20 Most Recent 1986 Toyota MR2 - Page 4 Questions & Answers

If the valves are bad so are the piston rings

Have you checked the under-hood fuses?

Hi,
I just was reading this and had a few thoughts for you:

1. Is it possible the thermostat is installed backwards? That's an easy fix.
2. Is the radiator fan working?
3. If the pumping action from the water pump seems normal yet the engine still wants to heat up, it's possible that the radiator is clogged-up.
4. Worst case... If with the radiator cap off, the coolant literally blows out of the opening... and the engine has really heated up recently... you may have a blown head gasket. If you suspect this, have the oil drained for inspection of coolant in the oil and don't run the engine anymore. A major fix would be required.

Hope some of this helps you. Good luck!

Hello, and welcome to FixYa. Please allow me to assist you.

The MR2 auto transaxles are very reliable units. Just change the ATF with the correct fluid every 30,000 miles. If it has high mileage, 90 + K miles, and is a dirty colour, I'd recommend a transmission flush. This will remove all of the dirty fluid from the system.

The MR2 non-turbo was a fun car, and had very few comon failures.

Try to stay away from the turbo cars, the turbos are know to fail, and the parts and labour to replace the turbo is very expensive.

The MR2s are rather quirky when it comes to servicing the cooling system, you have to bleed the air out. The necessary procedure is in the owner's manual, or online.

Other than those items, the MR2 is a very decent and reliable car. A little noisy, with the engine right behind you, but, that is part of the fun.

Thanks for choosing FixYa for assistance.

Best bet is the gasket. After removing the head have it serviced professionally, replace thermostat and water pump and timing belt while in there

I have a 1985 mr2. First off how many miles are on the vehicle. Have you checked the coolant level? Has any service been done recently? You may want to try flushing the whole coolant system and replacing the coolant. It is very easy to get air bubbles in the system which can overheat it. Also are your fans working properly in the front? Once I have more information I can assist you further.
Thank you,
Lee

You can find all the paint codes at this link, good luck!

Every clutch has a "throw-out bearing", and the proper term is Release bearing.

You should purchase a good quality complete clutch kit, and make sure that the clutch kit also comes with the pilot bearing as well. Be sure that they re-machine your flywheel to restore proper clutch operation.

Here is a link for you check out for yourself, and you can see that the release bearing and pilot bearing are both included in these clutch kits. You should then be able to purchase a new clutch kit from your local parts store.

look for a better one,
mr2 are very high dollar to fix

You would need electrical know how to use the fuse block to get power. Otherwise get power directly from the battery but go through an inline fuse about 20 amps. The fuse needs to be at the battery that way if there is a short power stops before you start a fire!

try taking off the air cleaners air duct that goes to the engine, with the throttle open spary some carburator cleaner into the intake. Spaying for about 10 secs. should be enough. then start it up. if it runs you know you don't have any fuel going to the engine and a fuel pump would be a very possible cause, other causes for no fuel would be a fuse, a relay, or a computer related problem. Good Luck

This is complicated. You might need to drive to the garage.

If you want a detailed diagram you might need to come on to premium payment mode.

Cheers.

Behind the key tumbler there is an electrical part of the ignition switch.You will have to dismantle the plastic covers around the steering column to gain access to ignition switch.let me know if this helps

This sound like a more common issue than we in the mr2 community would like to see. The cars are old and the ground wires tend to wear out. But normally the gas pedal cable becomes the place were it grounds out and start a fire. get a cheap ground wire kit for the engine compartment as well as put a few on the battery. Also check existing ground wires. Hope this helps!

A transmission solenoid is an electro-hydraulic valve that controls fluid flow into and throughout an automatic transmission. Solenoids can be normally open or normally closed. They operate via a voltage or current supplied via the transmission computer or controller. Transmission solenoids are usually installed in a transmission valve body, Transmission Control Unit, or transmission control module.

The rapid clicking sound is the starter solenoid. What it's telling you is, the battery voltage is still too low. Either you have a poor connection with the jumper cables or the cables are too light to carry enough current to start the car. Leave the jumpers hooked to the other car for about 10 minutes the try it again. Make sure you have good connections the other car should charge your battery enough to start it in 10 minutes or so. If that don't work your battery may be shot or you have a bad battery cable, loose or corroded connection on your car.

Call the dealer.. They can make a key with the VIN # as long as the car is registered in your name..
