Title: radiator mod for larger 22r engine
Post by: dnbuggy on August 26, 2011, 04:56:53 PM: 87 sami w/ 22r engine. I am having trouble cooling with the larger engine with the factory radiator. With the larger engine, there was no room for the clutch fan or an electric fan inside the engine compartment. I Put an electric fan on the outside, but still not enough cooling for low speeds. My plan is to put a radiator inside the space where the grill is. I have about 14 7/8 H x 20" W (I could maybe push this to 24" W) to work with. This will allow me enough space to go with a factory clutch fan or an electric fan inside the engine compartment. Problem is this: I can't find a reasonably priced radiator to fit that space. I know there must be a small 2 or 3 row radiator off a car made in the last 30 years that would work, I just can't seem to find it. Any ideas?

I think if I go back to a sami rad, but one that is multi row or aluminum with an electric fan, it might fix the problem. Thanks!

water wetter does work, not as well with antifreeze as it does with straight water, but it could help.

I have seen lower temps when running Honda coolant vrs the Prestone stuff.
