For the longest service life and best reliability, silicone radiator hoses are king. Here is how I installed these on my car.
Step 1: Removing the Old Rubber Hoses.
My old hoses use hose clamps to keep them in place. The rubber actually bonds a bit to the metal Coolant ports. Getting them off takes some hand work. Once off I put them aside with the hose clamps. Those clamps cannot be used with silicone hoses.
Step 2: Installing the New Silicone Hoses.
This hose combo I got off Amazon.com for my Honda civic 1999. It cost 75usd. Tbolt clamps are needed and were purchased separately off Amazon.com.
The new hoses slipped on easily and the clamps were used to secure them.
Step 3: Filling Coolant.
I filled the reservoir then the radiator through the pressure cap port. Once full I started the engine and let her idle till the fan came on. I kept Topping off the Coolant in the radiator then put the cap back in place once no more could be added.
Step 4: Completion.
While the car was running I carefully monitored for any leaks. None were detected and I'm pleased with my work.
Now my car has new silicone radiator hoses that should given me long service life!
