How to change the coolant on your MX5

If you’re taking your first steps into DIY maintenance on your MX5 a coolant flush is exactly the kind of basic job to get you into the swing of working on your MX5 yourself. It’s also something you need to do as part of more involved jobs, including cambelt changes on Mk1 and Mk2 models, and a perfect stepping stone for teaching yourself basic spannering skills.
We've got everything you need to do the job available at www.mx5parts.co.uk

I don’t need to drain the old coolant because it leaked out for me

Hello, I have a mx5 2006 1.8 I just wanted to know after adding the coolant I must bleed the radiator,because I don't know, I opened the reservoir cap, when the engine was cold, but I think that I the air had become trapped in the radiator....😥😥😢😭

Surely always use de ironized water , no matter where you live

[@yei9316]

If you use the carafe sideways (not upwards like this video and most people) with the mouth higher than the rest of it, the splashing will be minimum and you can control precisely the flow of the liquid. Old man trick. The mouth of the carafe needs to be higher than the rest, this way the air comes in freely and there is no bubbling nor splashing. Sorry I cant explain myself better.

What descaled did you use before you drained the car. How long do you need to leave it in there

[@km4026]

What was the cleaner mixture you added in a few days before you changed this coolant

Got me thinking must change coolant in wife's MX5 never been done it's 18yrs old now 😳

[@user-gm7ob3nk3g]

wait is he using tap water ?

[@kanatsizkanatli]

this method is a bit dodgy, doesn't really matter though with mx5s in uk as they are dirt cheap and uk never gets that cold or hot BUT obviously as you saw he only ended up less than than the 5l and the car takes 6 litres, so I think he only replaced about 4 litres out of 6 or about 2 thirds so 1 third I a mixture of coolant or as in his case so chemical gunk cleaning stuff mixed (unknown concentration) with hose water. so if he put in 50 50 mix, the actual mix will be lower

Isn't this the wrong coolant? You need the blue/green stuff in these old engines

[@Meox_YT]

Color doesn't matter, you just need it to be ethylene glycol

[@NicolasCageM8]

@@Meox_YT wrong, it needs to be OAT free, which the red coolants aren't.

for a mk3 it's 11 years or 120k miles NOT every 2 years that's overkill even for a mk1
