V8 Overheating
Dr Strangeglove:
Cheers RRB,
I am pretty sure the fan is pulling through the rad but I will double check tonight. I will try the timing first as I do not want to take the water pump off and end up with broken studs etc. The plugs are also sooty so I think it’s worth trying the timing - just need to borrow a timing light.
I will also check with the fan speeding up (it is a viscous unit).
Thanks for all your help, it is greatly appreciated.
Regards
Mick

Just my tuppence worth, but if a rad is suspect (and not obviously damaged/clogged) replace it, i shant bore you with the story but we had a fleet of vans and tried flushing the rads out ect, all flowing through perfectly---- but still over heating, in the end we replaced the rads and hey presto ---- jobs a good un,
Range Rover Blues:
Yes I think the insides get a caot of limescale or some sort of cack that won't flush off and this is enough to reduce the efficiency of the rad.
BTW, I had a look at timing lights in Halfrauds and they have never been cheaper :wink:
bombx3:
get hold of a lazer thermomerter point it and it tell you the temp ie top of rad ,pipes cylinder ect aprox 86 deg all over at normal temps ,younwill find the problem in 2 mins,without touching a spanner
Dr Strangeglove:
Laser thermometer - what a good idea :idea: . I presume I need to check various pints on the rad and the suspect areas will have a lower temperature. :?
I presume also that if I check all the pipes, the ones leading from the engine should be slightly hotter than those returning. Any idea what the temperature should be (when stood and on tick over - or perhaps at a certain revs) as if the engine is running hot because the timings out then this would also be a good indicator for that!!
I will set myself a task of purchasing one and a timing light. I noticed a section on the RPi web site on setting the timing so I shall print it off and set to it.
Thanks for all the advice guy - it’s well appreciated.
