What kind of coolant does a cat C7 engine use?
Cat C7 Engine: ELC Coolant or Something Else? I am the proud second owner of a 2007 Fleetwood Providence with a CAT C7 engine. The original owner does not recall if he had ELC coolant installed. The coolant is red in color. I’m lead to believe ELC is red and the ‘regular’ coolant is something else.
When did Caterpillar C7 engine go into effect?
The stricter Tier 4 emissions requirements went into effect January 1, 2004. The Caterpillar C7 was released in 2003, only months ahead of the Tier 4 ratings change, and replaced the popular 3126 model. Older CAT engines like the 3116 or 3126 were essentially grandfathered into the older tier rating requirements and did not need to be upgraded.
What kind of fuel does a cat C7 ACERT use?
In 2007 diesel fuel itself changed to Ultra Low Sulfur Diesel or ULSD. The fuel change dictated that the fuel system of the CAT C7 ACERT needed to change to a common-rail injection system. The new common-rail injectors took injection pressures to 25,000-27,500 psi. The fuel transfer pump supplies the fuel to the fuel rail at 280 psi.
What kind of valve actuation does cat C7 use?
Within the design of the C7, the turbos use variable geometry valve actuation controlled by the ECM to adjust the perfect amount of airflow into the combustion chamber. This variable valve actuation also allows for the CAT C7 to offer an integral jake brake on two of the heavy duty diesel horsepower models.
Do you need coolant for a Caterpillar engine?
If not, with the low price of coolant compared with engine or radiator, it may be wise to drain and replace with a coolant you will know– and yes many of us with Caterpillar engines have switched to ELC (me included). Also, suggest you join the Caterpillar RV Engine Owners Club, an FMCA Chapter.
Is it bad to mix coolant in an engine?
You are wise to ask, as mixing coolant chemistry is not a good idea in any engine. Sadly, color is not a good indicator. It is within a particular coolant manufacturer, but not across the industry. If the OE can recall where he had it changed, call them and have them pull the ticket.
Are there any problems with the C-15 cat?
C-15 Cat Engine Problems. Discussion in ‘ Trucks [ Eighteen Wheelers ] ‘ started by dave_0755, Nov 4, 2010 . I’m hoping someone with knowledge of the C-15 can help.
How much power does a C-15 cat engine have?
No disrespect but chances are this guy does not own an Acert! They are made to be lugged, all the way down to 1100 rpm. It’s not the same as an “E” or the first C15’s (6nz) there is absolutely no power above 1500 and running one there will do nothing but burn fuel.
