Cooling Pro Radiators

How long did they take to install? Mine is still sitting in the box, from memory last time I swapped stock ones over it was an annoying job, though that might have been because the first replacement ended up being cracked on the bottom but didnt notice that until it was fitted and filed with coolant...

if it's taken more than 30 minutes then it is a major FAIL.

It should just be: Flush Radiator, take off undertray so easy to get to, Unclamp hoses, take off fan, uncsrew. Take Radiator out. Then reverse of that

You shouldn't need to take off the undertray, you can reach all the hoses from above to unclamp them from the radiator and there is a gap in the undertray for the drain plug
just draing, undo clamps, take off uper mounts, unplug fans, remove radiator + fans, swap over fans, put radiator back in, attach fans, attach top mounts, put in hoses, refill.

you would prefer to reach in and undo the bottom radiator hose clamp from above?

not sure about the NA but the NB has a flap which you just unscrew then you can reach the bottom radiator hose clamp

Hey does everyones radiator fan keep spinning after the engine is turned off?

Mine turns off instantly as soon as my engine stops running even with the key turned to ON it doesn't spin

I know other cars keep spining but its not an MX-5

oh yeah i forgot about that little flap!

i was wondering the same thing about the radiator fan just the other day - i thought it was strange that the fan in my NA8 doesn't spin without my engine running either.

My son fitted a cooling pro radiator to my mx5 an NB.

As for it being a straight fit with all mounting holes lining up, haha.

The judicious use of a hammer was needed.

Good price, does the job, not sure though if I wouldn't go a bit more

upmarket next time. You get what you pay for I find.

the earlier cooling pro's were a bit dodgy , fitment wise, apparently. but the curent ones are meant to be a-ok from all reports. mine certainly did fit without having to modify any mounting points etc...

altho yeah... it's still a cheapy radiator and i have my doubts it would be up to the task on a really high power modified car. it's doing it's job on my car tho, no complaints here.

Money aside I'd go Koyo; the PWR one I had in my NA required more than a hammer to fit. Had to drill new holes in the fan mounts!

According to MX5 Mania, the first series of Cooling Pros, had issues with mounts/hole mis-alignment. Apparently Mania sent several examples to the manufacturers to prove this (I was told the manufacturer didn't believe this was the case at first), and have since been fixed. So if you buy a new one now, there should be no issues with fitting.

My NA8 has a cooling Pro, no complaints so far.

I put my cooling pro in yesterday, a pretty straight forward job although it took me a while and was a pretty tight fit. The only problem I had was the pins that hold the rubber bushes that hold the bottom of the radiator in place are too short for the cooling pro (being a fatter radiator). I had too make some new ones up out of some bolts.
The fan holes were a perfect fit.
