They have the bleeder valve built into one of the heater hose lines in that area I believe. Glad you mentioned this because I've had air blocks in the 3.0 Grandams before. They didn't have a way to bleed the system short of 4000 RPMs to burst most bubbles. But it wrecked a nice new set of heads in the shop that were just put on. So keep that in mind if you let out any coolant. ----- Original Message ----- From: Rhonda & Steve To: blindhandyman@yahoogroups.com Sent: Tuesday, February 19, 2008 1:26 PM Subject: Re: [BlindHandyMan] Oldsmobile thermostat
keep in mind you will need to bleed the system after refilling the coolant this is very important if you have air trap in the cooling system you will have problems like know heat and over heating it could get ugly in a hurry ----- Original Message ----- From: Ron Yearns To: blindhandyman@yahoogroups.com Sent: Monday, February 18, 2008 9:22 PM Subject: [BlindHandyMan] Oldsmobile thermostat Well gentle handypersons, it appears I have around the thermostat housing and it also acts as if the stat is stuck open. This is on a 2002 Olds van with a 3.4 engine mounted cross wise with frontwheel drive. The book calls for removal of the crossover pipe before removing the thermostat housing. Has anyone had similar experience? Is the crossover pipe removal absolutely needed? I am fearful of breaking exhaust bolts, studs. Comments and experiences requested.
