Just tossing a line out in hopes someone can advise. Ive got a G1900 that came to me with a complaint it was running hot and the alarm was going off.

Found it was 2 quarts low on coolant, and once I topped it off, I started it up to check it out. It was hard to start, puffing both black and white smoke, but once it cranked and warmed up, ran really smooth.

But it definitely is leaking coolant from somewhere around the radiator on the right side. Not the overflow hose. Possibly the lower main hose to the radiator, but seems like it very well could be the radiator itself. I couldnt see where it was coming out exactly. The mower is, I suppose 30 years old with 1,700 hours. A couple questions. 1. How hard is the radiator to remove. (And how much are they? Any good aftermarket options?)2. Has someone reading been through this before and what did you find? 3. Any other advice would be appreciated. Thanks
