NEW made in the USA option!
I encourage you to get an aluminum radiator for your Sprite. It's one of the best upgrades you can make, for both your car and for your peace of mind. If you've ever been out on a hot day and been distracted by a rising temp gauge, you'll appreciate the fact that a new radiator will obliterate that worry once and for all.
Original Bugeye radiators are getting pretty old these days and their cooling efficiency is generally somewhat diminished. Even after a good flushing, the capillary tubes are usually coated with deposits and they don't cool like they did when they were new.
Air in Sprite cooling systems (unlike sealed modern designs) contributes to corrosion and reduced efficiency. Aluminum radiators just work better. They offer superior heat transfer. They are particularly useful if you've upgraded to a bigger engine, as more HP=more heat. We have sent more than 330 Sprites out into the world and many have been fitted with an aluminum radiator. It has been really nice to take cooling off the table as an issue for those customers - there is no such thing as too much cooling on a classic British car. You'll notice we are not huge fans of electric cooling fans. We've found these to be wonderful for slow-speed parades or in traffic, but in most cases they seem to block airflow at speed and REDUCE radiator efficiency. We feel that the best line of defense it the best radiator with an upgraded engine-driven fan.
This is our premium aluminum radiator, made in the USA. Some of our customers have asked for a US-made product and we've sourced a great one, a very high quality product. This one will not use your existing Sprite radiator cap (a new cap IS included) and operate at stock pressure depending on which cap you fit.
We also offer two additional radiator options (click links below):
NOTE 1: Your Sprite operating temp should run at about 180 degrees (or less). It may climb to 200 in traffic, sometimes a little more. Temp gauges are sometimes inaccurate, best to check with a handheld IR thermometer to confirm accuracy.
NOTE 2: We use regular 1/2 inch heater hose for our bypass hoses as this material is much stronger and more durable than the accordion bypass hose that is commonly fit. If you have trouble getting such hose to fit, the accordion type we sell is easier to install and also a good choice.
NOTE 3: There is a hole in the side of the radiator for the temp sensor, if your sensor has been relocated you will need a plug which you will find here.
NOTE 4: This radiator takes M6 x 1.0 x 25 mm to install them. The stock sizing is 1/4-28 threads.
