Honda Coolant Joint Tube - D/F/H Series Engines
You're pulling the radiator hose off your Accord or Prelude and you're looking at the coolant joint tube on the transmission side of the head. It's leaking. After 25+ years the aluminum corrodes and the threads deteriorate. Coolant weeps out and you're chasing a leak that keeps coming back. This is genuine Honda OEM part 19500-PT0-000. It's the correct joint tube for D15, D16, F22, F23, H22, and H23 engines. The tube connects the radiator hose to the engine on the transmission side of the head. Comes with thread sealant pre-installed so you're not hunting for the right product or trying to figure out application. Screw it on and you're done. No more leaking. No more chasing coolant leaks that don't make sense.
Here's Why Coolant Joint Tubes Fail
The coolant joint tube sits on the transmission side of the cylinder head where the radiator hose connects. Pressurized hot coolant is constantly flowing through the connection. The aluminum tube's exposed to coolant and heat cycles. Over 25 years the aluminum corrodes from the inside. The threads start to deteriorate. The connection gets weaker. Coolant starts seeping around the threads. At first it's just a small weep. You see a little moisture. The overflow tank stays mysteriously low even though you don't see a puddle under the car. Days go by. The leak gets worse. More coolant's seeping out. You're topping off the overflow tank every week. You're losing fluid constantly. Eventually the leak's bad enough that you're getting an air pocket in the cooling system. Air in the lines means hot spots. Hot spots in the engine mean high temperatures. You're getting warning lights. The engine's running hot. You're wondering what's wrong. The joint tube's been leaking coolant for months and contaminating the system with air. Replace the joint tube before the cooling system gets compromised.
Thread Sealant's Already There - Just Install It
This joint tube comes with thread sealant pre-installed on the threads. You're not ordering a tube and a bottle of sealant separately. You're not trying to figure out how much sealant to apply. You're not wondering if you applied it right. It's already there. All you're doing is screwing the tube onto the head. The sealant's doing the job. No mess. No guessing. Direct replacement.
Replace It When It's Leaking - Don't Chase Your Tail
If your joint tube's leaking replace it now. We've seen people spend weeks trying to figure out where a coolant leak's coming from. They're checking the water pump. They're checking the radiator hoses. They're checking the thermostat housing. They're bleeding the air out of the system over and over. Nothing's working. The leak keeps coming back. Then they finally look at the transmission side of the head and see the joint tube's been weeping the whole time. That's where the leak was. All that time wasted chasing a leak that should've been obvious. Look at the joint tube. If it's wet or crusty from dried coolant replace it. If your cooling system's constantly low and you can't find the leak, the joint tube's probably the culprit. Don't waste time bleeding the system if the joint tube's leaking. Fix the leak first.
Honda OEM - The Right Part For Your Engine
This is genuine Honda OEM part 19500-PT0-000. It's the joint tube Honda installs on D-series and F-series and H-series engines at the factory. The aluminum's the right alloy so it doesn't corrode as fast. The threads are the correct size and pitch. It fits correctly. It seals correctly. Aftermarket joint tubes are out there. Some are fine. Some are cheap knockoffs. We've seen aftermarket tubes with threads that don't match perfectly. The tube screws on but it doesn't seal right. Coolant leaks around the connection immediately after installation. We've seen cheap aluminum tubes that corrode faster than the OEM tubes because the alloy isn't as good. We've seen aftermarket tubes that come without sealant pre-installed so you've got to apply it yourself and hope you do it right. The coolant joint tube is handling hot pressurized fluid at a critical connection point. It's not where you cheap out with an aftermarket knockoff. Buy the Honda tube. It fits. It seals. It lasts. You install it once and you're done dealing with this leak.
