MX5 radiator Change


Sunday morning my head didn't hurt that much, the sun was shining and so I thought it would be the perfect oppurtunity to get some fresh air, get the tools out and swap the radiator on the Eunos Roadster as it was leaking along the top core.



Now I was a bit worrid about how to do it, due to the fact the air conditioning is attached to it. Now its not explained in the Rod Graingers Manual but there is some info in the Hayes manual for a change.



So remove air pipe, the fan wiring, the air con fan wiring and the breather hose from the top of the radiator. Remove the undertray. Then either side of the radiator at the top there is a bolt to remove.



You cannot see the bolt on this photo so pretty pointless but down the side of the radiator they lie and you will need a socket wrench to undo them.



At the bottom of the raidiator there is a drain plug for the collant. So use it to let the coolant out!



Next remove the coolant hose from the top of the radiaor



With thetwo bolts removed the raiaotr will be free at the top.



Next remove the bottom raidiator hose.



Next the air conitioning pipeowrk requires to be removed from the raidiator. This is held onto the raidiator in two places with bolts.



These bolts are one of the four bolts holding the fan in place for the two fans.



Remove with a spanner



and this one as well.



Move the brackets out of place and the pipework.



This should now leave the raiator free to be lifted out of position.



And here is the raidiator removed.



As we can see here the air con is left in place and is not connected to the radiaitor.



The air condensor is fitted directly onto the body of the car.



New radiator from MX5 parts. An exact copy and match. But needs the fittings and fans mving across.



The fans simply unbolt and then bolt in place on the new radiator.



Here is one of the two moutning pins that need to be moved across. To take off the original radiator you need to remove the circlips with a small flat bladed screw driver.



And put them somewhere safe.



And the bolt hole rubber mounts need removing from the old radiator


.


Push the metal washer out



Then pull out the rubber ring sidewards.



Give it a good tug.



Then simply slip them back in on the new radiator.



Enusrue they are in the correct position and



put the metal ring in place.



Now put the pins in the new radiator and push the circlips in place as shown above



All done it now as the haynes manual says installation is reverse of removal.



Once installed, top up with water and antifreeze, and if possible do this with the front end raised to remove air locks quicker. Run the engine until warm. Allow to cool and retop up. All done and time for a cup of tea.
