Finally - A Cold Fix

dieselpwr · Mar 10, 2001

Good news for all of you who have these cool running Boomers. When my TC45D was in for the tranny recall they also took the time to figure out what the cause & fix was for these things not warming up fast enough... or just plain warming up enough in the winter. It turns out that they needed to install an additional valve in the hose with the coolant drain valve. The additional valve allows the flow through that hose to be turned off, thereby allowing the thermostat to do its job. The coolant can no longer bypass it by going through the drain hose & through the radiator & back into the block again - all nice & cold. It has to stay in the block until the thermostat opens now. My machine now quickly comes right up to operating temperature & stays right there. Just an FYI I was told that they used a fuel shut off valve from Briggs & Stratton that happens to fit the hose perfectly. My dealer did it as a customer satisfaction thing free of charge, but if yours won't, it is a cheap & easy enough fix to do yourself & it should keep your machine running longer & better at the right temp.

Sounds like you have a good dealer. Someone who stands behind you. Good news fixed at no charge./w3tcompact/icons/smile.gif

There are many of us who NEED this fix for our COLD TC's.
New Holland should take responsibility to fix ALL of our engines, not just a case by case fix by the dealer. It is NOT right
that so many owners are resorting to cardboard in front of their radiators. I am glad you got a fix but the rest of us need to
call our dealer today and demand that they ask NH for a fix for all of us. This should not be just a "customer satisfaction
thing". It is a defect that NH must acnowledge and supply a fix that is compatible with our warranty.

Troy,
Do you have to turn the valve on/off? When do you want it on and when off?

The valve is left in the off position all the time to keep the coolant from bypassing the thermostat. The only time you need to open it is for draining &/or flushing your cooling system (as well as filling it back up).

Troy - reactivating a "dormant" thread here...

I just bought a TC33D. Saw your post aboout the extra valve to solve the "cool running TC's". Did this problem exist across all models, or just the larger TC's? I live in Vermont, and am wondering if I need some modifications made before winter comes.

Do you know if NH ever implemented a fix on their production line, or is it still an after-the-sale, case-by-case basis?

Thanks... John

I don't know if it affects the smaller units or not. I know it affects the 35, 40 & 45 models though. I don't know if yours would have the same design flaw or not. The tell tale sign is if you have 3 hoses going from the block to the radiator. (2 large primary hoses & the problem hose => 1 tiny bypass hose with a petcock for draining the system) I don't know if NH ever addressed the problem or not. I do know that mine comes up to temp. quickly & stays right there now. /w3tcompact/icons/smile.gif

John, I think that was a problem with the larger models. I have your smaller cousen (TC29D) and the machine comes right up to temp in Michigan winters. I run at 1800 to 2000 RPM when moving snow.
