#4481 of 4691 Re: Replace Sparkplugs V-6 Highlander [wtacoma] by electricdesign Jan 12, 2009 (7:18 am)
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.
#4482 of 4691 Re: Coolant leak in 2001 Highlander [electricdesign] by retropia Jan 15, 2009 (2:50 pm)
Replying to: electricdesign (Jan 12, 2009 7:08 am) Yes, I was able to fix it. Someone on another board posted detailed instructions on how to install the optional engine coolant heater on a Highlander Hybrid, and his photos helped me to figure out what to do.   As you suggested, I first drained coolant from a petcock located to the right of the oiil filter. I used an old section of garden hose to catch the excess coolant.   The hardest part is that the plate is located under the exhaust manifold and there isn't much space to maneuver, even with my skinny wrists. You have to work your arm in between the exhaust manifold and electric fan housing. It would have been better if I could have removed the manifold or fan housing, but I was concerned that I might mess it up putting it back together, so I just worked the best I could within the narrow space.   It was time to do an oil and filter change anyway, so I drained the oil and removed the oil filter, which did free up some space. (The coolant plate is located just to the left of the oil filter.)   Then I removed the two nuts and pried loose the metal coolant plate. It pried loose easily, because there wasn't much sealant there. It must have originally been overtightened and/or not enough sealant applied.   I cleaned the mounting surfaces with a scotch brite pad, then applied a fresh bead of Permatex high-temp silicone to the metal coolant plate, then tightened it according to instructions on the Permatex package.   So far, it is holding coolant fine and no more leaks.

Replying to: quattrohead (Jul 31, 2008 8:51 am) Totally forgot to update this, sorry !!! Turned out to be a broken ABS sensor ring on 1 of the rear axles. The Toyota tech could not/ did not guess which one it was so they replaced both, ouch. Anyway, all fixed and back to normal. Bit of a lemon for a Toyota, 2 problems in 70Km !!!!!!

#4484 of 4691 '05 Highlander: map light drained battery by sde Jan 18, 2009 (5:21 pm)
Oy. My wife left one of the two map lights on in our '05 Highlander Limited, and the battery drained. It jump-started successfully.   Is there no automatic protection for this? Don't the lights go off automatically after some period of time if the engine is off?   We also have an '05 Corolla; I have the same question regarding that car and its map light (in case anyone in this forum knows).   Thanks,   SDE
#4485 of 4691 Serpentine Belt by byumgr Jan 20, 2009 (6:48 am)
I have a 2005 Highlander Limited 6cyl. with 59,200 miles. I was told that the serpentine drive belt should be replaced. My question is, has anyone had theirs replaced this soon and if so, what was the total cost including labor. Replies to this message: mikefm58 (Jan 20, 2009 3:35 pm)

Replying to: byumgr (Jan 20, 2009 6:48 am) I've got an 04 HL 4 cyl with 44K miles, no problems so far. Sounds like your service advisor has a boat payment due.
#4487 of 4691 Whistle noise from front heater by krb1 Jan 22, 2009 (4:50 am)
I have purchased a certified 2008 HL 3 months ago with 25,000 miles on it. Since I started using the front heater, a high pitch whistle like sound comes on and lasts anywhere from 30 to 60 seconds. I don't turn the heater on till the engine is warm, but it does not make difference. I even tried to drive with the heater on and then turned off. About ten minutes later I turned it back on and the noise started all over again. I just took the car for 30,000 mile service and asked them to fix the problem. They told me that they changed the air filter which had some debris in it. However, yesterday I tried again and the noise is still there lasting even longer and sounding even louder. Did anybody experience similar issue? What could be the problem? I am going to call the service this morning again. Thanks in advance. Karolina Replies to this message: tsotsi (Jan 23, 2009 7:38 am)

Replying to: krb1 (Jan 22, 2009 4:50 am) Just a wild guess. Could it be a fan bearing?
#4489 of 4691 One more question - noise heard while in reverse by krb1 Jan 23, 2009 (4:46 pm)
I have posted message #4487 and just wanted to add that I have one more issue. Only when in reverse and only sometimes I hear noise from underneath like something is loose, esp. when I break to slow down. I asked the dealership to check it out along with the heater noise. They checked and said that everything is O.K. and nothing is loose, yet the noise is still there. Perhaps it's time to change the dealership/service. I am starting to wonder if they know what they are doing. The only reason I would hate to do that is services included with the purchase (free oil change, batteries, and tires as long as I own the vehicle). Also, free 30,000 - 60,000 - and 70,000 mile service. Replies to this message: bluenose2 (Mar 02, 2009 1:49 pm)
