Coolant additive to increase nitrate level

Bob in Oakboro · Mar 24, 2012

Just did a test strip to check the nitrite, ph, and temp for freezing of my car with a gas engine. The strip shows that the nitrite level is very low. It reads 0 and the strip says that it should be 1600. What do you add to improve this.

Bob, If I understand it correctly, the nitrate additive is needed for diesel engines with wet sleeves. It stops external corrosion on the wet sleeves. On a gas engine, you typically do not have wet sleeves, and don"t need any nitrate additive. Someone will correct me if I am wrong. I don"t think that you have any problem.

Don't worry about it! Nitrate is only a concern with diesel engines (it's needed to control cavitation/erosion on the coolant side of the cylinder liners).

so, would a JD 4010 or 4020 need the additive in the coolant?

While there was not as much of a problem in the 3010-4020 motors, the 219 and 329's had a lot of problems with cavitation. However, JD highly recommends conditioner in all of it's motors. It does work, and isn't too pricey.

thanks, never used it in 30 years. Too late?

Can't hurt. Since I had to rebuild both a 219 and a 329, I'm a believer.

The bquestion is more about corrosion protection. I urge you to replace the coolant at the service interval ( either time or mileage). Corrosion inhibitors are inportant in an engine. I have replaced head gaskets, radiators and heater cores which were corroded through. Hope this helps. Gerard
