hi
Usually 50 / 50 , up to 60 % antifreeze in colder climates
Open the 1994 Regal petcock and drain the old coolant into a pan. The coolant is toxic to animals so dispose of properly. Close the petcock when the fluid stops draining. Fill the coolant through the radiator cap opening, using the proper type of antifreeze.
Regular green antifreeze of any manufacturer will be fine in a 50-50 mix with water
Coolant Recovery Reservoir. There is no sensor in the coolant recovery tank on a 1998 Buick Regal.
On a 1993 buick regal it is on the side of the radiator.
total coolant capacity of 3.8L buick regal custom? doing a radiator flush so i need to know how much coolant to buy
On a 1993 buick regal it is on the passager side of the radiator. Hope this helps
It is located in the bottom of coolant bottle.
possible leak in heater core.
Either the coolant reservoir is low on coolant or the coolant level sensor is NG.
Low coolant? Thermostat not opening? Water pump not circulating coolant?
Yes, as long as you are certain that it is the coolant reservoir.
