Python- SW- thanks!

Should I use synthetic in my '92??....I was told not the older engines??

There are people that think using aftermarket hood struts will cause the world to end too.

I do think that the people on this forum are only concerned with getting the best performance possible from these fabulous cars....and again thanks for all the great info, and discussion, everyone. :D

Can you point us to something that says the green coolant won't gum up radiators when changed at the factory reccomended interval?

Certainly, the factory repair manual for my former '95 says that the coolant only needs to be ethylene glycol type; never do they make any reference to a specific brand or color coolant. I'm sure if the engineers thought the green coolant was going to harm the engine/radiator/etc., they'd say to use only the red Toyota coolant. The doom and gloom stories about what might happen if you don't use the Toyota coolant are somewhat comical to me since I've had green coolant in my past '95 for over 150k miles with no cooling issues at all--it'll idle all day long in 105* with the ac going without over heating. Around here, green coolant is less than half the price of Toyota coolant even if you buy it at the Toyota dealer.

yes, I also just looked at my auto service manual, and it said that the coolant should be 'ethylene glycol type' only. However, with the power steering fluid and trans fluid, they recommend Dex 2 only. I still think the toyota coolant will be better for the car in the long run, and will switch, but apparently the green type is OK.

My $.02 worth. I had taken my RX300 to Lexus to be serviced (60K miles) and they included - they said - change of radiator fluid. Well, now at 68K miles, I notice the fluid looks 'greenish-grey' and only comes to 'minimum' at the overfill tank when hot. A Lexus 'diagnostic specialist' sees it, suggests a little more fluid, comments that it was 'green' fluid that was in the radiator - not the Toyota long life (red). He kindly offers to fill up the water overfill tank a little, adds Toyota red fluid, tells me when I ask him if it is a problem mixing them "Not at all, but you may not like the resulting colour". I asked whether one or the other was best, and the reply was "Not". So, I would not worry about the colour of your radiator fluids. Enjoy life and your car.

interesting!!......i have green fluid in my toyota truck, and i used to always have green in my 95 camry....they both ran fantastic!...I still think i will switch in the Lexus, however....I like to baby this one.

HE IS A GREAT MECHANIC---THE CAR RUNS GREAT...AND I REALLY AM NOT GOING TO CONFRONT HIM WITH IT.

I'LL JUST TAKE IT SOMEWHERE AND HAVE IT FLUSHED AND NEW COOLANT PUT IN.

IF HE ASKS ME LATER, I WILL TELL HIM. HE USES THE COMPUTER FOR ALL HIS RESEARCH, SO I DON'T KNOW HOW THIS HAPPENED. O WELL.

thank you---thank you!!!!!

I am not going to take any chances with this car- it runs perfect...gets great gas mileage, and i have alot of time and $$ into it...I will get it flushed ASAP>

Thanks everyone- I really appreciate all the great info you have all taken the time to help me with!!

:D THANKS

thanks everyone!

I usually use Mopar red, is that a good one?

From what everyone has suggested, I assume it should be flushed and changed, but no great hurry.

Where do I find Nulon Red Long Life..? Any Auto Store?

How do I tell if the radiator is aluminum?...I think it is the origional..

I JUST HAD MY RADIATOR FLUSHED AND MY TRUSTED MECHANIC WHO HAS NEVER DONE ME WRONG PUT GREEN COOLANT IN MY LS!!

I TOLD HIM THAT IT NEEDS THE RED STUFF, BUT HE SAID IT DIDN'T MATTER.....!!

WILL THIS HURT MY ENGINE?? SHOULD I CHANGE IT ASAP, OR CAN I CHANGE IT NEXT FLUSH?

water pump?

thanks ED...your car looks like mine.

jc- thanks- NGK I have heard they are very good...hope I can find some.

are the LS 400 known to have electrical problems?

gonna install new sparkies.....what are the best?

Going to make a DIY?????????????????? :D :D :D

hardly no...just like to watch. B)

:D Jolly good. new2mud. much thanks.

is there any way to unplug a heater core, other than taking apart the engine?

I am hardly impressed with the pioneer system in my car....blaupunkt was the best car system I have ever had..pioneer is rather medicore.

A mechanic once told me, always keep your tank above 1/4 full...in the winter keep it full, and you should not have any problems with your cats.

I swear mine gets 30MPG- but I might be miscalculating...I really don't put any more gas in than I did my Solara, a few years ago, and it was 4cyl.

But ahhhhhh the luxury...

some one told me they had used Lucas products, and thought they were great..any opinions?

After driving an LS, nothing else compares...

I have never seen a problem caused by applying too much pressure to the cooling system other than blowing out the radiator or pump which would only happen if they were worn anyway.

thanks kennyr-

could a blown pump affect the engine performance?....if this were the case? Would the car stop altogether if the pump was blown out?..Would it even start?

thanks.

It sounds to me like an issue that the type of car is irrelevant.

The mechanic has no idea what the problem is? What kind of symptoms is she having?

yes, I agreed, the type of vehicle is irrelevant.

I was just wondering if anyone else had had a similiar experience: in my many years of owning cars, I have never heard of anything like this.

thanks

Yes, we are wondering if too much pressure was applied during a coolant system pressure check.

The car was running at full capacity, engine was great, but she thought the water pump might be leaking, so mechanic did a pressure test and the water pump seemed OK, but now the engine seems to be sluggish, and the vents are blowing out dust and dirt...wondering if something was blown out..regarding the engine or something..of course the mechanic is not admitting to anything...and will not tell her the amt of pressure applied.

thanks

Why did she think the pump might be leaking? Was the coolant down? Did she see a puddle or traces under the hood? Was the car running high temps? And when you say "her mechanic" do you mean this is someone who has been regularly servicing her car? Is he an independant or with a dealer? If he can't diagnose the problem or even offer an opinion, I would tell him you're going to have another shop look at it. I hope you have an itemized bill for his services.

Yes, there was coolant dripping from the pump area, not very much , but enough to be somewhat concerned, so she took the car to a mechanic that someone had recommended, an independent guy, and just wanted him to do a simple pressure test, and she thinks he overdid it and blew something in her engine, because she is now having very sluggish engine performance, whereas it was very normal before.

So _Question _for anyone who whould like to respond:

Is it possible to blow up something or damage an engine part --rings, cylinders, gaskets, if enough pressure is applied....I am not saying this is what happened, but am holding it open as a possibility, only. How strong are these pressure testers? I can't believe any certified mechanic could make such a terrible mistake, if indeed this is what really happened.
