Overheating problems

[Jarediscool]

Hey all, I’ve recently been experiencing overheating issues when in stop start traffic, this wasn't a problem until about 2 weeks ago when i added an aftermarket exhaust. Just wanting to know what the process of elimination would be like for finding the problem. Cheers

Go through that. Clean the filler cap sealing surface. Get a new genuine cap on it.

In particular to the link is the air bleed procedure.
