The temp rises sharply when slowing down and the car blows out radiator water through the cap. It is fitted with an electric fan from Kenlowe (150 W motor) which is running ok. When traveling normal speed ( 40 plus km/h) there is no problem keeping the temperature normal. The thermostat is of correct type and opens around 78 deg C. The flow of water seems ok and I can´t detect any hotspots in the cylinder head. I measure temperatures between 105 and 110 deg C on the exhaust side of the head, the radiator cap is a 7 PSI cap. The carbs have been adjusted by an expert. The only part I have not mentioned is the radiator… it is the original and should have been rinsed at radiator company but … could the radiator be my problem?
I appreciates all ideas to solve the problem.
Is the fan pulling or pushing? There was recently a post in the e-type forum about someone receiving a new fan that was wired backwards.
The fan rotates correctly and pushing. I made the misstake to forget the fan when I went to negative earth! But the air flow seems weak for coming from a 150W fan.
Time to recore the radiator.
Modern cores are also cooling much better.
I recored the radiator’s of all my cars.
What is the typical cost of a recore?
Can we be sure what ‘pushing and pulling ‘ is being discussed/ agreed
A 150 rad cap should be 4 lbs.
If you have never had an engine overhaul the block will be full of rusty debris reducing movement of water.
