A review on your Radiator.

[eamcleod123]

I am looking for some helpful insight into how you rate the efficiency of the radiator in your Mazda mx5.
I am working on a new design, which looks at a new material and a new system but Id like to know if your radiator is causing any problems in your Mazda currently, or even if you have replaced it?

Thank you very much, your comments will help me finish my assignment.

p.s I have received some rather unhelpful comments on this forum, so can I ask that you only reply if you have some helpful insight. Your comments may be referenced in my assignment.

how would you know the efficiency of your radiator without temp in, temp out, ambient air, flow rates etc?

fwiw, i have upgraded to a 51mm core IL motorsport alloy rad. seems to do the jbo well. when all you've got is a temp gauge tho, it's difficult to really tell.

How would I rate it?
I guess I'd create some kind of rig where I could measure the temperature of the inlet and outlet while driving the car, then decide if it was doing a good enough job.

What would I rate it?
1. On a scale of 0 (car over heats), to 1 (car does not overheat).

I have to say your post seems very odd. Most people don't know anything about how efficient the radiator is...why would they? They simply know it either works, or it doesn't. And generally they work.

this looks good , whilst it focuses on air flow you could adapt it to you needs

So even Mazda engineers use PH opinions!

The standard radiator is more than good enough for normal applications. I run a boosted 5 and never had a problem with overheating. My original radiator as just developed a hairline crack in the plastic so I'm about to replace it with a fast 5 alloy rad as they have a bigger core and no plastic bits. I think a bigger problem is the circulation of water through the block. There is a coolant re route that improves water circulation to the 4th cylinder. Take a look on mx5 nutz for more info.

Do you have a link for that coolant re-route info as I can't seem to find it?
