My Lexus GS300 overheated while my friend who
I let borrow my car for 3 months was driving it & needless to say my friend doesn't know much about vehicles. So it has an automatic shut off when it overheats so he let it cool off then added 1 gallon of water let it cool off completely the rest of the way. He didn't know that once you start the car that the valve opens and you have to add more water so without doing that he started driving down the road again made it about 2 miles and it overheated again and now wont crank. A friend of mine's uncle is a mechanic and checked it out for me free of charge before I had it towed into a mechanic shop and let know that yes it is a blown head gasket. I have also been told I'm probably better off just replacing the engine.

when the car starts it run perfect then just stalls out like I turned the key off? there are no codes being stored in the ecm!


Was advised that I need to replace the valve timing gear; it's leaking oil. How much should this cost? Thank you.

I could not see nothing on the dashboard. it would not show nothing at all no blinking signal no nothing!!! but it was still with power as i drove. and i tried to roll the window down and it would not roll down while the lights were out. after awhile pass the dashboard lights came back on again. this problem as happen twice today and once last week. Do you know what this could be? I took it to auto zone and they told me my battery, alternator, and starter was reading normal codes.

how should this be repaired?

everything in the car is okay. no check engine no oil light . there's no other light is on too.

back up light driver side is not working passanger side works fine I did checked everything else works it seems no power on driver side wire did changed the bulb still not what else could be did checked fuise box it looks all good and wires all connected, thanks for your help

My car just started jolting when I push down on the brake all the way. I took it to 2 different shops who told me it looks more like the ECU unit and not the transmission. Because this is a common occurrence these units are hard to find (because this is so common) so they advised me to take it to a Lexus dealer. I took it to a Lexus dealer and the service representative told me it was the transmission and quoted me very high prices. I said are you sure because both mechanic shops agreed what it was and told me it was NOT the transmission. Has anyone had this problem and knows what needs to be fixed?

I don't see any vibration engine runs smooth but when I put my foot on the break pedal it getting too loud and I did put new pcv walve still same what would be the problem thanks

Very low rpms and when I step the gas nothing happens, I have to restart and that usually fixes the problem

New heads as well, changed solenoid. now ECM problem we think. Any tricks to turning off check engine light.

I have had a new battery and cables ,and new alternator installed.. The dealer even made a new key. But every now and then ,you turn the key and nothing happens......Is there a neutral safety switch or something else that they are missing???

I have tried disconnecting the battery and checking the fuses under my driver's seat;I don't know where the fuse bow is under the hood though. I wouldn't even know which fuse to check.

The battery is fairly new so it cant be that. I seem to think something is on and draining the battery because when the car wont turn on, I jump it with cables and then it works. Does anyone have any ideas or suggestions?

very curious I've never owned this car before i recently bought the vehicle off a private seller so to day i went to work car started up fine for the past 8 days of purchase but i see the interior clock stays on and i have to manually turn off my radio whats going on

99 Lexus gs 300 has bad cat converter car has 240,000 mile on it the car still runs great ,what is the cheapest way to repare tihs I ve been adviced that I should take off the cat converter clean it with break cleaner and soak in the water with soap and put it back it should work fine,do I need new gasket or use the one already there ,thanks so much for help

The service shop I took my car to after it failed emissions due to some thing to do with the gas cap and the tank itself, says they need to drop the tank to get to the top where the parts are that need to be inspected. They say they have to drop the majority of the rear end to get the tank out. They $600 just to drop the tank. Is that accurate? The machine repair tech where I work says that is crazy, car manufacturers do not build cars with gas tanks that inaccessable since it is a system that needs repair often.

The main line fuse is located on the left side of the car, under the hood, and seems to be a part of a bar. What is this bar called and how do you replace this? My friend "Jerry rigged" it for now but I need to get it fixed as soon as possible. Will this be expensive to replace?

You know besides normal maintenance. I just bought car a few months ago. It has been well taken care of since new. Thanks! Oh yeah, the cruise control stopped working recently. I have not had it checked yet.

Guys Please help me. This thing embarrasses me all the time while I race with my friends. My car responds late to the gear. It doesn't change on gears on time. First I thought that it's a problem with the make but no I raced with a friend who has the same car and his car's is better responding. Please help :(
