hey i have the red coolant in my truck and i dont know if the addative has been added or what. Where can i get the test strips at? also how much do they cost? are they easy to use? thanks

 

I am using evans waterless coolant system. It requires no additives ever and it last for 500,000 miles or so. Do a search for it.

MotoX

 

Your truck is a 99 so it should of had green coolant. The red or gold coolant is extended life coolant and is not compatble with the seals in that engine. You need to flush your cooling system, get low silicate antifreeze and FW-16 additive.

 

Hey i bought valvoline max life antifreeze. the liquid is green and its in a red plastic container.. Is this kind ok?

 

I don't know. I know that Quaker State and Zerex G50 are ok.

 

sorry its not valvoline. its zerex max life antifreeze. it says on there thats it can be used in a cummins.

 

No max life coolants to be used in your truck

 

When I changed my coolant I didn't relize the PSD was so picky, and I put the wrong stuff in it... I drained out the new coolant, researched the recommended specs, and put Max Life , made by Valvoline in it with FW-16 additive. According to their Web site, Max Life match recommended specs...I'm not going to drain it again ...

 

ok cool thats what i have but i dont think mine has the addative in it but im gonna buy it from ford. thanks!

 

does anyone know what seals are involved and what it would take to replace them ? i have had the red coolant in for 2 years and everthing seems to be holding up. F250 born july 98.

 

Does anyone know what kind of coolant is a 01' PSD? It is getting to be that time to change mine and I don't want to buy the wrong kind. Also what is a good brand to get?

 

I got 10,000 miles on my evans waterless coolant so far and i dont think it would hurt your seals. Read up on it. https://www.evanscooling.com/main23.htm

I dont have any affiliation with them i just didnt want to go through the hassle of deciding what to use and adding sca`s all the time.
