I'm interested in the idea of putting a coolant filter in a 22re cooling system. Certainly unnecessary, but fun to think about anyway.

My question is how would one integrate a coolant filter in the cooling system in a bypass configuration? I don't think you would want to put it right in a main line since it could impede flow and cause problems if it blocked up. Basically, where would you put it in the coolant flow path?

 

Perhaps the heater core lines?

 

Commonly, it's spliced into the throttlebody coolant line. However, the cars I've seen it on did not have coolant actuated idle speed on cold start.

I'd say put it on the return side of the TB coolant lines and call it a day. You will be surprised what that filter picks up!

 

just to beg the question, why, if you clearly state that it's unnecessary, would one do this anyway?

 

Good idea on the coolant lines, it would probably be an easy place to access the filter too.

It's purely academic, superbleeder.

 

itd be interesting to put a clear inline filter and see what happens. perhaps some rtv floaties..

 

Only issue that may come up is the blockage of filter. I would definately put a filter on, but how would it be bypassed as not to cause oeverheating on a real dirty engine? Is there a see throguh filter avaialble like a fuel filter so you can see the junk?

 

I have seen see-through filters offered and they can be placed inline with the main coolant flow. But they just have little mesh screens to catch big pieces.

I'd definitely start fresh with new coolant before installing a filter.

Part of why I'm interested in it is so I can run some high-quality coolant like Amsoil and leave it in there for a long time. I know someone will chime in and say "why don't you just use the cheap green stuff?" The chemistry aspect is important as far as how quickly coolant tends to erode aluminum, steel, gaskets, silicone sealer, etc.

 

As I stated before, you will be surprised what is floating around in even the cleanest cooling system. A coolant filter is a very good idea.

We're not talking about a small, clear, easy to clog filter. They very much resemble an oil filter, but for your coolant. Do it.
