Driving around today i noticed my thermostat was increasing between half and full, but then after a good floor it would drop back down to half and sit perfectly!! I pulled over and the engine didnt seem over-hot, water wasnt bubbling, however the fans wernt kicking on when they should(when thermo gets half way) they would kick on just above half!! Weird? These fans were not working and got replaced by the auto elec around 2 months ago!

I parked it out on flat and just checked the water levels, and it has used no water. I flushed out the radiator and topped up with coolant just before the new year?

What can this problem be?? One of the relays for the fans?? Or just the fact it was 40 degress in melbourne so the road would be sitting at around 60??

Help, im stuck!!!

Cheers, Liam.

The relays are a very common hassle on these cars, I have seen them go when only a few weeks old. The metal cap on them does not allow them to cool down enough

The best fix is go to a wrecker and get some relays from a first gen pop then in and you should no longer have any issues

I have to ask, how are relays from a (much) older car better then newer relays from say a 95 TS?

The second gen relays use a metal cap, which tends to "trap" heat released by the relay (the metal conducts the heat). It results in a much shorter life span. However the first gen relays use a plastic cap which does not have the same "trapping" effect so the life span is significantly longer. The internals of the relay are otherwise the same.

A design oversight by the manufacturer of the relays that Mitsubishi happened to get caught up in during the second gen production run.

It's knowledge and insight like this that makes the AMC forum, and it's member's, worth their weight in gold!

lol

Explain that utterly useless post?

Exactly. I would have stated to use the third gen ones but they do not fit. The first gen relay are much better built (and backed lol) than the crappy 2nd gen ones.

Paul, how dare you question anything I say FFS, you of all people should know better :bowrofl:

As for that useless post, it must have taken hours for that to be thought of

Figure it out - metal "traps" heat (err no, metal is a conductor) and plastic makes it run cooler because it doesn't trap the heat! So why not make radiators out of plastic, rather than aluminium?

Well why didn't you say that in the first post besides the crap you typed.
Thats all I needed for an explanation, not "lol lol"

Jesus you ask a question on here and get treated like you know nothing.

"As for that useless post, it must have taken hours for that to be thought of"


err no - was lost for words!

Clearly you have a wealth of experience on Magnas :nuts:

It is a common issue with the second gen. The relays run a lot hotter, the metal cap can get so hot sometimes you can actually burn yourself. These are very well known for failure. Also, metal will radiate heat but think of where the relays are, in a flaming box with no airflow!!!!!

Before you post your vastly informative posts mate, how about you actually contribute to the discussion or not bother?

The first gen relays are larger, do not generate as much heat, have better quality contacts within and also run a larger coil which takes less current to activate the blade.

But hey, dont listen to me, I have only replaced hundreds if not thousands of these in the last 20 or so years :nuts:

Also when you look at other cars, I can think of almost no cars that use the metal cap relay due to this exact problem

Mate, you know I was kidding. Was going to actually suggest he find all the good fuses in his car and replace them anyway
