Disposal of Used TPIM Coolant
Used ethylene glycol based TPIM coolant (antifreeze) is a
regulated substance requiring proper disposal. Check
with your local authorities to determine the disposal
rules for your community. To prevent ingestion by ani-
mals or children, do not store ethylene glycol based TPIM
coolant (antifreeze) in open containers or allow it to
remain in puddles on the ground. If ingested by a child,
contact a physician immediately. Clean up any ground
spills immediately.
TPIM Coolant Level
The TPIM coolant bottle provides a quick visual method
for determining that the coolant (antifreeze) level is
adequate. With the engine cold, the level of the coolant
(antifreeze) in the coolant recovery bottle should be
between the ranges indicated on the bottle.
When additional coolant (antifreeze) is needed to main-
tain the proper level, it should be added to the coolant
bottle. Do not overfill.
Points to Remember
If an examination of your engine compartment shows no
evidence of TPIM cooler or hose leaks, the vehicle may be
safely driven.
•
Do not overfill the coolant recovery bottle.
•
Check coolant (antifreeze) freeze point in the coolant
recovery bottle. If coolant (antifreeze) needs to be
added, contents of coolant recovery bottle must also be
protected against freezing.
•
If frequent coolant (antifreeze) additions are required,
or if the level in the coolant recovery bottle does not
drop when the engine cools, the cooling system should
be pressure tested for leaks.
