i did all that already. i have another thread in the powerstroke forum that is getting moved over here. i also added the electric pump.

 

no the only way to check is to do a pressure test on the cylinders i know the most prone are i believe 4,8,2 and i believe maybe 1 other somone else will know but you can do a pressure test and it will give you a 100% answer the test strips are just gunna tell you if the po kept up with the sca if it test good on the sca level then dont worry bout it cause the po kept it in check if it test no sca or a few then you can pray or do a pressure test but since you have it know no matter what go ahead and change the coolant out and put in the cat or another one you like and change it every 2 or 3 years and you will be good just be sure what you choose is premixed with sca or you can add them yourself i like it premixed better

 

dumb question, but here we go: if the PO drained and filled the rad shortly befor i got the truck, would the test still be accurate?

 

well what is the coolant in there is it the reg green coolant if so then yes cause the reg green coolant has no sca he would have to have mixed it in with it and i rally doubt he would have know about it right before he sold it if he had never done it before

 

i really havent looked. by the time i found out about this, the engine was to hot to pull the cap, then i popped open a beer...

 

check the oil for collent

 

If he drained and refilled the rad., and the system had sca's in it, your test would show the sca's to be on the low side.

 

Remember, sca's will not repair cavitation, but as soon as you start useing them the cavitation should not get any worst.

 

i can get these test strips at napa?

 

ya napa has them and napa might have sca addaditive and joe is right you can also smell the exaust it will smell sweet if it has cavatation and if you like easy fixes and simple cheap parts the idi is perfect easy to fix and simple to make more power out of i mean a turn of a bolt and you got ip injecting more fuel thats cheap power there lol

 

Depends on what sca's are in the system. NapaKool is dca2, fleetguard and Ford use dca4. the two are not compatible and use differrent strips.

 

get both? do i have to get the additive to get the strips?

 

Or a blown head gasket

 

well ya but the best way is pressure test for cavatation the oil will tell but to figure out which cylinder you will have to pressure test anyway so if the thought concerns you by a kit and do each cylinder and pray while you do it

 

i found a local shop that will check my injectors for free. so here iam pulling them, i got 4 out on the driver side and they go CODE D, BB, BB WITH NO COPPER RING, E. I havent got to the pass side yet.
