Jerry...more then likely the tapered rubber adapter supplied with the kit will be to small for the GV filler neck.

Thanks Hans,

I believe the universal adapter will fit up to 5cm.  If it's to small I'll have to locate a rubber reducer with a smaller hole to fit over the filler neck.

Or disconnect the overflow hose and put your vacuum servicing hose on it. place something under the negative pressure check valve in the cap and just service like that. Just remember to remove when you are done so as the cap can pressurize once again. Doesn't cost anything. Works perfect.

Brett,

What's the difference between the Fleetguard OAT and NOAT coolant and which should we be using?

Thanks,

Rich

NOAT has nitrate added, OAT is what the factory put in mine

If you read clear thru the article in the link below, you will read that Caterpillar does not recommend any nitrate free anti freeze.  If you were confused, and thus asked this question thinking there is only one answer, you may be surprised and will see you are not alone. 

And that includes me.  I would recommend doing your own research, as each mfg makes there own recommendations, and does their own research.

I remember when rv mfgs like Monaco, Beaver, and Country Coach used Caterpillar, Cummins, Detroit, and Navistar engines each rv mfg commented on them only buying one anti freeze for those several engine mfgs.

Three years ago after my research for my Cummins, I decided  on Fleetguards ES Complete, a 1,000,000 mile anti freeze.  Now after your question, I find Fleetguard makes four different ES Complete products, all marketed as 1,000,000 products, in both OAT and NOAT products.  With some being nitrate free, and some not.  I remember Toyota and many other mfgs made a big deal of nitrate free because of their bringing up of the issues with aluminum that they all used. Given my background with Toyota, I believe I installed the OAT product, and I am not sure.  If I cannot find my receipts for the "lifetime" coolant, ES Compleat I installed in 2017, I may see a coolent change soon in my future due to the additions I made when I replaced the water pump.  Thank you for your question.

Confusing at least... All this brings concerns to me because 2 years ago after replacing coolant in my 8.3 and using oat based coolant ie Pm brand, I believe my mechanic added a 16 ounce bottle of Penncool 3000. I have done research and can find a lot of information but can find zero do's and dont's. I can't find who mfg PM extended life coolant so I can call them but did reach Pennray additive who says they will call me back.. All this to try and prevent pitted liners and after reading here it seems we may have done the opposite.. If I can't find an answer today then I will drain coolant and darn well dread that.

Here's a couple of excellent tutorials from Josh ( Adept Ape) on radiator flush and refill using a vacuum refill kit.  This young man really knows his stuff. 

Very easily accomplished with one of these kits and a great way to know if your system has leaks.  No air pockets after refill. This is a must have for us DIYers.

I have 5 vehicles with radiators  and this will make life much easier when coolant flush/change time comes!
