I hope your right ankle is in great shape!

It is lol I know part of me wants big american luxo barge but I'm too tall last time I traveled it was in a 90 Cutlass ciera and laying across the front seat got a little bit cramped. Plus starter died fuel injector went out lol 🤣 lots of lessons learned on what vehicle is perfect for never being stranded. And I'm putting an rx7 gearset in it for better gas mileage. How would I go about starting a thread on my build just Jerry c's build or Start a thread in a certain spot?

I finally got the CSF 2 row radiator

. I will install it today will update you with the results.

I installed the new radiator and still it overheats. I replaced the coolant and let it idle for about 45 minutes with the rad cap off. I rocked the truck side to side occasionally while it was idling to let the bubbles out, but still it goes past the halfway mark on the temperature gauge. However, I did notice that lower radiator hose is actually cool to the touch while with old radiator it was lukewarm, so I think the CSF is doing a better job at cooling. I think I will let it be for now untill I get some funds to take it to a shop where they can do a coolant system flush. Im thinking maybe a small hose somewhere got clogged? Here are some pictures:

Coolant flow diagram attached. To me sounds like the radiator is working, you say lower radiator hose is cool. I had read that the temperature gauges in the clusters with tachometer read higher than the non-tach clusters, from those who've just done a cluster swap. Besides, your gauge reading in your photo (above) is within the limits, so this does not show "overheating", within the acceptable range. Have you tested the sending unit for the gauge?

Hey Cusser, this is a swapped gauge cluster from a different truck. This whole truck is a frankenmazda haha. It's a 86 b2000 with 92 B2200 wire harness and EFI swap. Maybe thats the problem?

When I had an old radiator in the truck, it would sometimes go up the letter H and sit there, so hopefully, with the new radiator it doesn't go up that high. I swapped sending units before and it showed the same results. Maybe I'm just over stressing it and should leave it alone at this point.

Hmmm - when you changed to an electric fan, did you keep the fan shroud? Or are you running without one? Fan shroud is important.

I had a shroud when I was using an electric fan. I'm using the stock clutch fan with a stock shroud now.

Good.

What thermostat are ya running?
