Great advice to make sure hoses are in good shape!. Prior to getting our 2021 Yukon we towed with a 2004 Cadillac SRX (NorthStar) V8 with 327HP. Power wise it was great but we had hose issues.
There's a small (3/8"?) hose from the radiator cap -> engine -> fluid reservoir. There's a plastic T that branches from radiator cap to the engine and fluid reservoir. While towing up a mountain it cracked and spewed steam everywhere! and cost a $400 tow bill. A very simple part to make sure it's up to date! We replaced it with new hose and brass T instead of plastic T because it was clear we were stressing the system.
At 18yrs old, we put in a new (refurbished) radiator and hoses and brass (instead of plastic) T and from then on it held up very well (no more break downs) except for overheating going up steep mountain passes. Using the heater as the rig begins to overheat let us operate up to 75-80F but that's not a good solution - very hot on our legs and stressful to monitor the temp gauge all the time.
Thus we transitioned to 2021 Yukon and couldn't be happier but still - it illustrates that an up to date cooling system can more safely let you get full performance out of you're rig.
