Well, after replacing my old leaky stock radiator in my 87 turbo to a Fluidyne radiator my coolant temps have rased. About 10 degrees and up hills and just sitting and idling it heats up quicker. I have maid sure to get all the air out of the system still higher temps. Anyone have any ideas what's going on?

 

Absolutely no clue. Mine has made my car run incredibly cooler. Maybe you just happened to get another problem with the coolant system now

 

Do you still have the clutch fan, or switched to an e-fan?

 

Yeah what fan you running? and you might check the thermostat. That radiator has been proven time and again to lower temps. What is in front of the rad?

 

First thing I'd do is check the thermostat, then make sure nothing is blocking the radiator, make sure the coolant is topped off, and go from there. Most importantly do you still have the fan shroud on if you have a clutch fan, if NOT then you have put a huge damper on your cars ability to cool. Put that back on , good luck.

 

Is this a common occurence with cars that have the radiators switched to an upgraded aluminum unit along with a fan kit? I know that I have read about other people having this problem before. Just wondering because I have a Fluidyne and a FAL kit waiting to go on my car.

 

No this isn't common. My gauge reads remarkably lower than it did before. More than likely, there happened to be a problem pop up elsewhere in the coolant system somewhere like I said before.

 

Yeah, I'm running a fluidyne with stock fan and shroud, 50/50 water coolant mix and a bottle of water wetter for good measure, with a 180 degree thermostat, that thing NEVER gets hot anymore. Hell in the winter I can't use the heater or it never even gets to 170 degrees hahaah.

 

Yep, only problem I have is it takes forever to get the car warmed up

 

What is a good electric fan to use?

 

Not to steal this thread, but need an answer as to how can a larger radiator not allow the engine to come up to temp...As long as you are running a thermostat. I put a huge radiator in my Jeep and the temp gauge will move up and down as the thermostat opens and closes, but it will always come up to temp.
Just curious....

 

If the thermo doesn't close properly it can do it. Also it will take longer because the larger rad holds more water. In the winter, the cold air on the hearing coils (which are just a small radiator in the passenger compartment) is enough to hold engine temp in check...

 

Just thought I would ask because I had read this somewhere else. I was mainly referring to the removal of the fan shroud because I believe that they were saying that because they had removed it the car wasn't cooling properly. Something to do with the fact that the car was designed to have it there, but this would be with the stock friction fan though.
