04 RX 330 Coolant Leak-Engine Block Heater Cover Plate
I've seen posts on this in the past but I decided to put this up again just in case someone else was having a similar coolant leak. On my 04 RX 330 (105,000 miles) I had been noticing that there were occasionally very small puddles of red coolant on my garage floor, on what seemed to be random mornings? When no coolant residue could be seen at the hose connections from the top of the engine, I looked at the bottom and that is when I noticed the dried coolant residue on the bottom of the engine oil pan. Following that up you could clearly see that the coolant had come from the "Engine Block Heater Cover Plate" that is right beside the oil filter on the front side of the engine block. I figured I would include pictures to help others spot this issue, if they ever come across this problem?
Thanks

Had it in the Lexus service department today for the Brake - Master Cylinder repair recall. I mentioned the leak along with a picture of the defective seal on Engine Block Heater Cover to my service advisor. He said it wasn't a big deal and he took care of it as a "courtesy repair". There is no gasket there, just sealant and the plate, the biggest cost would have been the gallon of coolant it would have taken to refill and the technician's hourly rate of course.
I pays to have a good working relationship with your service advisor!
Have a great Holiday!!

Nothing beats spending some $$ with the dealer. It can give you a good return on investment.

Hello, does anyone know if the Engine Block Heater Cover Plate is also on a 2001 RX 300? Also is it hard to get to? What sealant is recommended? I have noticed a steady drip of coolant once system warms up and builds pressure. Thanks for any replies.

Had my '04 in last week for the pully recall and the ecm reflash tsb. Dealer called and said there was a leak next to the oil filter. This is a repair I would have gladly done myself, but my wife and I were having a long overdue day alone to do whatever she wanted to do. Told dealer to go ahead with repair. I figured that a happy wife was more important than $ saved. They put in a new plate and o-ring and changed the coolant. The bill was $280. I don't like to spend a days pay for an hour and a half of labor but that was my choice. $146/hr labor is high in my book. I've always done my own service and repairs so I may be naive about the current labor rates. Anyway, I took the car in with the reserve fuel light on and dirty, and got a full tank of gas and a complete inside and out wash job, so that was worth about $80. That softened the blow a little. The dealer was very courteous and followed up by phone the next day or so to make sure that we were happy.
