Product Details

The Mishimoto MMHOSE-GM-23U is a high-performance silicone upper radiator hose engineered specifically for 1966-1968 Chevrolet Impala models equipped with 283ci or 327ci engines. This premium replacement hose provides a direct-fit upgrade over the original rubber radiator hose, delivering superior heat resistance and durability for improved cooling system performance.

Key Features:

  • Five-layer silicone construction with heat-resistant embedded fibers for maximum durability
  • Significantly improved heat and pressure tolerance compared to stock rubber hoses
  • Direct OEM replacement fitment for 1966-1968 Chevrolet Impala with 283ci or 327ci engines
  • Available in sleek black finish to complement engine bay aesthetics
  • Includes high-quality stainless steel worm-gear clamps for secure, leak-free installation
  • Resistant to coolant degradation, extreme temperatures, and pressure spikes

Mishimoto's premium silicone radiator hoses are designed to outlast conventional rubber hoses while maintaining flexibility across a wide temperature range. The multi-layer construction provides exceptional burst resistance and prevents the cracking, hardening, and deterioration commonly seen in aging rubber hoses. This upper radiator hose is an essential upgrade for classic Impala owners seeking reliability and improved cooling system performance.

Relatively easy process

So far so good, best price I could find that actually had the part in stock

It worked.

great

Overall good transaction had to go through PayPal to make the purchase, wasn't allowing me to use card info.

Love the Amazon pay option. Best price I could find on the net was through autoplicity. Great service thus far.

Very good deal and simple buying experience.

Super easy + best price on the web. Very pleased am I.

I am very, very satisfied with my order. I ordered a Tonneau cover. It was a 35 lb. package and there was NO shipping cost to me. Plus it was received 3 days after my order. I searched many other websites and Autoplicity had the best pricing.

Good price, amazon checkout simplified whole process.

I was very pleased with the way my order was handled. I will definitely use them again.
