Odd oily feeling red substance in coolant. Doesnt smell of oil. Put in a used engine from a wrecked car and found this substance after filling up coolant and running engine for a half hour or so. Oil level has stayed constant and it runs fine, though havnt taken it for much of a drive. Wondering if this is somekind of sealant or wetter mayber?

 

That sounds like transmission fluid that someone used to unflood the car or something. It could be that the o-rings are starting to wear. It couldn't be Water Wetter, as WW mixes w/ the coolant.

 

Was the engine from an automatic vehicle. The tranny fluid runs through the radiator bottom. It could have cracked and sucked the fluid into the engine just prior to shutdown after the accident.

Only other red fluid might be power steering fluid and it is not anywhere near the engine cooling system.

The oil inside the radiator fluid should not affect it too much, just need to get it all out as soon as possible.

When I stored my motor and turbo, I filled them with ATF fluid.

The turbos were submerged in ATF fluid. Maybe this is what the junk yard did to protect the motor.

 

I think the best thing to do is to just flush the cooling system & check it again after a while. It's a used engine from a wresked car; who knows what the prev. owner did....

 

Aye, was from a auto. Ill flush the system today and see what happens.

Thanks for the replys.

 

Ah, I assumed you had a manual tranny. As mentioned before, it could have been due to a bad radiator (auto trannies usually have a tranny cooler built into the radiator). I have seen this happen on a few cars before, you can either bypass the stock tranny cooler and replace it with something from B&M (or another manuf.) or just replace the entire radiator assembly itself...this is if flushing doesn't help.
