printedflunky 9 Posted January 30, 2011 Report Share Posted January 30, 2011 My 98 vr6 used to run oil temps of 95+*c all the time which I've been told is as its supposed to but now it won't get above 82*c without kicking the arse off of it and even then it only goes to 90*c, also my water temp will not go above 1/4 (75*c) .What could be the cause for this as its also affecting the heating in the cabin.One quick note she's regularly serviced and doesn't lose coolant, any help would be greatly appreciated.

printedflunky 9 Posted February 2, 2011 Author Report Share Posted February 2, 2011 thanks for the advice guys, it turned out to be a blockage in the heater matrix. Found it by looking under the bonnet with the engine running and noticed one of the rubber pipes from the heater was sucked flat. I took the pipes off and put my garden hose up the end of one of them, put a kitchen sieve under the other and turned on the hose. you should have seen the sh*te that came out! I also did a complete system flush using the same method and now i have hot air in the cabin and lovely fresh anti freeze on the driveway. Link to post Share on other sites
