I've never seen it much under 50 bucks a gallon.......I think when we bought it last year it was 46 through summit, so when you said you got 4 gallon for 111, I though you found a steal, But you also said you didn't think that much came out of the motor???
Owners manual says 16 qts. I'll buy 4 gals and if I dont use it will sit on it for the day I need some. Looked up the order and sure enough I goofed. Re ordered the full 4 Gals for 186.00 and got a RMA for the other stuff I'll send back tomorrow.
I hope you guys don't think this waterless coolant is the answer to all cooling problems. If you have problems elsewhere, your temperatures may be higher with it.
I use 15% coolant, rest is water with a bottle of water wetter. Come winter, 50/50 for protection when it sits.... This waterless stuff might work for me , just for storing the car in the off season. Buy once cry once.....Jim
I use a 50-50 mix of the old-fashioned green stuff in all my old junk. All have 15 or 16 psi rad caps, and none overheat or even get more than 190 on the hottest of days, even with the A/C on in the GN. IMO, Evans, Water Wetter, etc are all a waste of money. If they are covering something up, something is wrong, and that something should be addressed. Not to throw a wet blanket on this subject.
Agree Bob, but water wetter is good if you are a racer and prefer to use 100% water. It does provide corrosion protection in that application.
I know for a fact there is no issues with the engine / cooling system that would make it run hot other than its own dated limitations. I can drive on a 95* day 50 -100 miles with the windows down 60-70 mph with no problems. 4 core copper rad., good clutch fan, full factory shroud. Roll up the windows and turn on the A/C (still R12) and make the same run and withing 25 35 miles the temp is up to 225 and will keep climbing. If I dont shut down the a/c and drive until the temp comes down it will boil after I shut it off. I dont have the same issue on a 80* day. Could have used 50/50 in the new radiator. MFG says no problem. Just going this route cause I can. Plan of paying for it out of the company account and writing it off as for one of the work trucks.( For the record the new Tomahawk is going in a F250 super duty! ) hope to have the mods done and the car back on the road this weekend. Also hope we dont have a tropical storm this weekend.
Finished off the project a few days ago. Took all 16 qts (4 gals) +1 for a total of 17 to fill it up to where the factory full mark would have been on the old Harrison 4 core copper / brass radiator. Once I was sure the hearter core was full and all air out of the system put the cap on and let it idle in the shop for 30 mins with the a/c cranking. Never got over 190 on the temp gauge. ( 190 stat) So at normal operating temp the system is full but there is no pressure in the system. Seems strange but since it does not need 14+ psi to raise the boiling point of the coolant.....
So the waterless coolant has been a success so far? Have you been able to drive it under load and see if the temp raises?
I have not had the time to take it out on a long drive. Been hustling around here making last min storm preparations. Supposed to be nice most of today and I think I got everything done that I can do. Doubt we'll get any effects from Dorian but ya never know. Will report back as soon as I have a answer
Saturday I had time to go out for a drive. Used the excuse that I need to buy a new set of sneakers so I jumped in the car and drove to Valdosta which is about 60 miles each way up I-75. It was not as hot like usual but still in the upper 80's low 90's. For that majority of the trip the VDO electric gauge stayed at just a hair above 180. It reads 180 then a 1/4" gap to 200. I stopped after a 30 min run just to look under the hood and it was all dry. Took the cap off and the coolant level was right where I filled it to. Got back in the car and the temp was 220 but came down to 180 ish before I got back onto the highway. Got to where I was going. stopped at 3 different stores and drove home. Rode along at 75 - 80 mph most of the trip with the A/C blowing and during normal driving the temp never exceeded what I would guess was 195 which is what the stat is rated for. Several times the gauge actually dipped down below 180 than came back up to just above. There was 0 pressure in the cooling system during the entire trip. So I'd say the problem is solved. cannot say for sure how much of the improvement is the result of the new radiator and how much is the coolant.
Sounds like a success! So waterless coolant works and offers a extra margin of safety on top of it. To me it sounds like a no brainer to use this stuff and save repairs and boil overs
If you have problems with boil overs and hot running, and you have tried EVERYTHING else to correct it, yeah, might be worth a shot. Conventional coolant works fine for me, so I'll leave well enough alone.
I almost went with this stuff when I built the green car, but I was out of pennies to pinch and opted not to. I've never had cooling problems, but still wish I would've done it back when I assembled the car. Just seems like a good system.
