    CHR621N is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from Fast Shipping & Premium Product Ordered late March and arrived super fast! I am so pleased with how quick I got this. I read a ton of reviews and product guidance before ordering as my cast number was 4983298 and this product stated the cast number to be 3977225/3977221. Product arrived safe and sound via a reputable carrier. It was packaged up nice and careful. Absolutely no damage to the crate during shipping. Popped this right in with no issues other than your standard 'its a tough kinda job" frustration. Absolutely no fault of the product. Loved that there was no core charge and JEGS had the best product price and best freight pricing over three other online companies. I will say this product works great as an alternative to my cast number the only thing that needs a modification is you will need a 3/4" plug to be placed underneath the thermostat housing.
