Silicone Radiator Hose Kit for Dodge Charger Coronet (1968-1973)

High-Temp Silicone Radiator Hose Kit for 1968-1973 Dodge Charger, Coronet (B-Body)

What it Does: The Silicone Radiator Hose Kit replaces deteriorating factory rubber coolant hoses on 1968-1973 Dodge Charger and Coronet models to eliminate cooling circuit blowouts and withstand high-thermal operating pressures.

The Stock Dodge Charger, Coronet Cooling Degradation

Original equipment EPDM rubber coolant hoses on vintage Chrysler B-Body platforms suffer catastrophic breakdown over time. Constant exposure to extreme underhood engine temperatures, oil contamination, and internal hydraulic cycling causes traditional rubber to turn brittle, expand, and develop microscopic fissures. In classic big-block and small-block configurations, electrochemical degradation (ECD) erodes factory hoses from the inside out, weakening the wall structure until pressure spikes force pinholes, bulging, or complete hose separation at the radiator neck.

The Engineering Solution

Engineered as a direct-fit replacement for stock cooling routing, this kit is constructed from multi-layer reinforced silicone featuring a 3-ply polyester fabric weave and a substantial 4.5 mm wall thickness. This construction resists oil degradation, ozone exposure, and temperature extremes ranging from sub-zero conditions up to 350°F+ without hardening or ballooning under cooling system pressure. Included stainless steel worm-drive clamps deliver uniform radial clamping force along the junction beads, preventing coolant weepage and flange damage on both aluminum and copper-brass radiators.

Frequently Asked Questions & Fitment Warnings

Does this fit the B-Body Charger, Coronet?

Yes, this is a direct fit for the 1968-1973 Dodge Charger and Coronet utilizing stock radiator inlet/outlet locations across standard V8 platforms.

Do I need to bleed the cooling system after installing these hoses?

Yes, after seating the silicone hoses and torqueing the supplied stainless clamps, refill the circuit with your required coolant mixture and properly burp all air pockets to prevent hot spots.

The Dodge Muscle Standard

Mopar big-block and small-block powertrains demand cooling integrity that handles high RPM thermal loads and heavy stop-and-go torque generation without blowing lines off the water neck.
