    I have a mg Td deluxe built in 1986. I have gone through 2 Chevy engines and have now tried a Toyota 22r. I can’t seem to stop the engine from over heating. I have installed an electric fan but still she gets hot.i have also had the radiator increased to 4 cores. Anyone ever cut the vents in the sides?? Any thoughts?

    Hey Elmo,

    My mid 80’s British Coach Works has the vents routed out on the sides. ¬†With the exception of one time (hot Summer Day and a slow radiator leak I forgot to check) where I ran hot until I topped things off, my engine seems to cool just fine.

    My gut says venting (where the vents are supposed to be) may take care of your problem.

    May sound silly, but I’ve seen the electric fan installed incorrectly and instead of sucking air through the radiator it is trying to push the air forward, completely defeating its purpose. With the 4 core and a working thermostat, venting should be unnecessary.

    Like Bill said. Check all the things. Make sure there is no air in the system (a problem in my car with the engine so far away from the grill). Make sure you have a good fan shroud, good thermostat, good water pump, fan belt, fan (turned the right way), all that good stuff.

    If all that checks out, and she still overheats, then think about cutting the louvres.

    The replicas had fake louvres and did not usually overheat; missing them is not your primary issue.
