Installed a new Wizard Cooling Performance Radiators https://wizardcooling.com/ in my Austin Healey 100. The build quality is great and would recommend this radiator over a no-name Chinese radiator. I had a few questions, and the company gave great support. They make aluminum radiators for all sorts of cars and I would use them again.

That looks lovely and I am a little envious but I was thinking of re-using my rad exactly as it is assuming it doesn't leak that is. Do new rads make much difference?

The Wizard radiator has better heat transfer. There was nothing "wrong" with my original radiator, but when I was in stop and go-traffic (I live near Mt. Vernon, VA near George Washington's home and when the tourist are there there's a lot of stop and go traffic), the car would over-heat as the temperature got over 190 degrees.

While I had the old radiator out, I installed a 12" Spal fan in front of the radiator. Clearance is so tight, I had to cut a slot for the frame weld to rest to allow the fan to sit a little lower. I also didn't want to drill any holes. So I used aluminum angle "iron" with 1/4" x 3" long stainless bolts with stainless tubes (as spacers) to hold the fan against the double crossmember.

I also added a 5 bladed fan I got from Healey Surgeons and made a deflector on the (right) non-carb side (figured the steering column and cold air duct on the other side didn't make it worth it on the right side.

I also have a louvered bonnet to let out more heat.

So with luck I won't be stuck beside the road this Summer!

I've found the biggest cause of overheating to be sediment build up in the Engine Block and Cyl. Head Water passages.

Each time I rebuild an engine I remove all the core plugs and clean, scrape, poke out all the passages.
The amount of ' Crud ' which can be removed is amazing.
I managed to fill a Pint Tumbler with the dry rust and sediment from a 100 Block. The head was extra.
I've even found old Core Plugs which have been pushed in rather than properly removed.
Add to that nuts and bolts and bits of casting wires.
If you can find a workshop which will do an Acid ( ? ) bath clean. Do it .

Similarly , the Radiator can become Gunged up
Flushing with a water hose will remove a lot of sediment.

With a 5 blade Fan fitted I've never had any trouble with overheating.
Even in traffic in our brief summer in Scotland.

Thanks for those comments. I am trying to do this rebuild on a school teachers budget so I have to consider every bit of expenditure carefully. The chap I bought the box of bits (i.e. my car) off had rebuilt the engine but not fitted the core plugs which is a job nearing the top of the list of things to do; I'll have a little fish about before I fit them.

Cheers

I bought the Spal fan on EBay because I didn't want to pay full price for a fan and was willing to search and shop around to get the best price ($55 with free shipping). I also have a MGA and BT7, both in need of restoration. My plan is to buy all the parts below retail by shopping on-line as much as possible...

If you can, fit BRASS core plugs.
The steel plugs available in the UK are rubbish and corrode through in no time.
