Beretta 3100 engine coolant leak
I have a 1996 Beretta 3100 engine (90,000 miles) that has a substantial coolant leak near the rear of the engine and possibly where the heads meet the block, but I can't be sure.
Did this model have any history of head gasket failures? Are there any pitfalls that I should be looking for in replacing the head gaskets, which is what I am suspecting? Are there any pointers as to the procedure? I would appreciate any comments from those that have had experience with this problem and engine. My email, if you prefer direct contact , is dieterschmied@gmail.com . Thanks |

Re: Beretta 3100 engine coolant leak
I would guess your heater hoses that run into the firewall to the heater core.

Re: Beretta 3100 engine coolant leak
I agree, if it's a substantial leak, then the source should be pinpointed before assuming a head gasket...

Re: Beretta 3100 engine coolant leak
I had already disconnected the heater hoses at the firewall. The leak source is higher.

The intake is above the head gasket area. These are prone to leak also. |

There is a different symptom for each and I could possibly repair the obvious engine defect and and overlook a potential defect that could have been addressed while the engine is apart. |

Re: Beretta 3100 engine coolant leak
If you are refering to the 3.1L GM engine having a problem? yes. The lower intake manifolds are notorious for leaking at the coolant jackets because of gasket degradation. There is a seller on ebay who has a aluminum reinforced gasket for sale. They leak. leak leak. Is it your current leak? I dont know, I would have to see the car for myself. Change the coolant out once a year.Usually unless you have flushed the system right when you got the car, the dexcool has eaten up the plastic intake manifold gasket. There has already been a lawsuit about this. Me personally Im going to try the aluminum reinforced gasket.

Re: Beretta 3100 engine coolant leak
As suggested, get a pressure tester, to "pinpoint" the leak, rather than guess....
Big difference between 3.1 and 3.8 engines....... you do not have a 3.8.... |

Re: Beretta 3100 engine coolant leak
Yeah this thread is old.
So did you figure it out? I put my money down on lower intake and or head gasket. Felpro makes a pretty serious gasket set, 100 bucks. Ive put two of them on different vehicles, never had any problems. Update on myself, I no longer use dexcool at all period end of story. Prestone is a dex clone. same stuff. I just bought the walmart junk 8 dollars a gal. Why? It had two less ingredients than dexcool. not sure if those two ingredients help or hurt . The key with these engines, is to not let air get into the coolant system, and dont let the coolant get old. Keep it fresh and your good. Toyota also uses dexcool FYI. |
