Product Description

Howe Radiators has been well known as a manufacturer of performance radiators, and we have joined teams with them to produce a radiator specifically for the Z32. For over 17 years this radiator has been the go-to for cooling performance for the 300ZX TT.

It features lower mounting studs for use with the stock radiator mount insulators, a thick core of 2.25", and over-sized end tanks to provide greater coolant capacity. Of the best features, this radiator uses a billet aluminum and a CNC machined neck; no more problems with leakage from stamped aluminum necks used on some units. Also, this radiator uses a metal bleeder plug unlike the plastic plugs that almost always leak found on some of the other brands.

This radiator is fitted with the necessary fan shroud mounting holes and is a direct bolt-on replacement to the stock radiator.

We keep a large stock of these radiators ready for quick shipment.

Although not essential, we recommend these Radiator Brackets hold it firmly in place, or optional upper radiator mount brackets can be added to your order in the drop box below.

Add a discounted Z1 Silicone Radiator Hose Set to your order with your Z1/Howe radiator, and the hoses ship for free!

 Automatic Transmission owners PLEASE NOTE:
This high performance, aftermarket radiator DOES NOT include an integrated, internal transmission cooler. Customers installing this radiator into an automatic transmission equipped vehicle must add an external transmission cooler. Z1 Motorsports stocks and sells a variety of both universal and vehicle specific transmission coolers which can be found HERE.

Overall the fit works, however you do need to modify the OEM fan shroud otherwise the OEM fan will hit the shroud on the drivers side near the middle of the shroud. I dremeled out a section. The bigger issue I'm having is radiator caps are getting stuck in the neck, I've tried two different brand new caps, and they both get stuck inside the filler neck. Seems the circumference is too small. Hoping the cap issue still allows the cap to relief pressure. If I had to do it over again, I would just get an OEM rad.

Great Product, This was purchased after having major trouble with 2 other radiators of a different brand that uses Aluminum Bolts instead of Brass Fittings. Perfect fitment for your 300.

I purchased this radiator and do to the customer service(ray), I decide to go ahead and purchase a Mishimoto radiator.( just to compare appearance). I am sure the z1 radiator will perform great, but I was extremely disappoint about the finish look of it. it appears to be stored to the elements.( so your new radiator looks like its 9 months old or has 1000 miles already on it) Also, on top their are sharp edges that weren't filed down. and packaging was HORRIBLE..( but that seems to be average) over all this product dose not have a appearance currently. now as for the mishimoto... they have great packaging, awesome welds, finish, radiator cap, and there marking on there product.

Fitment was NOT perfect but close to it. Only required a small bit of trimming on the upper coolant hose.

Amazing. THE BEST radiator available for the Z32 by far, and thats not an opinion. The fit is flawless, everything works like it should, it's very solid and strong with great welds, and I haven't even had to turn on my radiator fan since I put it in about a week ago. It holds a lot or antifreeze (I had to put about 2.75 gal in) which is great, but expensive when you refill it.
