Coolant Replacement — Fresh Loop, Cool PC

Old coolant loses corrosion inhibitors, absorbs plasticizers from tubing, and grows bio-film. MSFREEZ drains your loop, flushes it with distilled water, and refills with your choice of premium coolant — then leak-tests for 24 hours.

What you get

Full drain of old coolant
Double distilled flush cycle
Premium coolant refill (EK, Mayhems, Aqua Computer)
New biocide dose
24-hour leak test after refill

Coolant options we stock

EK CryoFuel (clear, solid colors, translucent). Mayhems Pastel (opaque, wide color range). Mayhems X1 (clear performance coolant). Aquacomputer Double Protect Ultra. Distilled water + Mayhems Biocide + Corrosion Inhibitor for the purists.

When to replace

Standard schedule: every 12 months for premix, every 6–9 months for distilled + biocide loops. Immediately if coolant is cloudy, discolored, contains particles, or if the loop has run hotter than baseline for a week.

FAQ

Can I bring my own coolant?
Yes — bring sealed factory bottles. Labor stays EGP 1,500; we deduct the cost of coolant from the invoice.

Which coolant lasts longest?
Distilled + biocide can outlast premix if kept clean, but premix (EK/Mayhems) has better corrosion protection out of the box.
