qim Posted December 23, 2016 Author Report Share Posted December 23, 2016 Hi having, hopefully sorted out my overhearting problems, I now have the opposite problem: the car is not reaching the correxct temperature in winter (12º to 17º C) What can I do to get it run warmer? Thanks camilo Quote Link to post Share on other sites
rhino_mac Posted December 23, 2016 Report Share Posted December 23, 2016 What temperature are you getting on your gauge? Mine sits at about 160 Deg F when driving normally in 18-20 Deg C weather now that it has been rebuilt with new radiator/water pump/hoses etc and the block was emptied of rust. When you're on the motorway in the cold it can drop to another 10 degrees F over time. I rarely get 185 Deg F unless I'm sitting in traffic. Quote Link to post Share on other sites
RogerH Posted December 23, 2016 Report Share Posted December 23, 2016 Hi Qim, you could place a simple cardboard sheet in front of the rad. Blank off the lower half or three quarters. Roger Quote Link to post Share on other sites
Don H. Posted December 23, 2016 Report Share Posted December 23, 2016 Perhaps try giving it a little more throttle. Quote Link to post Share on other sites
AndyR100 Posted December 23, 2016 Report Share Posted December 23, 2016 I have a suitably-sized piece of hardboard blocking half the radiator - does the job nicely ...... Andy Quote Link to post Share on other sites
Guest Posted December 23, 2016 Report Share Posted December 23, 2016 I have a suitably-sized piece of hardboard blocking half the radiator - does the job nicely ...... Andy the plastic bottom of a large shopping bag works great too. In wintery wet conditions a cardboard plate gets soaking wet. Perhaps not a problem in Portugal.

qim Posted December 23, 2016 Author Report Share Posted December 23, 2016 Perhaps not a problem in Portugal. Menno You're kidding! You've never seen rain before till you get here in some of the winter months! You mean, you block the radiator closing off the small area between the shroud? Quote Link to post Share on other sites
RogerH Posted December 23, 2016 Report Share Posted December 23, 2016 Yes. Roger Quote Link to post Share on other sites
Guest Posted December 23, 2016 Report Share Posted December 23, 2016 (edited) Ha! So it rains in Portugal? That's a good kept secret! We (Dutch) tend to fly down south this time of the year to get a glimpse of the sun in Portugal. btw, Portugal and especially the cities are getting more and more popular for weekend trips from Amsterdam. You can opt for a solution where you mount the plastic in front of the grill - that's easier installed and removed, but not so easy on the eye. You can also opt for a 'close to the rad' solution. It needs some careful trimming like rounding the corners to be sure you will to poke a corner through the core. Keeping it in place can be done by tie raps or tape. Off course you can't put a board between the radiator and the (aftermarket) fan... (My Saab came with a -roughly translated- 'cosy bra'. A padded, grill shaped plastic sheet that fits needly on the grill. You can mount it with a plastic like Dzus screws. But my Saab is a so called 'Arctic version' of the 1970 Saab 96: different interior heater thermostat (choose between 'hot' and 'this must hot as hell' - I can not remember that I've lifted the heater knob more than the first notch..., double door insulation: on the door and on the body, engine heater - heater element like you find on the bottom of a tea kettle and rear windows that cannot be opened. Preparing the Saab for the winter also needs an adjustment of the carb... little more fuel, less air for a little rich running. Starting is soon easy.) I remember owning a cosy bra for a TR4! i've sold it to a fellow member in Denmark. I can't find pics though. Perhaps there are North American solutions with a padded piece for the grill.

What would be the right name for those "cozy bras" so that I can google online? Did Triumph do something of the kind? Thanks PS- Yes, it's been very nice and sunny since Sunday. It poured for the previous couple of weeks. Good for the agriculture, or we would have to import tulips for our salads... Quote Link to post Share on other sites
Guest Posted December 23, 2016 Report Share Posted December 23, 2016 I think it was an after market item for Nordic countries. I vaguely remember that Alec knew this accessoire and the manufacturer's name. 'Winter blanket' perhaps? Quote Link to post Share on other sites
qim Posted December 23, 2016 Author Report Share Posted December 23, 2016 (edited) What's the name in Dutch/Danish? I will google them Edited December 23, 2016 by qim Quote Link to post Share on other sites
classic225 Posted December 23, 2016 Report Share Posted December 23, 2016 OMG Qim......, winter temps at + 12C................When I open up my shop door ,shut the heater off and push an old car outside to let it run for a bit...in - 33 C, it warms up perfectly...so if your car doesn't warm up at pos. temps there must be something wrong. And blocking a radiator with something doesn,t seem like a good idea. These cars were built to deal with....+12c without any form of blocking the radiator.

qim Posted December 23, 2016 Author Report Share Posted December 23, 2016 OK. So what could be wrong if driving at around 60 MPH and outside temp of 15ª The needle does not go to the centre of the dial? I had shrouds introduced in the summer to solve the opposite problem:overheating. Quote Link to post Share on other sites

classic225 Posted December 23, 2016 Report Share Posted December 23, 2016 Qim, Maybe you should check how accurate the temp gauge is. Use like a Fluke auto meter that can do temp readings and check how warm or cold that the car is really running. I had that problem with my old cooper s and discovered that the temp reading between C(old) and H(ot) was only 5 degrees. So maybe it is running at the right temp without showing it on the gauge.

Don H. Posted December 23, 2016 Report Share Posted December 23, 2016 Standard-Triumph had a solution for this problem in 1954... Quote Link to post Share on other sites
Motorsport Mickey Posted December 23, 2016 Report Share Posted December 23, 2016 (edited) Qim, When these cars were new and sold they were always serviced before winter and a different engine thermostat was fitted, quite common. The higher opening winter stat kept the water in the block for maybe 10 deg more and so of course the whole engine warmed up more and the operating temperature equalised around the centre of the gauge at about the summer running area. Also if you go on e bay you'll probably find a small roller blind within a cassette which screws to the front of the radiator (that's where I found mine). It was a period accessory and allowed the driver to pull the blind up from the drivers seat and block off more off the rad and reduce the airflow through the rad increasing the engine temp. Mick Richards OOoopp, see Don has just beaten me too the punch. Edited December 23, 2016 by Motorsport Mickey Quote Link to post Share on other sites
Lebro Posted December 23, 2016 Report Share Posted December 23, 2016 Is the thermostat working ? Bob. Quote Link to post Share on other sites
qim Posted December 23, 2016 Author Report Share Posted December 23, 2016 (edited) Is the thermostat working ? Bob. It's a new one. PS - Just read Bob's and Mick's posts. Thank you all. I start to get the idea of which way to go. OK. I'll order a winter thermostat. Edited December 23, 2016 by qim Quote Link to post Share on other sites
Lebro Posted December 24, 2016 Report Share Posted December 24, 2016 I use 88°C all year round. It's a bellows type with shield for the bypass. Bob. Quote Link to post Share on other sites
RogerH Posted December 24, 2016 Report Share Posted December 24, 2016 A rich mixture will also keep the temp down a small amount. Roger Quote Link to post Share on other sites
qim Posted December 24, 2016 Author Report Share Posted December 24, 2016 (edited) I will start by checking the gauge is correct. Can I do that at home, or do I need to send it to a specialist? Edited December 24, 2016 by qim Quote Link to post Share on other sites
