SilverEsprit Posted April 22 Report Share Posted April 22 (edited) Pretty sure it's this container at the rear right engine compartment whose cap reads, "TURN DOWN TIGHT - AC - REMOVE SLOWLY," but I want to double check since the seller who owned this for 20 years told me this was an AC system freon tank. This is my first time looking into it and want to be sure. Edited April 22 by SilverEsprit Quote Link to comment Share on other sites More sharing options...

CarBuff Posted April 22 Report Share Posted April 22 🤪 'AC' is the brand of the cap! The coolant header is at the RH lower corner of this picture from the 'net.

SilverEsprit Posted April 22 Author Report Share Posted April 22 Yep, that's the one! Giniw, here's a pic...always a good idea and I'll keep this in mind for future questions--thanks! 1 Quote Link to comment Share on other sites More sharing options...
SilverEsprit Posted April 22 Author Report Share Posted April 22 (edited) Speaking of checking coolant, I've opened the container and see a bunch of corrosion inside. I think it's time for a new one! PO was having an overheating issue and thought it was the radiator fans. I decided to check coolant level first and it's pretty low, near the bottom of the container. Should it normally be full / topped off? Corroded container could also leak in theory. I'm thinking I'll get a new container and flush/replace the coolant, then monitor it for other issues.

CarBuff Posted April 22 Report Share Posted April 22 (edited) Yuk. I think a coolant flush is warranted. You MAY need to drop the radiator and re-core. Don't forget to check flow through the heater matrix, either. The normal header tank fill level on G-Esprits (that do not have a reservoir in the LR trunk) is about 3/4" lower than the bottom of the filler neck (cold).

Giniw Posted April 23 Report Share Posted April 23 I am a bit late to the party but indeed it was the coolant tank indeed. I hope the previous owner did not maintain the car himself! (To me such a thing as an A/C freon tank doesn't exist anyway, so ... ) Quote Link to comment Share on other sites More sharing options...

If the PO had no idea how to check the coolant level, I wouldn't put much value in his thought on overheating... Start by flushing and properly filling/bleeding the system, than use the car keeping a close eye on the temperature gauge. Chances are everything will be fine with the coolant level as it should be. As long as the tank isn't leaking, no real need to replace it. A good clean is probably all that's needed. 😉 1 Quote I have made many mistakes in my life. Buying a multiple Lotus is not one of them.

snowrx Posted April 23 Report Share Posted April 23 If it's been rumored to have over heated and is low on coolant, you may want to do a coolant combustion gas check to see if the head gasket is OK. Especially if it loses coolant after topping off. Custom alloy header tanks are available to replace the crusty rusty, I just adapted a generic ebay item with larger capacity.
