I finished building my 1.6 this fall and installed a decent "automatic" radiator which has worked good in fall and winter temps. Will I need an upgraded Alum. one next year or did the old ones work pretty good back in the day? Just planning ahead. Which brand, if I need to buy?

I cannot tell you if you really need the aluminum Rad or not, I have one and it works fine. my first one was the Koyo its pretty good but pretty expensive. When I toasted that one from a wreck, bought a Godspeed on EBay and its about 100.00 less expensive and works well.

yes, you will want to upgrade.

Koyo 53MM or Sprigfield Dyno Rad.

I have had really good results with my cxracing rad. It is basically like the koyo. 53 mm, and comes with a cap. I believe it was 150 duckets.

How do I fit this ls7 into my mia... nevermind.

The OEM auto radiator does a decent job cooling. We ran it for hours straight when it was mid 90s at the track. We tried a stock manual one that overheated early in practice. On the other hand, we had really long straights and it was a chump car race so not much drafting. It's nowhere near as efficient as my big Koyo but we were limited to what we thought we could get away with. [Smile]

+1 on the CXracing aluminum radiator. I have been using and abusing it in the scorching Texas heat this season and it has held up perfectly so far. And less than $150 shipped.

+2 for the CX radiator. Temp stays at 192 with the stock thermostat regardless. Even my oil temp has been lower-205 instead of 220.

If you can't fix it with a hammer, it's got electrical problems.

[twocents] If you are down south, I'd say you need a larger radiator as 1.6Ls don't like heat at all. I have the big Koyo and it's been great.
