DIY Gone wrong - Knock Sensor and Coolant Gasket Question - Need Help
Hi all
I am halfway through a starter DIY on my GS400. I've encountered two problems I am hoping you can help me with.
1) I've managed to break one of the two knock sensors (pics 1 and 2). I've broken the securing mechanism (locking clip) on the connector from the cabling to the ECU and I've also managed to break the plastic connector of the knock sensor itself (the bit that screws into the engine block).
So I have two problems on one sensor. For the connector on the cabling, what can I do? Can I use a glue to secure the sensor (high temp location)? What would you do?
For the knock sensor itself, I figure I have to buy the sensor itself. Can I buy at Toyota if Lexus gets greedy? Am I right? Also I really don't want to dig into the manifold again. Are knock sensors common failure items on the GS400? Would buying aftermarket (kragen) be a bad idea?
How do I get the sensor off (what size metric wrench do I need)?
2) I've managed to damage the gaskets on the coolant bridge that you remove to get to the starter (pic 3). Any idea what you call this part of the engine or do you have a part number?
Any help appreciated!

You can secure the connector with zip tie,but don't glue it. You can call Toyota for the knock sensor ,but I don't know the Tundra uses the same sensor or not. I don' know about aftermarket knock sensor, it's your money and your labor
