. I'm guessing the coolant bypass pipe gaskets are shot. Didn't replace them when I did my starter a couple weeks ago.

Grab mom's keys, check under car, coolant pouring and no more coolant left in the expansion tank.

I get back home and plug in the code reader. P0325 Knock Circuit malfunction...

When I was doing my starter, the knock sensor plastic snapped off so I just epoxied the plastic back on.... Worked fine for a couple weeks. This sucks. I do not want to order a new knock sensor since they cost $140. Sewell Lexus shows 2 part numbers for the knock sensors, both 8961550010 and 8961512040 for the 1997... Which one is it? Going to just get one of these off Amazon instead.




Looks like i'm going to have to rip the whole top of the engine back apart, drop the trans and exhaust to get to the damn coolant bypass pipe gaskets (1634150010) and replace the knock sensor. Damnit.

What exactly do you want pics of? I just don't get how they're tied unless the coolant filled into the area between the banks and flooded to the wiring of the knock sensors.... I'm going to just order 2 knock sensors and replace both of them while i'm in there. Might as well....

Replaced gaskets, started car up and it immediately started leaking again. No idea what is causing it.
