Yesterday I changed my coolant I mixed about 65/35 Water...
What I noticed now that when I turn the heat to 23C it is no where close where it use to be now I have to put at like 29C to get the same heat I use to get at 23C.

My Question is, because I used more Antifreeze could it be there is less water than before and water carried heat better than antifreeze?

***Also my engine temperature is normal just a one line under half way.

Any help would be great...

Thanks

 

You probably still have air in the system. Get that out and you should be good.

 

A bleed the system like a dozen of times...

- I opened up the relief plug (several times) pressurized air came out a few times.

- Ran at 1500-2000RPM for about 15 min and rad cap off (some bubbles came out) and the cars front end was jacked up about 2 feet in the air.

Today I drove the car, I had 24C AUTO on which seem to work fine, I don't know if it maybe finally mix in properly or just started to work.

 

Glad it's working out for you.

 

Your coolant is too strong. I remember old TSB regarding strong coolant and low heating performance

 

cant you just use the premixed 50/50??

 

It's a real production to get the air out. I've bled my system like 10 times and I still don't think it's bubble-free.

 

next time i do this ima just have the dealer do it lol. i dont wanna worry about bubbles and what not

 

When I had mine replaced it took the dealership about 30 mins to burp the system.

 

I mixed up 75/25 because the 50/50 is only good for -35, last time I went skiing to Quebec it was -43C so I want to be worry free.

Now after adding additional water I'm back to where I was all good with good heating back again. After multiple times bleeding the air and burping the car, its finally back to normal.

Tomorrow Spark Plugs and maybe Throttle body cleaning...
