Replying to: steve_ (Jan 08, 2009 6:09 pm) I don't guess they make too many pink Highlanders.   Not unless Mary Kay used Highlanders for the tax write off.   tidester, host SUVs and Smart Shopper

#4474 of 4692 Coolant leak in 2001 Highlander by retropia Jan 09, 2009 (8:21 am)
In my 01 Highlander V6 AWD, I believe I've traced a coolant leak to the "front" of the engine. There is a round plastic or rubber seal, maybe two inches in diameter, held in place with two nuts attached to studs coming through the edges of the seal, from inside the engine. This is located to the left of the oil filter, just slightly higher than the oil filter. I don't know the purpose of this rubber seal nor what is behind it.   There is a slow and occasional but regular drip of coolant that appears on the floor of the garage.   Has anyone else ever encountered this, and/or does anyone know what this rubber seal is for? It's not particularly easy to get to as it is behind the exhaust manifold, and I'm thinking I'd rather take it to the dealer than attempt to fix it myself.   Thanks!

Replying to: retropia (Jan 09, 2009 8:21 am) Thanks, I think I've determined from researching at another forum that the seal in question is called an "engine block coolant passage plate" which is used as a mounting location for an optional engine block heater (not certain about that last part) and that leaks here are not uncommon.   It sounds like it might even be something I can fix myself.

Replying to: retropia (Jan 09, 2009 9:11 am) Interesting - my last few cars have all had block heaters but they were installed where the freeze plugs are. A plate would make it easier to install one of those gizmos.
#4479 of 4692 Replace Sparkplugs V-6 Highlander by wtacoma Jan 09, 2009 (9:31 am)
It's time to replace the plugs in our 04' Highlander. Has anyone done this? I'd like to know how involved it is. Does the intake manifold need to be removed to get at the rear bank of plugs? They look difficult to get at. Replies to this message: electricdesign (Jan 12, 2009 7:18 am)

Replying to: retropia (Jan 09, 2009 8:21 am) I found the exact same seal with a metal plate over it held by two studs and nuts, that you described, on the engine of my 04 V6 Highlander. Mine is not leaking yet, but it is good to know about it, so I can keep an eye on it. It looks like it would not be difficult to replace, it would require draining the coolant from the engine, removing the seal, installing a new seal, and refill the engine with coolant.

Replying to: wtacoma (Jan 09, 2009 9:31 am) I am also faced with the spark plug changing job in another 7,000 miles, my 04 V6 Highlander should reach 120,000 miles this summer, which is when they are scheduled to be changed. I took a good look at it this weekend, and it appears to me that the only way to have enough room to remove and change the spark plugs is to remove the upper intake manifold. The engine is running so perfectly smooth now, that you can't even tell that the engine is running while idling at a traffic light. Being that is is so much work to change the spark plugs, I'm thinking that I won't change the spark plugs until they actually need changing.
