I have had three radiators put in by my mechanic spring massive leaks within a year or 2 of installation. Can anyone recommend a reliable brand I can get to stop this madness? I have a Stewart hi-flow water pump installed. Looking for a 4-row.for automatic and AC. Thank you!

Dewitt is what I put in mine, but it ain't cheap.

Mr D.

My first question would be where is he getting these radiators? Even a crappy repaired copper radiator should last over 2 years. Maybe find a new mechanic????

The 1977 had an early design (curved upper neck) and a late radiator (straight) neck. Check your car before ordering anything. Below is the late version. If you have the early design, order a 76 radiator.


Check this one out

Get a new mechanic along with a new rad.

I bought one from AutoZone 12 years ago and installed it in my 77. It's never leaked and never overheated. I probably just happened to get a good one.

But, I'm going on 14 yrs with the unit in my 75, never looked back. Worth every penny.

Wonder if you have some cyl pressure working its way into your cooling system, you shouldnt have that issue
Did it do this prior to your waterpump change?

I had the pump done way back and the radiator at that time lasted a long time. The failures are more recent replacements.

Thank you for the replies and suggestions. I will probably go with a DeWitt. I've had this car for 20 years and the radiator is the weakest link over the past 6 years (AC compressor also seems to fail more than it should, but that's a minor problem)..
