Hey guys

Quick question:

I just tested my coolant with fleetguard test strips and it showed my sca level at 0.0. I bought two pints of the correct sca additive and was wondering if these could be added to the radiator without doing a complete coolant change? The coolant looked clean and clear.

Come spring I plan on doing a complete coolant drain and flush. right now it's just too darn cold for that. Just thought I would ask before tried it.
Thanks.

 

Sure, you can add the the SCA. I assume either the test strip jar or the SCA jug will tell you how much to add.

Drain out some coolant, add SCA, top off.

if the coolant in there now is "low silicate" you can add the sca's.if the coolant in there might be standard green but not a "low silicate" then you can't add sca's to it,or you'll end up without sca protection plus sludge.

 

it is most likely low silicate coolant, two pints will be just right, or you could drain and flush and install fleet charge, precharged coolant not fleet guard, wrong stuff,
