JerryB Posted February 23, 2010 Share Posted February 23, 2010 when I figure out how to post it I'll post a picture of my "coolant pushing" cure. After putting a new waterpump and housing on mine it started pushing coolant again. I had the cylinders and heads checked and they found no problems so we didn't know what else to do.I went to the boneyard and got a 2.5 gallon steel coolant reservoir from an older Western Star because it is round and looked easy to modify the reservoir brackets on my truck to fit it. When I installed it I only filled it halfway with coolant to leave room for whatever and put a new 7 pounds pressure cap on.So far on 5500 miles or so it hasn't lost any coolant and never over pressures the 7 pounds radiator cap. I've been driving it like it belongs to my mother in law and I'm mad at her. damifino why but I think it's fixed.

JerryB Posted February 23, 2010 Author Share Posted February 23, 2010 Ya be careful! As For Jerrys coolant jug I thought you had the big round aluninum tank on there already!No on the tank, they kept being on back order at Mack so we put the update thermostat housing and bottom radiator hose and static fill hose on but left the old jugs in place. HK that might help too so thanks for the idea Quote Link to comment https://www.bigmacktrucks.com/topic/12751-fjh-and-bigen/#findComment-50121 Share on other sites More sharing options...

cgallamore Posted February 25, 2010 Share Posted February 25, 2010 i should have known, as soon as i got rid of mine, you would figure it out. guess it would have saved us both some money, if i had got rid of mine sooner Quote http://www.bigmacktrucks.com/uploads/1272400769/gallery_4852_794_314995.jpg Link to comment https://www.bigmacktrucks.com/topic/12751-fjh-and-bigen/#findComment-50243 Share on other sites More sharing options...
mackdaddy1911a1 Posted February 28, 2010 Share Posted February 28, 2010 My truck has "pushed" coolant since day one but not to bad. The problem is the radiator cap doesn't bottom out on the neck of the filler tube. One day I squeezed the hose from the top tank to the engine and at the same time watched the coolant in the bottom tank ....and what do you know it moved. That tells me that on a cold engine that the cap isn't sealing off the reservoir from the over flow"bottom" tank. There for the coolant flows nearly unrestricted from tank to tank as it heats up. I guess it either overflows due to outtage when it's hot or it evaporates. Anywho I only have to add a gallon every week or so and replacing both tanks and a new 10 pound (from mack) cap didn't help so I just live with it.A design flaw that the Smart people missed even after I e-mailed them about it. P.S. I have also had the modified pipe and hoses added and have never had the truck over heat even out in the mountains of Arizona pulling 48000 pounds of copper up and down those 6 and 8 % grades.
