Spence Posted February 5, 2012 Share Posted February 5, 2012 Apparently the matrix has been changed but noticed there is no valve under the bonnet at the back right near abs pump. Should there be one like the soarers? Appreciate any help??? Quote Link to comment Share on other sites More sharing options...
Dnk Posted February 5, 2012 Share Posted February 5, 2012 When its cold take the rad cap off and see how much coolant you can get in the rad. Is there any in the expansion tank ? Quote Link to comment Share on other sites More sharing options...

Will check tomorrow. cant get a decent pic on google and don't know another local owner to compare pipe work. Quote Link to comment Share on other sites More sharing options...
Spence Posted February 7, 2012 Author Share Posted February 7, 2012 Ok so there is no valve and levels look ok. Spoke to previous owner and could be something to do with the air box which I think is dash out time! Quote Link to comment Share on other sites More sharing options...
mwilkinson Posted February 7, 2012 Share Posted February 7, 2012 I think your referring to the heater matrix, although when this goes you usually get a wet passenger footwell. May well be blocked. If it is this you will need to remove the dash. Do a search for a thread by Jezz which details how to do this. Quote Link to comment Share on other sites More sharing options...
Spence Posted February 7, 2012 Author Share Posted February 7, 2012 The matrix had been replaced. I checked with him that the pipes were correct. If this was a skyline I could have done all the bits blindfolded lol. Quote Link to comment Share on other sites More sharing options...
mwilkinson Posted February 7, 2012 Share Posted February 7, 2012 Sorry Spence, that was clearly a comment made without reading the bloody thread. So to get this right, it's not the fact you get warm air from the aircon, but instead that regardless of how hot you set the heating it only comes out warm? If the latter, it could be an air lock? Get the car up to temp and turn the heating on full. Check the two hoses that go into the bulkhead to the heater matrix and see if they are getting hot.

Spence Posted February 7, 2012 Author Share Posted February 7, 2012 Yeah. I matter How hot the engine temp is, of you put the hot air on full it still won't put out hot air. Quote Link to comment Share on other sites More sharing options...

Spence Posted February 9, 2012 Author Share Posted February 9, 2012 Pipes are hot. Quote Link to comment Share on other sites More sharing options...
mwilkinson Posted February 9, 2012 Share Posted February 9, 2012 Hmmm. So you have hot water going in and out. Were they both of a similar temp. When you say hot were they "I can't grab them for too long" hot? My next thought would be a possible motor failure of air con contol ecu or control unit issue. You can do a diagnostic on the air con system which might give us a clue. Let me have a look and get back to you. I'm just getting on a train from Waterloo and will have a look once I'm on the move.

Spence Posted February 9, 2012 Author Share Posted February 9, 2012 I have a diagnostic machine so will plug it in in the morning. Pipes were warm but car wasn't up to temp. To be honest I really don't have time to look at it. I own a garage and a hand car wash and we are flat out busy so just after some really quick fixes. I'm bloody freezing lol. I read through a thread about the flaps so that might be an option. Got a load of other stuff gone wrong now as well. O/d and tc lights flashing, belt or pulley making a right racket, alarm going off for no reason, boot struts not holding open boot, dimmer switch doesn't work etc....

There are no quick fixes for that LOL. Will PM you with the diagnostic procedure which can be done from the control unit in the car, no need for any additional machines.

Spence Posted February 9, 2012 Author Share Posted February 9, 2012 Thanks mate. If we weren't busy I would investigate it but my tech can't even finish work he has booked lol. Quote Link to comment Share on other sites More sharing options...
Scooter Posted February 9, 2012 Share Posted February 9, 2012 belt or pulley making a right racket.... check the crank pulley, these can delaminate......it's a common thing......it also drives the water pump and so perhaps if the pulley is really bad and only half turning the ancillaries half spinning on itself it's not providing the water pump with enough 'go' to circulate the coolant as it should?

Guest kinkydeviltom Posted February 18, 2012 Share Posted February 18, 2012 Have a look under the passenger side footwell closest to the centre and look up, find the silver rod and see if it moves wen u turn the temp control Quote Link to comment Share on other sites More sharing options...

Is that what was wrong with yours? Quote Link to comment Share on other sites More sharing options...
Dave Posted February 18, 2012 Share Posted February 18, 2012 is the flap working behind the top glove box maybe its not shutting .if you remove the box you will be able to see it move when you move the heat control bar. Quote Link to comment Share on other sites More sharing options...
Guest kinkydeviltom Posted February 19, 2012 Share Posted February 19, 2012 Same here, nah my rod doesnt move which im thinking its the heater controls but as you know its having the time Quote Link to comment Share on other sites More sharing options...
