Title: Samurai factory radiator able to cool a toyota 22R?
Post by: dnbuggy on July 29, 2011, 11:26:01 AM

I have a 22r in my 87 sami and it keeps getting really hot.  I have an aftermarket fan installed, but still when I am in stop and go situations, it get's up to 210-230.  I have the sami original radiator in it.  Wondering if this radiator is big enough to cool the 22r?  It's possible the radiator I have is toast and I need to replace it, but just wanting others thoughts first.

Thanks!

I have never been able to find a suitable electric fan from an
auto parts store, I think the OEM stuff available at the wrecking
yards are better at cooling, but on a second note, the Samurai
radiator is a bit small for a 2.0 + engine, so you might need to
get something with more cooling rows to help cool it down, this
would be more true if it were over heating at speed or load, but
stop and go should not be as much of a problem, look at the temp
switch that activates the fan, is it working? where is the heat signal
taken from? the block or the hose?

Stock Sami= 1.3 L to cool. 22r= 2.4 L. That is 1100cc to make up for. You would need one great Samurai radiator.   I would go for a custom made unit in the stock position that has at least 4 rows.  Talk to a good radiator man and they should be able to fix you up. If you go aluminum, the options are limitless and pricey. I agree with Wild on the electric fans. I have even found factory electric fans to perform worse than factory direct drive fans (in at least one case).  Good luck

I have a 2.0 Honda engine from a 80's accord has duel electric fans.  I was doing something else with this project and bought a new radiator for 100 bones.  I am considering fitting this in a sami but I have not even pulled out a tape on it yet.

also note; whats Toyota normal operating temp? normal operating temps have been creeping up for years.it is a method of keeping cylinder temps up and scavenging fuel economy. I do remember seeing a car recently that had a 210 degree temp for the low side of its temp range!  :o

I know Brent at trail tough uses nice aluminum radiators in the 2.0L swaps, that might be a place to look.
