junglesponge Posted June 3, 2018 Share Posted June 3, 2018 Hi everyone, I’m trying to troubleshoot a problem and I need some help. I have a 1968 mk2 cortina with a 1300 Crossflow motor. The other day was running it at idle as I hadn’t started it for a few months and went inside for a few moments. Come out and it was warming up nicely and a few minutes after that I noticed water expelling from under the car. I checked temp which was getting very high and when I opened the bonnet water was streaming out the little overflow pipe under the radiator cap. When it had cooled a little I opened the cap and put water in but it filled quickly. I have replaced all parts on engine with New including water pump, radiator pipes and thermostat. I was also wondering if my fan is facing the right way? Anyway if you could give me any advice it would be much appreciated. Quote Link to comment Share on other sites More sharing options...

66gt Posted June 3, 2018 Share Posted June 3, 2018 Check the radiator. Core could be all blocked up if it’s old and not been used for a while. Going by you saying that it took bugger all water to top it up, I’d say the radiator is fucked. Quote Link to comment Share on other sites More sharing options...
Nominal Posted June 3, 2018 Share Posted June 3, 2018 Ignition timing correct? Fan looks right BTW. Quote Link to comment Share on other sites More sharing options...
junglesponge Posted June 4, 2018 Author Share Posted June 4, 2018 I sent it away to get reconditioned but it could be a issue. The water did look a little rusty to be honest. Where could I get a new radiator from? If it’s a air lock how to I bleed that out? Quote Link to comment Share on other sites More sharing options...
66gt Posted June 4, 2018 Share Posted June 4, 2018 Just take it to any radiator shop and they will tell you if it’s fucked or not. About 4-500 for a new core Quote Link to comment Share on other sites More sharing options...
peteretep Posted June 4, 2018 Share Posted June 4, 2018 check thermostat is working too, I had one fail and car started getting real hot, didn't get to the point over water overflowing though Quote Link to comment Share on other sites More sharing options...
