#4451 of 4694 Flushing engines and gearboxes by tsotsi Dec 05, 2008 (5:12 pm)
It's too bad there is not more research on helping high-mileage cars reach even higher mileages. One school of thought about flushing is that after many years and miles there is a lot of crud built up on internal parts, in places where there isn't any kind of natural cleaning action. The result is that if you flush an engine or gearbox you had better flush it really well because the first result of a violent flush is that some of that crud will be washed into suspension where it will do real damage. So, if you are going to flush, make sure you keep flushing until all the crud you have knocked into suspension is truly gone from the inside. Anybody who has worked on old cars knows that even with flushing, a lot of nasty stuff will still be stuck inside the engine and transmission until they are taken apart and really cleaned.   My own idea -- not proven by any actual research (so take it with a grain of salt) -- is that it is better to just change the oil and let the crud rest in peace . . . where it isn't doing any damage. The only exceptions may be engines that are prone to sludge build-up.

#4453 of 4694 Ooops - gas cap off during car wash! by budh Dec 09, 2008 (11:14 pm)
I filled my tank yesterday evening in my 153,000 mile 2002 Highlander Limited AWD V6. Then went through an automatic car wash before driving five miles home. When I got out of the Highlander I saw the gas cap was off and was off during the car wash!   No issue with my five mile drive home.   What would you do to make sure it keeps running right after this error?   And now that I have reinstalled the gas cap properly, can I prevent the check engine light from coming on?   (I live in a fairly cold climate near the Indiana/Michigan state line.)   Bud H Replies to this message: electricdesign (Dec 10, 2008 7:28 am) herzogtum71 (Dec 10, 2008 4:43 pm)

Replying to: budh (Dec 09, 2008 11:14 pm) It depends on how much water got into the gas tank. You can add some gas tank additives that claim to dry the moisture out of the gas, but they only work for very small amounts of water, like condensation. You did not notice any problen yet because the gas floats on top of the water, the water rolls around on the bottom of the tank, it moves due to the motion of the car, until it happens to get sucked up by the pickup tube. You don't know how much is in there, but it is best to get it out, the most sure way is to have the gas tank removed and drained.
#4455 of 4694 Changing anti-freeze by mikefm58 Dec 10, 2008 (7:28 am)
I've got an 04 Highalnder with 41K miles, not much in the owners manual on when it's recommended to change the anti-freeze. What are the opinions here on when it should be changed? Also, is it as easy as simply draining what's in the radiator by loosening the drain plug? My old Honda CRV also had a large bolt on the engine block to remove that would drain whatever was still in the engine block. Are Toyotas like that as well?

Replying to: budh (Dec 09, 2008 11:14 pm) On my '04 there is a little spring-release flap underneath the gas cap that is always closed unless it is depressed by the nozzle at the gas station. I suspect your '02 is the same. If so, there is little chance that enough water got into the tank to do damage.

Replying to: mikefm58 (Dec 10, 2008 7:28 am) Here's what the manual says for a 2004 Highlander coolant:   Initial replacement at 100,000 miles/120 months. Replace every 50,000 miles/60 months thereafter. Refer to "Engine Coolant" in the "Explanation of Maintenance Items" section in the back of this guide for more information.   Pretty amazing if you remember the "good old days" when you changed coolant every couple of years.

Replying to: lmacmil (Dec 14, 2008 9:31 am) Yeah I did eventually find that after going through the maint. and owner's manuals better. I changed the anti-freeze anyway, but never did find the bolt on the engine block so I didn't get all of the old stuff drained, but pretty close as the specs say a little over 7 quart capacity and I ended up using 5 quarts.

#4460 of 4694 '05 Highlander w/ low coolant level - possible coolant leak? by 05highlander05 Dec 24, 2008 (8:19 pm)
2005 Highlander 43,000 miles   I opened my hood today to add some windshield washer fluid and I noticed that my coolant level was exactly on the "L" level. I also noticed some dried up coolant at the end of the hose that goes towards the radiator. The coolant level seems to stay the same when I checked it this morning and when I checked it when I came home. When I look in the coolant reservoir it is yellow on the top. Other than filling up the reservoir a bit does anyone have any other suggestions, should I be worried?   Here is a link to the pics: http://picasaweb.google.com/lh/sredir?uname=draganplavsic&target=ALBUM&id=528357- 4488921410145&authkey=S2JOcBVaJx0&feat=email
