bignev Posted January 23, 2016 Report Share Posted January 23, 2016 Hi guys,Anyone else with a 3.3 V6 have their cooling fans come on before it's up to normal operating temperature?Just thought I'd ask, it's always done it.In fact all 3 of my GV's have.It's difficult to notice really, but a bugger on cold days when I notice it.It does it wether it's been driven, or idling on the drive say for oil changes, or just to run it if it's been stood.If I turn the engine off and start it up again they stay off.

0 Semmysonic Posted January 25, 2016 Report Share Posted January 25, 2016 Can't say I've noticed on mine. I will check and get back to you Quote Link to comment Share on other sites More sharing options...

0 Sheen1 Posted January 26, 2016 Report Share Posted January 26, 2016 Hi you have an electrical fault. One of the wires going into the ECU has severed. Cost me £70.00plus VAT at Jeep Chrysler Specialist in Enfield, north london. They have the full diagnostic kit for Chryslers. Quote Link to comment Share on other sites More sharing options...
0 bignev Posted January 26, 2016 Author Report Share Posted January 26, 2016 On all 3 cars?My code reader (that has read others on it) has never shown, any or pending, codes. Quote Link to comment Share on other sites More sharing options...
0 Sheen1 Posted January 29, 2016 Report Share Posted January 29, 2016 You have a break in the wires. I lived with it for years. The ecu sends a signal for the cooling fans. By all means check the relays. But the chrysler specialists in enfield fixed it within minutes of diagnosing it. They have the proper scanners. Others just cannot scan these vehicles. Check with ACD as well if you wish. Cheers. I have had so much work done on my chrysler, and come to the conclusion that only someone with the proper doagnostic machines for chrysler will be able to tell you exactly what is wrong with these cars. Something which waas backed up by the aa patrol. Quote Link to comment Share on other sites More sharing options...
0 bignev Posted January 29, 2016 Author Report Share Posted January 29, 2016 (edited) They aren't on all the time, work normally when hot, in traffic cutting in / out, same with AC when it's on, (mostly it's not).And it doesn't do it all the time.But definitely noticeable when not going anywhere on the drive as I said.

0 Semmysonic Posted February 2, 2016 Report Share Posted February 2, 2016 Sorry in the delay, checked mine the weekend while it was sitting on the drive and the fans don't come until a while after the engine has switched to lpg (which on mine means it's pretty much up to running temperature) Quote Link to comment Share on other sites More sharing options...
0 bignev Posted February 2, 2016 Author Report Share Posted February 2, 2016 Thanks for that, appreciate the effort.The fans come on when the gauge is on the mark below the halfway one, and full temp on mine is literally just under the halfway mark. Our first GV with LPG TECH used to not change over until it was a fair way up, but obviously in winter that could be a while, so my guys adjusted it so it swapped to gas at about the quarter line or just under - but hot enough so it heats the gas to work properly. Which is around where our "new" one with BRC does it. One or 2 very hot days in summer it started up and immediately went to gas, but wouldn't drive on it - just got a bit warm sat under the car port in the sun!!! Only 30 seconds of fast idle and it was away though. Quote Link to comment Share on other sites More sharing options...
0 Semmysonic Posted February 3, 2016 Report Share Posted February 3, 2016 That sound normal to me, mine never gets close to half way on the gauge. Quote Link to comment Share on other sites More sharing options...
0 bignev Posted February 3, 2016 Author Report Share Posted February 3, 2016 Cheers Semmysonic!All 3 did / do the same so probably some strange Chrysler wonderous thing. Quote Link to comment Share on other sites More sharing options...
Question
bignev
Hi guys,
Anyone else with a 3.3 V6 have their cooling fans come on before it's up to normal operating temperature?
Just thought I'd ask, it's always done it.
In fact all 3 of my GV's have.
It's difficult to notice really, but a bugger on cold days when I notice it.
It does it wether it's been driven, or idling on the drive say for oil changes, or just to run it if it's been stood.
If I turn the engine off and start it up again they stay off.
Cheers,
Nev
