Coolant fill & Fan Issue
Hey all, I’m new to the forum but happy to be apart of it. I recently did water pump & thermostat replacement on my 99. I went through the bleed procedure a bunch of times with the rear in the air. Now I’m noticing with my durametric that my temps are getting pretty hot but no sign of the fans kicking in at temp. My temp has gotten up to 96 degrees C. I’ve tested fans by running Ac as well as test with durametric, just replaced my coolant cap with the updated 04 as mine was 00 but still nothing. Btw also checked relays and two fuses, just scratching my head at this point. Hope someone can help me out. Thanks

You have an air pocket.

Yup. Air pocket.
When I replaced my WP and therm in addition to raising the rear I left open the coolant tank bleeder valve open for a couple of driving days. Worked for me. Also, just after completing the procedure I drove up a steep incline hill. :cheers: |

For starters, I'm no mechanic. That said, I read a lot and have done a number of repairs on the Box I have owned for ~14 years now, much of the info derived from this forum.
When it comes to refilling coolant, seems to me that using a vacuum filling system is far away the best approach. That said, if you want to go the other route, read insite's recommendation in this thread. (He's a member who, unfortunately, doesn't frequent this site much at all anymore. I say "unfortunately" because it seemed to me he did a lot of his own work and had a pretty good idea what he was talking about in his comments/recommendations.) http://986forum.com/forums/boxster-general-discussions/28548-cooling-system-woes.html |
Uview Airlift 550000. I have had one for several years and used it multiple times without issue. It works just as easy as the attached video demonstrates. One and done. No need to drive around with the bleeder open, etc.

a lot of people over-think this. open the bleeder & reservoir cap. fill it up w/ coolant. start the car & let it warm up. once the thermostat opens, the coolant level will drop. shut the motor & fill it back up with coolant. now go for a 20min drive with the bleeder OPEN. go home, shut the bleeder, park the car, and DO NOT OPEN THE RESERVOIR CAP. let the car cool off on its own. once it's cool, top it off again & you're good.Like I said, if I was doing this without the airlift, this is what I'd probably do. |
I have never used a vacuum bleeder for the coolant and my experience has been hit and miss. Sometimes the manual procedure works fine and other times it doesn't.
When it doesn't, I end up with the temp gauge going to nearly full hot after just a few minutes of driving. I never worry about what the fans are doing because my car doesn't have radiator fans - both have been removed to reduce weight. Then I let it cool down, refill/top up as needed, and rebleed to the best that I can and then drive it again with the cap on but the bleeder valve open. Usually I get it working normally by the 2nd or 3rd try. If I still couldn't get the coolant temp to act normally after 3 trys, I'd drain the system and start all over from scratch. Or buy a power bleeder. :o |
whats wrong with 96C? Thats very normal as far as I'm concerned. Low speed fans dont kick on until 100c as i recall it and highspeeds is like 110C or so.

I'd just do it old-school. The Airlift is a great tool... gadget... but, what? You changing out your coolant every three-months?
|
What FRODO said. I have a 99 have done this three times works flawless. Twice I have replaced water pump once I added an S center radiator. I had a UVIEW sold it personally thought it unnecessary. Open the bleeder on the coolant NOT the cap drove around my neighborhood for 20 minutes close the bleeder. Never had a problem. Just my experience.
