Electric fan swap (nor cal)

[E30nub1]

Soo with me moving soon back to the east coast for a few years I have been doing a few things to my car. And I am about to try and tackle the last MAJOR issue I have had with the car. cooling system. Aka (PITA)

so since I first have gotten the car thermostat/housing , WP, fan clutch, have all been replaced. And I still get the 3/4 line every time im in traffic for more than 5 min. And as I said with me moving to a significantly warmer climate than norcal I want to get this fixed b4 I head out. So from what I have been reading even if the fan clutch is replaced that may not solve the problem.

So I am thinking of just replacing the rad. Resivor/ cap and putting in a electric fan. Radiator and Resivor are the easy things and wouldn't take me more than a hr or 2 but the fan is what I am worried about. Considering I have no wiring exp what-so-ever it's one of thoes things I am not sure that I want to attempt because one mess up..... And well it would not be good. Suggestions? Comments?

First did are you sure you bled out the air bubbles?
second, pop the cap on the reservoir, if it is under pressure the cap is good.
third check the flow on the radiator, most likely its 1/2 clogged and thats why you are over heating.

Also is your aux fan working?

While a working aux fan might keep the temp down, it doesn't address the cause of the high engine temperature at idle. That will be air in the cooling system, a bad fan clutch, or a clogged radiator. Since the fan clutch has been replaced, a failure to properly bleed the cooling system, a head gasket leak, or a bad radiator are the likely causes.

Haha. I meant to say fan clutch, but then I reread the original post and it was listed. Sorry.

There is a possibility that the gauge sender is dodgy.
You could remove the water temp gauge sender, sand the probe, and reinsert to see if the reading changes.
Or you could try a new one.
The radiator has plastic composite end tanks which get brittle, so installing a new radiator could be considered to be a necessary maintenance item in this case.

At the end of the day though, the habitual rise in coolant temps is ominous with regard to head gasket health.
