This is what we feel is the best radiator for the V8 Z (see picture below). It also works very well on the six-cylinder Z car, and it weighs about 9 lbs less than the stock 6-cylinder radiator.
We no longer sell radiators with the automatic transmission cooler in the passenger"s side tank
This radiator is made for Stealth Conversions. It is the base radiator for 1984-1986 V8 Camaro’s, but with a thicker core (1-3/8" thick, compared to 7/8" for a stock radiator). It is light, inexpensive, and does an excellent job of cooling. It has the correct overall dimensions to fit in a Z car. The heavy-duty radiator for a 1984-1986 Camaro has a 1-3/8" thick core, but it has an overall width of about 30" (compared to 25.25" on the radiator shown above) which is too wide to fit between the frame rails in the Z car.
We recommend our complete Stealth Conversions radiator package (DAT-500), which includes our Radiator Mounting Bracket Kit (DAT-125), Radiator Hose Splicers and Reducers (DAT-501), and Hose Kit (DAT-502), together with the Radiator (DAT-121).
All of the items in the DAT-500 package can also be purchased separately.
The radiator shown below weighs less than 10 lbs pounds (empty). The side tanks do not hold a lot of coolant, and this also saves weight. When the radiator is filled with coolant, it weighs 15 lbs. The brackets which hold the radiator weigh 4 lbs, for a total weight of 19 lbs.
By comparison, a stock 280Z radiator weighs 20 lbs (empty), and 30 lbs full of coolant.
Please note, we no longer sell radiators with the automatic transmission cooler in the passenger"s side tank
