Radiator on my Gt40
- Thread starter Vinny P
- Start date
I purchased the 3-row radiator. The quality looks good. I started the install. This is just a mock-up, I have many more photos of the nearly completed install but I am having a problem uploading

It worked out well mounting the radiator. I have not added coolant. I will let you know how it turns out once I do. I replaced the AC hose going to the dryer with a hardline. I may reroute it below the suction line before I charge the system. I fabricated a bracket on the right side and had to drill new holes on the left side of the car, pretty straightforward. The extra tabs that were welded on the upper and lower sections of the radiator worked out well for mounting the condenser, and also if you want to hard-mount your fans.

Vinny, have you been able to verify that the radiator is truly a multi-pass or at least that lower input is internally going to the top such that it is a cross flow? Cheers, Randy

Does anyone have the original dimensions of the radiator? I need the original documentation. I want the radiator to look exactly like the original and, if possible, improve its performance.

This is what I found online.
The exact factory‑issued 1966 GT40 radiator drawings are not publicly released, but the closest verified data comes from Serck (the original supplier) and period‑correct Mk I/Mk II measurements shared by restorers. The best‑documented “original‑spec” dimensions match the Serck copper/brass units used on Mk I cars.
Dokładne, fabryczne rysunki chłodnicy do GT40 z 1966 roku nie zostały publicznie udostępnione, jednak najbliższe potwierdzone dane pochodzą od firmy Serck (oryginalnego dostawcy) oraz z pomiarów modeli Mk I/Mk II wykonanych przez restauratorów. Najlepiej udokumentowane wymiary „oryginalnej specyfikacji” odpowiadają miedziano‑mosiężnym chłodnicom Serck stosowanym w modelach Mk I.
Closest Verified “Original‑Spec” Dimensions
These measurements come from restorers referencing original‑type Serck radiators (Mk I), which are the closest surviving match to 1966 GT40 units:Radiator Core (Mk I / early Mk II)
- Core width: ~24.4 in (620 mm)
- Core height: ~12 in (305 mm)
- Core thickness: ~2.0 in (50 mm)
- Rows: 2‑row copper/brass
- Inlet/Outlet: 35 mm (1.4 in) each
Overall Dimensions
- Overall width: ~29 in (730 mm)
- Overall height: ~12.6 in (320 mm)
- Overall thickness: ~2.2 in (55 mm)

Thanks for the information. I'll get to work and try to recreate it according to these dimensions.This is what I found online.

These numbers match the closest reproduction of the original Serck radiator, which is why restorers use them as the benchmark.

Thank you for the photos
I noticed in the photo that there's a partition divided into two. I'll make the same one and the second one divided into four and see which solution will have better performance.

SERCK Performance Copper & Brass Radiator for Ford GT40

Are you looking for Mk1 or Mk2 radiator dimensions, they do look different. 1011 is a Mk2.
I need one for my GT/1011, MK2, but I'd love to compare the differences, and if I do, I'd do both types for the MK1 and MK2. Do you have any information on the differences? Maybe some dimensions or other information?
This is what I found:
Notes on Authenticity
- Mk I and Mk II radiators were extremely similar, both built by Serck in copper/brass.
- The Mk II (427 cars) sometimes used slightly thicker cores for endurance, but the external dimensions remained nearly identical.
- No official Ford blueprint has ever been released publicly; restorers rely on surviving originals.
- I looked it up on Copilot, AI that can find reverse-engineered drawings of the originals.
