"transmission fluid leaking from fitting below radiator cap after replacing radiator on 99 surburban
It sure is. Leaking radiator fluid only causes the coolant system to de-pressurize and not effectively cooling all the internal working engine parts. As to repair costs, one needs to evaluate the cost of repairs vs replacing the radiator. If the car is older, then replacing the radiator might be the way to go.
possibly the radiator cap is not holding pressure, try replacing it
Shouldn't be more than 20 bucks
The cost varies widely depending on the make and year of the vehicle.
The radiator will need to be replaced. Sometimes, it may seem that the radiator itself is leaking but it could be the radiator "hose" that is leaking. In this case, the radiator hose needs to be replaced and clamped tightly.
Check radiator hose, leaking water pump, look for hole in radiator, leaking coolant bottle or leaking seals.
I had a similar problem and ended up replacing both the lines and the radiator.
A leak in a coolant system can usually be fixed by replacing a hose. If the leak is at the end of the hose, a new clamp might be necessary. If the radiator is leaking, the radiator might need to be replaced.
Maybe it's not the radiator. Maybe it is one of the radiator hoses that is leaking. Or possibly the radiator cap or a level sensor.
sounds like pressure relief valve if replacing the valve doesn't stop the leaking you may have to much pressure in your cooling system mainly a Head Gasket leak.
Leaking radiator? Leaking or loose radiator hose?
