Coolant

Costs nothing and takes about 30mins...do it yourself you lazy monkey!! :p

 

In all seriousness its really easy to do, but if you want to pay someone else if it takes more than an hour they shouldn't be near the car to start with.

 

Most garages have a general hourly rate. Phone them to find out what it is. Toyota themselves should be about £50 an hour.

Nope not I never been...

 

There is a tap on the bottom, passenger, engine side of the radiator which you can open to release all the fluid...or if you're like me and can't wait....undo the rad cap, remove/loosen the under tray and yank off the bottom hose. It will p1ss out of it from there...but will still take 20 mins to drain fully. Then reverse the process and add coolant (Toyota 4Life Red) once it's getting full slow down pouring it in to allow air to escape...fill to the brim, empty your expansion tank and fill it to the max line. Put all the caps etc back on. The bottom rad hose is on the drivers side.

 

Run the engine till warm, making sure you've got the heater on in the car. Then shut off and leave for about 5-10mins to cool and de-presurrise (DO NOT EVER ATTEMPT TO REMOVE THE RAD CAP AFTER JUST SHUTTING THE ENGINE OFF). Once the rad is cool enough to the touch you should be able to open it up but do it with care. Once open just check to see if it needs topping up. Take her for a run and check again after that. You'll probably hear the odd air lock go through the heater matrix in the dash.

One addition - It is best to fill your coolant from the hose at the back of the motor. If you fill it through the radiator cap you will likely have bubbles. Filling it from the back gives you a much less chance of air pockets.

 

I start the car and let it warm with the radiator cap off while filling up from the rear of the motor. This helps remove any air pockets while filling.

 

Regards,

Thats a quick way to change about 3/4 of the fluid , there is also a tap on the rear of the block under the turbos , this is the block drain , otherwise the block stays full of the old coolant !!!!!

Now is also a good time to flush your matrix if you think the heater is not as hot as it used to be , flush it both ways to remove any sludge or even better do that and before you start put some flushing agent in the rad and run the car a while , now is also the time to change the stat if your in doubt :thumbs:

Dustys right , some cars can be a pain to bleed some are dead simple , another trick is to use a coke bottle , cut off the bottom and use it as a large funnel , wedge it in the rad and fill it to the top so it has some 'weight' pushing the coolant into the rad , periodiclly squeeze the top and bottom hose and repeat untill no bubbles are seen in the bottle , i got fed up with this and bought a neat tool that sucks all the air out of the system cerating a vacuum , you then open a tap and suck the coolant back in leaving no air in the system .

BTW dont forget to leave the heater on hot when doing this ;)
