HELP....120 Ford Lehman heat exchanger

Hey all,

I just purchased a new heat exchanger. It is a straight replacement or so everyone says HOWEVER, as you can see from the photos there are no holes to bolt it to my block. Ideas please? I can't just sit it there....or can I?

Mine are fastened with steel straps that are independent of heat exchanger. Lay/glue rubber on strapping for grip and drill holes on strapping to match existing bolt holes. Use new unit as pattern to bend straps nice and tight. Paint red to match.

I'm not near vessel so can't send picture.

Yes, just align holes on each end so that strapping is nice and tight when you close it around unit.

Shane, my heat exchanger was replaced some years ago here in Qld near the Gold Coast. Not sure how the parts were obtained, but I think via the fellow in Sydney who gets them in from American Diesel. I'll be down at the boat on the weekend, so I'll look and take pics of how mine was put back on. Must say I didn't take particular note at the time. However Sunchaser's suggestion would be your best bet, and probably how mine was done also. The hose connections themselves are quite supportive anyway, as long as the hoses themselves are not all old and soft, and it is merely those & the oil pipes that hold the smaller engine oil and tranny oil coolers are installed I think.

Perfect. I look forward to the pics. I think I'll have to go with that. Thank you both.

I reinforced mine with large hose clamps. The bracket broke off, I had it re brazed, then added the clamps as insurance.
I believe clamps alone would suffice.

The parts to install the generic HE should all be available from American Diesel.

I`m sure American Diesel or whoever supplied the new HX will know the mounting brackets, but wouldn`t it be quicker and easier to get some made locally.They are just metal straps.
The FL 135 is the "Super" version, 15 more hp. A different injector pump needed less frequent oil changes.

I saw that, so am I(see signature). We made up similar brackets years ago for an extra fuel tank on a rally car. The bolting together of the two clamp part faces gets the HX mounted tight and firm.

In the plumbing industry here in the U.S., there is a product called plumber strap. It's just a metal strap approx. 1" wide with a hole punched every inch or so. It comes in a small roll and is used to hang pipes . It can be found at most hardware stores and home centers. It is made out of a galvanized metal so would be some what rust resistant. You could also buy some thin flat metal stock, cut to length, and drill your own holes . Also available at home centers.

I have just purchased a 2c218 for my ford lehman 120. It comes complete with mounting bracket. Tomorrow I will check if i need the bracket or if i will need to use the new one supplied. If i end up with a spare you can have it for the cost of postage from Perth.
PM me and i will let you know over the weekend
Cheers Phil

Hi Hallp,
Did you purchase your heat exchanger locally in Australia or source from America?
