How often you add coolant?
Is it normal to add coolant and how often/up to what amount?
|
I have been adding just whatever amount it takes to go from the low mark to high mark on the reservoir float once or twice a year recently with no visible signs of any leaks,(suspect the coolant pipe and in the valley pan it evaporates I suppose), as it is just a small amount. |
A few mL a couple times a year is OK. 100mL a few times a month is not OK. Look for dried residue to pinpoint leaks.
|
This summer checked and added to bring it to high mark, now 4 months after I added 1 quart of coolant to bring to high mark again.
Was not sure if this is normal? |
That sounds like a lot. Does your 'low coolant' warning come on?

Use a UV light to look for coolant leaks. Coolant shows up like radioactive slime under UV light.
Harbor Freight has a UV flashlight for about $7 and it works great. That is how I found a leaking fitting that was basically ready to fall apart. I have the N62 V8 and it was the Y connector for the upper head return lines. The fitting was make from something like Bakelite and was falling apart. I replaced it with a brass T. |
No coolant warning message, just checked and added 1 quart after 4 months.
Around 1300 miles between additions. Will get UV light-thanks for the tip, checked with phone light noticed small coolant amount on top front of the engine, see the 1st attached picture showing the direction/location. Pictures 2, 3 and 4 are taken from website source with exposed area, arrows pointing where little coolant was noticed. This could be damaged hose, cracked Y connector or loose clamp, will have to check closer after removing top engine covers. Is removing the intake manifold a must in this situation? How complicated it is to get access to this area? https://i.postimg.cc/tC8tQqx2/cool1.png https://i.postimg.cc/QM5DsGqp/cool2.png https://i.postimg.cc/qqBH8tHL/cool3.png https://i.postimg.cc/vHBdT6z8/cool4.png |
i never add coolant. I just replace it every 4 years.
|
Ordered a complete hose with 2 clamps, based on pictures it should not be too complicated to replace it.
About UV flashlight, is this detecting coolant without having to add any dye or having to use glasses? |
