1997 GMC Suburban 2500 Question: running temperature
I would like to know what the normal running temperature is for this engine because I just bought this suburban from a unscrupulous private owner anyhow, it runs at 220 degrees and I'm sure this is too hot. There is no visible leak for the water just I'm thinking this is either a head gaskit or cracked head but there's no oil in the radiator and no water in the oil???? can anyone help me? - ggmart71
This vehicle generally runs between 190 and 200 degrees. The problem could be a cooling system that is not working properly or a thermostat that is no longer working in the proper range. It could also be as simple as a gauge that is not reading right. If you have any more questions feel free to check our web site www.leoandson.com - leoandson
