Water wetter or OEM
Im changing out the OEM top mount intercooler soon and was wondering which was more optimal to refill with... Water wetter with distilled water or OEM coolant?

OEM coolant to prevent rust and provide protection and lubrication for the cooling loop, any other coolant would be risky or incompatible so I always recommend the oem coolant. Also the OEM coolant is a concentrate so you will have to dilute it with distilled water anyways.

Holy Flashback Batman. Water wetter is what we/I used in the e36m3 that saw high heat because of the necessary fan delete mod (another story). I don’t want to make this lengthy, but even with the proper dilution, your t-stat reading will potentially be tricked into staying cold most of the time especially during highway driving and could cause all kinds of false readings. This was ok for an Obd1 s50 motor. The S55 is so far advanced with tech and cooling that it’s almost absolutely not worth the risk imho.

Lots of uninformed responses here. Been using a bottle of water wetter in my cooling system for my E46 M3 for over a decade with no corrosion or issues. It definitely helps with the added power and keeps the coolant from film boiling/nucleate boiling in the cylinder head while transferring all the extra heat. I've recently replaced my M2C top mount intercooler and added a bottle to both my intercooler cooling system and engine cooling system. There is no issue with the factory cooling system and hitting temperature targets of the thermostats. When used with oe coolant and distilled water I can verify that there will be no issue.
When used in any other manner like a pure distilled water solution with only water wetter as an additive I cannot comment.

Ive run Evans Coolant in all my previous track cars.
https://www.evanscoolant.com/ I'll wait until my warranty is up then add it. There is no water in it and its a one time fill. Jay Leno uses it in all his cars. Water is still a better conductor of heat removal but if it reaches 212 degrees then all kinds of problems arise. One f the best things about EVANS is it doesn't expand or boil like water does. YMMV HAZMAT

Curious, why are you adding ww to your M2C’s coolant? Are you overheating? Track? Last edited by clutchdj; 05-31-2020 at 08:34 PM.. |

See below for the purpose as in this link: https://www.redlineoil.com/waterwetter WATERWETTER® Unique agent for cooling systems that doubles the wetting ability of water Rust and corrosion protection allows for use of straight water in racing or reduced antifreeze levels in warm climates Improves heat transfer and reduces cylinder head temperature Use one bottle for most passenger cars and light trucks, treats 3 to 5 gallons or 13.2 to 15.9 liters, vehicles with larger cooling systems should use two bottles, small cooling systems should use 1oz (3 to 4 capfuls) per quart Compatible with new or used antifreeze (including DEX-COOL® and long-life versions) to improve the heat transfer of ethylene and propylene glycol systems Satisfies ASTM D2570 and ASTM D1384 corrosion tests for glycol-based antifreezes Contains no ethylene glycol

Is anyone having any heating issues to justify taking additional precautions? Seems like the stock system is fine even with tuned S55's. Mine's tuned and i've not had a single issue at the track or otherwise. Can't say exactly if any timing has been pulled but i doubt it.
