If anything, removing the thermostat will make the engine run colder and very slow to warm up. The cooling system is not largely dependent on the speed of coolant running through it nor the time it has to transfer heat to the radiator. I think that misconception comes from the fact that most people remove the t-stat because they have cooling system problems to begin with.

It will also cause the ECU to stay in open loop longer(or permanently) and it will reduce fuel economy, increase wear, oil contamination, and possibly sludge formation.

 

A while back I was talking to a guy I worked with...his father-in-law used to race stock and modified at the local track. They had to run restrictor plates to keep them from over heating...I figured the same held true here as well. I could be mistaken, I my self have not run without one.

 

I found a forum entry on another site a while back that thoroughly explained why the coolant can't really "move too fast" through the radiator, but I'm having a heck of time finding it again. I thought I saved it, copied it, bookmarked it, etc.

 

how's it doing a year later?

 

I used one of the can repairs last year in my '92 22RE. It worked-for awhile. My HG leak is external so I just lose coolant slowly. Anyway, the leak is back now.

 

tnx, I'm gonna give it a try, I've got a new engine, so with 180k on a 22re with a blown head gasket with white smoke and antifreeze in with the oil, Nothing I can really ruin that a new engine won't fix or that a rebuild (which I plan to do slowly on the replaced engine) won't fix. sorry to specify so much but I want ppl to be able to find this in the threads easily. Tomorrow will start the test and I'll report back tomorrow afternoon.

 

well did it work?

 

well for the cost I decided to just rebuild the head, like $150 worth of material. I sold the 4runner though so someone else is rebuilding the head, so sorry but IDK.
