Description
There’s nothing worse than starting a coolant change and discovering your drain plug is stripped, missing, or won’t seal. Instead of wrestling with makeshift fixes or watching coolant drip all over your shop floor, this replacement plug gets the job done right. When you’re trying to maintain your cooling system between busy seasons, having the proper drain plug makes all the difference.
Key Features
- Direct replacement for original equipment – no adapters or modifications needed
- Precision threads ensure leak-free seal without over-tightening
- Hex head design won’t round off like cheaper plugs
- Corrosion-resistant construction handles years of heat cycles and coolant exposure
- Machined sealing surface for consistent, reliable shut-off
Built for Real Farm Work
This plug fits the radiators used across multiple John Deere series – from the versatile 6000 series utility tractors through the larger 6010 lineup and into the 7010 series machines. Whether you’re running a 6400 on the loader, a 6610 in the hay field, or a 7510 pulling heavy tillage, regular coolant service keeps these workhorses running cool and reliable.
Made to Last
A radiator drain plug lives in a tough spot – constant exposure to temperature swings, coolant chemistry, and road debris. This replacement uses materials that resist corrosion and maintain thread integrity season after season. The hex head is built to handle removal tools without stripping, and the sealing surface stays smooth for consistent performance.
Good to Know
Before installing, clean the radiator threads thoroughly – old sealant or debris prevents proper sealing. Apply a thin layer of thread sealant but don’t overdo it. Tighten snugly but avoid excessive force since radiator tanks can crack under stress. This is also the perfect time to flush your cooling system and check coolant condition while everything’s drained.
